"black hole" Discussed on NASACast Audio

"As of detecting black holes require that some other object be present but if the black hole is flying solo with nothing nearby orbiting it and nothing nearby. There's little chance that we will ever notice it. We will likely only get to know a fraction of the millions if not billions stellar mass black holes that are estimated to live in the milky way alone stellar mass and supermassive black holes are vastly different in mass and for a while scientists thought there might be no black holes with masses in between these two extremes but recently with the help of the hubble space telescope astrophysicists found the best evidence yet of intermediate mass black holes nez chandra and new star. Telescopes have also been exploring these newly discovered middleweights. Now it's time for us to explore a black hole up close and personal. Let's take a journey into one. Say you were floating towards the black hole now. Let's suppose that you are approaching a stellar mass black hole and that isn't actively consuming star stuff because if it were even being near the black hole could be deadly. I certainly would not want to be in the past of a black hole. that's active. Lean eating up these stars date things and then they kind of like particles at the speed of light. Lots of high energy particles do not mix well with life. So let's just assume you approach a lonely black hole by chance because you wouldn't see it now as you get closer all of a sudden you start feeling this tugging on one side of your body but not on the other basically the first part of you that was starting to get closer and closer to the black hole would start to experience the really extreme gravity that was near the black hole. Save you were going feet. I you know your feet would start to be stretched apart. Your body would basically start to stretch like kill liquids yet. East does even a technical term for it. it's called spaghetti affiliation basically just rip you to pieces. You probably wouldn't survive but just for fun. Let's say you did survive. Part of you would crossover into the event horizon and the rest of you would probably be following pretty soon after this only happens with stellar mass black holes where you can feel that change in gravity but if you've found yourself entering a supermassive black hole you wouldn't feel a thing all of a sudden you just be inside the black hole never to be seen again well kind of. Here's the crazy part. If your friend were watching this happen to you they might see you get stretched but what happened really slowly until at some point. It might look like you were frozen time like you never pass through the event horizon. That's because get stretched out by the immense gravity that a black hole produces really benz the reality of our universe and the reverse happens from your vantage point. So if you were looking out at your friend it would seem like they were moving through life at warp speed. If somehow you weren't ripped apart by the gravity or manage to survive the radiation near the black holes of that horizon will then you would get to enter the black hole once you're in you're stuck and that becomes your universe what would you see and feel we don't really know we can only theorize but at some point you would become one with the singularity essentially you'd be compressed into a tiny speck so i would not recommend traveling to black holes at least not that close and luckily it shouldn't be too tricky to avoid them the nearest black holes we know of our thousands of light years away from us meaning it would take thousands of years to get to them if we could travel at the speed of light which we can't not only will they not be eating earth there too far away for a visit from earthlings by now the universe is peppered with black holes with new ones forming all the time and some black holes keep expanding as they consume more gas but how and when does a black hole die even the ones that are creating hot gas in her very bright. They only do that for a very short part of their lifetime but eventually they'll all just run out of fuel even if they have a star orbiting around them. That won't last forever they really. There's nothing left for them to do just going to. They're just going to sit there. And for the most part all of the matter inside the black hole. We'll stay there as well. What happens in a black hole stays in a black hole. There's only one theorized way that anything can escape a black hole gravitational grip. There's an interesting results. From stephen hawking famous theoretical physicist. Who showed because of these quantum mechanical effects. A tiny bit of radiation can actually leak out of a black hole called hawking radiation but in practice such a tiny tiny tiny. The fact i we will never be able to observe it and second. If you have a star ten or fifteen times the size of the sun it would take trillions and trillions of years before it even changed a little bit. Because of the hawking radiation once.

UK to bolster defense spending by 'most since Cold War'

"Today. The prime minister announced a once in a generation modernization of the armed forces as part of the integrated defence review which will give around sixteen billion pounds. The army of the next four years. James has quite a bowl claim from the prime minister. Dad do you think that's sort of once. In a generation modernization of stacks up or with covert we what so used to big numbers being thrown around twelve billion pounds testing trace but it is worth noting that this is significantly more money for defense van the government had promised dettori party app promised in its manifesto and it's very unusual that governments and not on popular things like defense spending spending more than they told the voters they would at the election. I think it reflects an attempt to fix this thing that has been around in politics. I already covering westminster six. The mo d black hole. Basically sucks money into the budget. Always attempt to fix that sent to modernize reporters weren't very different world. You have frequent different frets to the uk but exist in quite different spheres so in china. You'll have something that we haven't had since the end of the cold war which is a classic great power rival tweak. The uk's role in that is as supportive powers. Paul we're kind of american led coalition but by obviously he's going to cost money to deal with that then you have russia which is primarily exists in cyberspace. Disinformation all those kinds of issues. And then you have the continuing terrorist threat. And because you're having to deal with three different for us at take place in three different theaters. That is on busy. Going to require more money. And i think that if you look at what is saying today about restoring the uk former his naval power. I mean there are some of other political messages hair. I think as a message to the incoming administration that the uk is still serious about defense is going to be the second biggest military spender in nato. So let's have a good relationship. I think it's a subtle but implicit message to european. You have an interest in the success of economic as the uk is going to be spend serious money on the defense of the european concerned the wider western world. And then if you look at ambush was talking about shipbuilding where ships can lots are going to be built in scotland. He has long been in the decide this answer. Uk during the election campaign that one of the ways he was going to boast of a union wars to build more ships in scotland. He fought but that kind of industrial street would have a good effect. I think there is an interesting question. Which is the cost. here is obviously the question. I do think there has been some interesting. I haven't research in the. Us defense spending is particularly effective form fiscal stimulus which is going to be needed post. Covid but i think the longer term issue is can you so his constant procurement problems in the energy that created the black hole in the first place. Because if you call do at even this really significant amount of money isn't going to be enough to turn things around for good

New York - New Jersey poised to legalize marijuana

"The Frog said. It's not easy being green. We're about to find out if Kermit the Frog was right, New Jersey's become a green state the 11th in America to say it's okay if an adult wants to light up or vapor eat a plant that has been villainized by the alcohol lobby ever since Prohibition, with great success, but at the expense of social justice, the legalization Recreational cannabis raises many questions about when how, where, and what happens to the records of all those who've been convicted of what is now okay. Sean Adams is here this morning on this story. Sean. Good morning. How overwhelming is this green wave in the garden state? You are not all the votes are counted, but it looks like about 67% of New Jersey voters said Yes, the legalizing recreational pot for adults. 21 polls have been pointing in that direction for some time. As New Jersey grapples with a covert inflicted budget black hole. There's a tremendous monetary incentive here. But for Governor Murphy, the motivation he claims is different. I get there because of social justice I inherited A state that had the widest white non white gap. The person's incarcerated in America, and the biggest reason was low and drug crimes. So this will go a long way toward a better a better reality. In that respect. Now lawmakers still have to make this legal They have to consider a decriminalization bill. Then lawmakers in the commission they have to. They have to get to work on a lot of the nitty gritty the rules and regulations for Cultivation, testing, distribution taxation. We should also note that there might be a domino affect you in the Northeast. This could put a lot of pressure on a couple of other states, Pennsylvania and New York. Especially in New York because there's there's a lot of tax money at stake here, and there could be a massive loss for New York tax dollars going right across the bridge and tunnels

How the COVID-19 Pandemic Shed Light on the Digital Divide

"Today I'm happy to have with me two excellent guests to address I. Think a very significant issue that we've known about for a long time, but has become especially poignant during the pandemic, not as the digital divide. A lot of us have you know with some bumps along the way made a fairly smooth transition to living life onscreen. But there's a lot of folks out there who have not, and that is because they continue to be and before the pandemic, there were very large disparities between who had access to the types of tools necessary to live in this new virtual world and who had the. Skills and the background necessary to thrive world that looks like it will be more virtual in the future than in the past even when pandemic has passed the to talk about these trends, I've two terrific guests. Kimberly Bryant is the founder of Black Girls Code Jessica Rosenthal. Soul is a commissioner for the Federal Communications Commission and were I hope we will have a great robust discussion about these issues. Just, let me start with you the digital divide. It's very old term. It's been around a long time. What did we learn? That's knew about it from this pandemic. Well, thank you for having me ads on what's important now is that the digital divide has been exposed s pandemic. Because now, we see conclusively the hard truth that our nation's gapped in digital skills. Digital access is very real and very big. And if in Washington, we used to think about broadband Internet literacy as Nice to have this pandemic has proven that it is neat to have as a nation were online for school for education or work for health care for entertainment and so much more. We've got a recognize is that we are not going to live up to our civic and commercial potential. If we don't find a way to connect everyone in this country, you've talked about the homework gap as sort of like the analog to digital divide tell us about that and what we've learned about it and why it matters. Yes said being the before times before we are all in home there was this thing that was happening that I noticed, which was that teachers were increasingly assigning homework that require Internet access. But what I know from the FCC is that one in three households do not have broadband? and. So the kids who lived in those households in just fall into a digital divide they fell into a homework they could do their nightly schoolwork I mean when all of us were growing up, you know we need to paper and Pencil and a clean. Spot on the kitchen table around a desk, but you need Internet access now to successfully participate. In school and that digital divide on Homework Gab has just become clearer in this crisis we said millions of kids home and told them to go to virtual classrooms. But if you don't have Internet access, you're out of that virtual classroom and we know it because we've seen chilling pictures on social media of hid sitting outside of fast food restaurants with laptops just try to access free Wifi signal so. They can go to online school and I just think in the United States. Of America we should be able to come up with policies that closed at hallmark gap. So no child is offline. Thanks can let me turn to you for a moment obviously One of the things we know about the digital divide is that it's more pronounced among certain historically disadvantaged groups, including people of Color and women. Black Girls Code I believe was founded to address both those saints tell us a little bit about your organization if you could just to start out absolutely on. Thank you again for having me on black holes was down right here in the bay area where I am today in our goal is said, is to address this issue around diversity inclusion, any equity in the technology landscape our focus is really to target girls Monday represented communities so African American. Students Hispanic Students, American. Students who are traditionally disenfranchised from Tech rears which actually pay their are look at content can change the trajectory of families in. It's not communities. We do that by really interesting girls as. Young as seven all the way through eighteen plus the skills and technology and teaching them about coding robotics game development. CETERA. So really try to introduce them all the different assets of the technology industry and also get them skills that allows them to either be creators, innovators, or the leaders of many of its expertise may see in the future

Change, Loss and Timeless Love

"Nama stay and welcomed my friends. Really glad to have you with us. I was recently perusing two different articles. The first title was aging the secret to happiness and the second was WANNA be happier. All you have to do is get older. So same theme and they both draw on research that teams to confirm this correlation that the older we get the happier we are. Now I know that seems counter intuitive given the challenges we face that we. Lose, people we love and we lose our youth and our health and our memory. I saw cartoon this very old couple and they were both on rockers on the porch and he's responding to her. He says, now you want an open relationship. Of Billy Crystal, but it this way he said by the time, a man is a wise enough to watch his step. He's too old to go anywhere. Okay so there's this evidence that Carlos aging with happiness and the understanding that resonates for me is that through our our lifetime, we have the capacity to learn and adapt and spiritually evolve and. With the passing of time. There can be a growing acceptance of the inevitability. Of Change and loss. A growing acceptance. Of Change and loss. and. Walk. Clearly, this doesn't happen to everyone for those that do deepen in that acceptance. Nabil's living and appreciating the moments. And loving were fully. So the title of this talk, and the one that follows is change loss and timeless. Love. And the theme arises from a central teaching on the spiritual path and. That is that our capacity to live and love fully is totally intertwined with how we relate to change and loss. So. This'll be AH invitation for you to look in your own life at how you're relating to change and loss. It feels really relevant right now to explore this given, how many people around the globe are experiencing such rapid change and real loss due to global pandemic and Deepening social divides and climate change the devastation to this earth. And while it may feel like change a speeding up. impermanent. So what really makes us clutch? Is really the nature of all takes form. And we know it on the on the largest sweeps. If you think of the history of the Universe Big Bang and stardust forming and planet earth elements combining to create this amazing variety of life forms and then Homo sapiens evolving tools and art and science and war and slavery in plagues and collaboration innovation. The whole thing you know empires coming and going Greeks the Romans, the Ottoman. Empire Portuguese the British the American. You know rising to dominance and then passing we always think things are for good but it all passes and here we are. On the brink of destroying. Earth our home. Seeing species common species become extinct. galaxies. Of Stars collapsing into black holes, it's all in permanent. And then. We can sense it on the most minute level you know if right this moment. You take the time to perhaps closure is and bring your attention inward and hold still really still. You can sense that. The body everything inside a moving if you feel your hands is anything holding stelle. It might seem that way if you're very very tense but if you even begin to relax a little, you can sense the hands feet. In the face. The Heart Everything's moving. Nothing hold still there's this. Ever changing flow of sensations feelings. Sounds come and go. Your body's replacing sells millions per second. Within those cells nonstop motion.

From instagram or kickstarter be are the creator of baby, Lenormand deck and I won't explain anymore I want them to introduce themselves. So High Tea can you? Like number one. In. So glad to have you here. Can you tell us a little bit about who you are your identities pronouns and what it is that you do? Sure I am t I am the founder and Co owner of grandma baby apothecary. I. Actually The grandbaby Public Kerry recently became co owned by my brother to whose name is Ian He won't be honest interview. But Yeah. recently to the kickstarter for the Black Goal Lenormand deck my pronouns farm going out of order are. She her hers And I'm really excited to be here. Thank you for having me. Thank you for welcoming now and. Thank you for joining me here I really appreciate you taking the time to do this. I know that they see her twenty twenty has been a really a wild year and you also have a lot of really cool stuff going on like you mentioned with the Black Hole Lenormand deck I know that we have been following. Your update from kickstarter. Folks at home like. Kickstarter, is amazing place to find these really cool index. And was one of them that I found I. Actually I think I found you via Instagram, and now we're at the point in your like kickstarter process where it looks like have you started to receive the decks They should be I. should be getting the which McCall it mood tracking number. For, my decks and the next couple of days and they should be on the way to me, which is kind of freaking me out but. But also, like I'm so ready, I'm so ready for them to be here. I'm ready to send them out ready to be able to hold them. This is like I don't WanNa say it's surreal, but it's very feels very good to have brought this from like a little idea to like a full. Full thing. Like I just like I wanna like mentioned in general like what monumental feat by is number one, and then like number two to have like gone through that like during the duration of this year, which has been very challenging the stabile least and Can you say like a little bit about like was that like easy? Was it? Did it make it more challenging? Experience running like whole campaign Emma through it's kind of a turbulent time so to speak. Will I mean I think I struggled since I was a kid with wanting to Have other people look at my art and like look at my things read little pawns and stories that I wrote So when I came up with this idea You know I kept seeing messages of like okay. Now you have to share it. Okay. Now you need to move forward with it and I was like y'all don't understand if Mike. my spirits like in an Miam- ancestral veneration. I just they. They were like, okay like you gotTa do this right in unlike. Like I don't know. Like 'cause you know I'd also like I'd really tried my hand at also like Having the regular office job or doing like you know different like graphic design jobs for people and an Anna working for other people I guess and their disliked. That's not gonNa work for you like you know that we know that so then. When Cobra hit I was like, well, I waited too long like this isn't GonNa work like obviously like this is not the best time to be asking people for money they like. Nate you should do it. I was just like, okay. You don't understand how these things. But. but then I did I launched it and It was terrifying by I'm really glad that they did I'm really mostly glad because it's put me and direct. In community with so many amazing people. That's I think the best part of what's come out of this that So many people have supported this not just financially on which is sort of what kick starters for but people have. Messaged me, they've sent me. like a kiss this week people were sending me like music at It feels really nice to have. To have this, I guess this opportunity to. mean during a pandemic have so many people who support an appreciate what I'm doing.

Event Horizon - Horror Movie

"We thought we'd take a horror movie and look at the Science and technology in that movie as well. Just kind of discuss what that horror movie is all about sort of the same way we did Independence Day back for the fourth of July. Now. There aren't that many horror movies that we could think of that have a heavy tech angle. There are some and there are plenty and we also we wanted to do something that isn't. As completely offensive as it could be it it's the movie that we is rated R. and I think both of us enjoy. For from kind of tongue in cheek way sometimes. Yeah. I. Genuinely Enjoy this film, but it is not what I would call a good movie is event horizon yes. It is a space movie. It's movie set and space. It's all about space Let's go ahead and give you an overview of what the basic plot is keys. You haven't seen it right? Although I will say that the this this discussion is going to involve lots of spoilers and We do enjoy this movie I want you to see it and to not be spoiled when you go into it. So if you have not ever seen the film and you were of an appropriate agent constitution to watch the thing with with kind of gory violent and mild nudity. Occasional cursing then maybe maybe just turn this podcast off and wait until you can watch the movie right now I will say since the film came out in one thousand, nine, hundred, seven, all bets are off so he ran go basic plot. All right. You've got to ship it's called the event horizon and it's supposedly a research ship that's meant to explore the further reaches of our solar system and on its maiden voyage. said. Just beyond Neptune. Now that happens in the year twenty, forty, seven years later a research. Rescue ship rather is sent out with a particular engineer scientist who had worked on the event horizons. Propulsion system actually designed to the entire ship Yup. So he's he's going along with them. They don't know what their mission is when they first leave, but they are to go out to Neptune and try and find the origin of a mysterious transmission that apparently came from. And rescue the ship and the crew if at all possible right. So they go out there and bad stuff happens the all. First of all, it turns out that the event horizons secret propulsion system is something that is called a gravity drive in the movie and the ideas that it kind of A. With space right? It creates black hole. Essentially, we'll get into that a little bit more later on. Yeah. Well, that's. We'll we'll discuss the entire black hole thing at link because it's interesting. It's what's really interesting is how much of the science the movie at least attempted to get, right? Yeah. Yeah. I I want to give it a lot of Kudos I do think that it really tried Goldstar you try. It didn't just use black hole as some sort of magic magic place home it. Right they tried to find a way of explaining this and there is some scientific basis for some of the stuff they talk about anyway because it's a horror movie when it tried to create this whole in space time to travel through instead it acted only ended up in a hell dimension. The identity bunch of hell back with it, and so there's is haunted. Trip is haunted by Hill and or is hell itself could actually clear possess town. It's a little weird. Yeah. So the idea being that that when the gravity drive is is Activated, the ship travels through a dimension in this case, a hellish dimension of pure chaos and evil as what intersect quote. Yeah, and and that yeah, it brings something back and the crew is deader than dead Super Dad. Yeah they are so dead. You see lots of really really dead people and and then the rest mission comes aboard and tries to do what? They're supposed to do and then hilarity ensues we won't Spoil Everything But essentially obviously, you have to dismantle the rescue ship or else they just leave. So that gets of then you have to separate out the crew members for various reasons have terrible things happen to them, and all this happens at great Gore and and detail, and it's entertaining. It's not. About Shakespeare but it's fun.

"Next came the physics. It's winners can boast they share an honor with Albert Einstein and Marine Pierre Curie Alex, tell us about this year's winners. So there are three winners this year for the Physics Prize. Goes to Suraj, penrose, who's a physicist and mathematician? He's one of the most prominent scientists in the UK. He's almost ninety years old. He's a permanent and everything from very mathematics to cosmology to material science. He writes puzzles. He's he's a real polymath genius and it's about time he wanted to Nobel prize. The other half of the Nobel prize goes to you Andrea Gez who is a professor of Astro Physics at the University of California Los Angeles and Heart Kansal he's an astrophysicist at. The University of California Berkeley and together the three of them win full increasing understanding of black holes. So Roger Penrose created some mathematical tools in the sixties that built on Albert. Einstein's general relativity the theory of gravity in the universe and several Japan rose created a way of using general relativity to predict black holes in the universe. So how they might actually form and then Andrea gas and reinhard denzil independently lead teams starting in the nineteen ninety s to track the orbits of Stars. Around. Sort of an object that sits in the middle of the Milky Way, our home galaxy, and there they were attempting to show that the object at the middle of Galaxy was indeed a black hole and they proved that with over twenty years of measurements

"Have won the Nobel Prize in physics for their work on black holes. CBS News correspondent Elaine Cub has a story. This year's physics prize celebrates what the Nobel Committee called one of the most exotic objects in the universe. Black holes have long fascinated humans. Britain's Roger Penrose received half of the prize for proving in 1965 that black hole formation is possible, largely using Einstein's theory of relativity. The second half was shared by German Reinhardt, Denzel and American Andrea Gaze for the discovery of a supermassive compact object at the center of our Galaxy. Elaine Cobb,

"Exactly as expected. Doctor who sound over her dr who than doctor who so there's video that explains the way better than I did with cool sound and it shows like the whole thing working. Yeah. As it gets lower, that's a speed, this the disc spinning up and lowering the sound as it matches the sound, and then like pushing the sound waves I guess as it comes out the other side making them faster if we can use black holes to create energy. Well I guess we can't use the sound was to create energy because we have to make the sound waves and that took energy I think the key is something big huge in space that we didn't have that. We don't have the power. Yeah. It's not creating energy, right? It's like stealing energy. Yes and it would slow down the black hole a little bit every time he did it too. But like oil like a little bit. Yeah. But if you were an infant race of space allowing super beings, then eventually that would be a problem. I suppose you just go from Galaxy to galaxy sucking up. Depleting entering black holes. Yeah. Yeah. That's what that's what the people who live on the planet are doing, and they're slowly going to stop their black hole. That's what the science fiction stories about Yeah. Instead of like having a fossil fuel shortage or something in hand, it's black hole. We're running out of coal guys. Yeah. The scientists are like I think that we're running out of black hole and the before that sound Johnson we're fine. Okay. So now you. Stuff and you have to decide which fact you like the most do you like a colliding galaxies with mismatch central supermassive black holes can propel their new combined black hole away and have wander around the galaxy furrowed while or Sam was scientists modeling matter escaping a black hole using sound waves and spinning foam as evidence in favor of an old theory proposing that we could use black holes to generate energy three to one. Oh. You. I'm surprised I got one. Sam. That was so cool I have. Had I've read it for so so long? China. Talking about. And if I'm wrong, tell me on twitter please and now it's time to ask the science couch where we've got listener question for our virtual couch. Finally hone scientific minds. It's from at Jake e Kennedy who says could there be some sort of opposite to a black hole like if it was an Audi instead of an inning. So what we like I, mean there's two ways. I can imagine this either you have like a bunch of anti particles that have collected. So you actually have like an antimatter black hole. Oh, or I guess that's it. 'cause like like zero density is like all over the place we have lots of areas of zero density and it's not particularly interesting. We'd need negative density. So I don't understand antimatter at all. No not meal. But I can tell me if it fits into the. I did look up a HAL general relativity. So the thing that is done is like general relativity these laws help govern our universe says that anything that happens forwards can be radically happen in reverse and this is true for both space and time even though we've mostly observed time just going forward rather than happening in verse but according to the math, it can happen backwards and may yet who knows we could start rewinding someday. Yeah physics as weird I don't understand it but based on that principle that anything that happens forwards can theoretically happen in reverse lack holes. Sucking stuff into their singularity can theoretically have an opposite called a white hole that are expelling matter out of the singularity passed the event horizon it and it would be a white hole instead of a black hole. Me because instead of like sucking in all the lights so just looks black it's it's so bright because it's just vomiting rainbows or like. What does the white hole also have infinite density? Yes. Sue the so it's like infinite density but in reverse no with a last long time or just be like instantaneous infinitely bright blasts of light. There are many reasons why this is so hypothetical that many scientists don't think it even can happen. So the second law of thermodynamics is that entropy across the universe must increase, and so that's like the idea that like if. I have a bookshelf and I have a bunch of books on it, and they're all ordered. There is one state in which they are ordered. But if I had knocked them on the ground and a pile than their disordered, and there are Watson different ways that they can be disordered and that's increasing entropy I think the concept of a white hole is that and this is where I don't get it exactly because. My visual of this is a vacuum cleaner spewing in reverse but like inserting things in to the universe would be decreasing entropy and so like a white hole with theoretically rake that second law and it could be possible if like net entropy across the universe was still increasing then decreasing in one little burst into Whitehall. So basically, I used all those words to say that if this hypothetical thing happened scientists think it would. Be Very short like short bursts of things coming out and then collapsing back in on itself to form a black hole, which is entrapping favorable there. There's a group of scientists that think that the big bang could have approximated a white hole because it was just like a bunch of stuff all at once. So so sorry is every just like let me know if every black hole creates a universe just let me know. Right, just like send me an email when you work that one out are just a text that be crate is every black hole poking through and making a an entire universe of its own somewhere else where just because I like you know ultimately they say this universe is infinite but I want this to be a an infinite universe of. That's what I want. Is that too much to ask and I want to orbit one I wanNA orbit a universe on a planet I want my own private. Thank you jake for your question. If you want to ask the science, catch your questions, you can follow us on twitter at sideshow tangents rule tweet how topics for upcoming episodes week. Thank you to at Acer gray at NJ Jenkins and everybody else who tweeted as your questions this episode I like how he put N. G. Jenkins like he is not nick our CO worker.

"black hole" Discussed on Daniel and Jorge Explain the Universe

"Right. Like if you want. If you're pushing someone on the mirror go rhino and make them go faster. You can push on the edge you could you could over spin it. Maybe so if we take all those spinning toys that kids were playing with is a couple of years ago you know the ones that would into ball. Bearings fidget spinner saved spinners. That were huge fad. And you tossing. Villa listen to Bruce Willis to deliver. Let's get back on the ship. We have a new idea that we're you'd be easing but that's basically yes I mean you saying if you give the throw a bunch of stuff that has a lot of spin and in my shrink the the black hole yeah and this crazy is theoretical idea. Nobody knows what it would actually work. But if you did that you might be thinking but the mass is still there right. Wouldn't you still. We'll have a singularity even if it's spinning answer is yes potentially take a black hole and turn it into what we call naked singularity which is a singularity without basically soclean event horizon around it. Nobody knows what that would look like what it would be like. And if he would be any better or worse than having a black hole well well having a naked anything You know makes things more play. Yeah yeah that's why that's why paramount interested in their screenplay that's that's a spoof. Version of the the Bruce Willis movie negative. Can you guys think nobody knows if it would work. And nobody knows if it'd be better worse than just suffering through the destruction the original black hole but in theory might be possible to over spin the black hole and turn into okay. But we don't know that might be better or worse we don't know yet exactly but technically you hire me to destroy your black hole and then I turned into a naked singularity. I'M GONNA be invoicing you all right and I am sure we'll gladly pay that if restoring alive from your naked singularity and then the last idea actually came from a listener center really asking a question and you had another listener. Answer the question. Yeah another listener spontaneously wrote in with an idea for how to destroy Tori black holes and wanted to know if it would work and I thought Oh. I'm trying to figure out how we could destroy. Borough that's suspicious. I feel like guys are two people are playing you here Daniel. Maybe they're just a different. One is an alter ego the other one. When is the anti black hole version of no a James Casteel from Indiana? He wrote in asking about dark energy. Remember dark energy is expanding space and so it's essentially diluting. Everything so he wanted to know is dark energy happening inside black holes and if so could it like expand the space inside a black hole enough to basically shrink the density so you no longer have a black hole clever like eat the black hole from the inside out remember a black Hole Ada star from an inside outside. There's like SORTA turn it down strategy back self. Yeah like blow it up from the inside through space itself. Yeah exactly so great idea James and when we do want to build a black hole gun you are definitely invited to be on the task he can pull the trigger. You press the big red but But is is there something to this idea. Could you make dark energy gun or ray or bomb to expand the space inside inside of a black hole while they're a lot of problems with this idea. number one is. We don't understand dark. Energy is like at all. We think it's some property of space when you have various configurations of matter in the Universe it causes space to expand. But it's it's very actually very very weak. It's not very powerful at all. It only adds up to a big effect because space is so huge. The dark energy for example plays no role in the structure of our solar system because the gravity of our solar system is powerful enough to overcome become dark energy and so when it comes to a black hole dark energy is basically negligible right as new effect at all. Yeah but it is everywhere like love. Isn't it it's everywhere like like love but we don't actually know if there is dark energy inside a black hole because we don't know what dark energy is if it's a property of space itself then yeah there's some effect from dark energy inside a black hole but we don't know it. means the expansion of space anyways it would be much weaker than the gravity of the black hole together. dark energy is just one factor and to answer whether space is expanding after fold in dark energy to fold in the matter and radiation density of the universe than you crank it through general relativity the equations to discover whether or not you're getting expansion reason there's expansion out there in space is because dark energy is the only thing out there but if you have matter and energy like in a black hole all then you're not gonNA get expansion right but I guess the question is is the idea is that you know maybe one day we'll understand what dark energy is. Maybe one day we might be able to harness it or concentrated you know like if there is something out there in space in the universe. I can expand space. Maybe that's one way to kill by callers was like if we understand. Maybe we could make something that will expand the space inside of a black hole I lost count. Of How many maybes yes. We can build a dark energy gun. Give it to Bruce Willis then yeah the plans rock-solid which makes the point you make is reasonable all right is that there is something that can balanced gravity. We described earlier black holes or a runaway process because gravity takes over and eventually Wins because it's always attractive practive but you're right. We do know that there is something about gravity that can be repulsive and that's dark energy and so eventually if we understand it we might be able to manipulate it and cause a black Kohl's to fall apart from the inside using dark energy but there's a lot of maybes between now and then right all right so it sounds like our best ideas are fidget spinners. uh-huh Magical Unicorn is our base idea magical. Uniforms is definitely a good idea. Automated Magical Unicorn. Being written by Bruce Willis in love to save the universe. Welcome to our pitch. Thank thank you for coming to our pitch. We'll take those billions of dollars now. Thank you very true. We want a big advance. We're not delivering the script until the the end of the universe. All right. Well I guess I mean to answer the question. Can we story a black hole. It said it sounds like maybe not I mean it sounds like we have some wild called ideas but so far they seem like pretty inevitable part of the universe that will basically be around here forever and maybe we never go away. Yeah if I had to bet. On the most likely fate of the universe it would be a bunch of galaxies that collapsed into black holes separated by vast distances Mrs so it's pretty dark and bleak version of the future. Well we hope dead stimulated some thinking out there in you guys about what black holes are in whether they'll be around for a very long time or whether we could destroy one if we had the need to and whether or not it was a good idea to start a little black hole pet in your backyard. That's right and just in case. Save those fidget spinners. They might handy later and anybody out there with Magical Unicorn please get in touch. Yeah so this is a great question question and so if you guys have a question out there please send it to us. What's the email address Daniel questions at Daniel and horray dot com?

"What is that? If the cosmic anchor go at Karaj sale that Reggie had never thought avenues for it up until now. Open up that. Sure. Close the hatch. That should do it. Are you? Sure that thing's gonna hold us Mendy. Yes. Of course. I'm not sure IRAs, but this should keep us in one place long enough for us to see this black hole in action. Great. Whoa. Look at that circle of swirling, light guy rose not black holes were meant to be. Well, well, they are Mendis that circle of light. You're seeing is the leftover gas and dust from a star that it's just eaten. So as a black hole consumes a star rips it apart in all the material spins bins around the outside before finally plunges into the black holes event horizon in N Tarizi. That's right. The event horizon is the center of the black hole in the point at which the star disappears. Oh, I got it. It's like when you drain your bathtub, and then all of that dirt water finally disappears down the drain digs xactly and that leftover Starbust that circles around the outside of the event. Horizon is Colt an accretion diss ration- disc. Yeah, I'm just gonna call it Bob for simplicity's sake. So as all of this gas and other material from the star spins around the black hole it Tepes getting faster and faster and really really hot. Because of friction in king is the. Heat gets made when you rub two things together. Really really fat. Yeah. Like how you of your hands together when it's cold outside the heat your hands up. Okay. But how does this heat get? All right. Well, some of that heat energy gets converted or changed in two other types of energy like x Ray energy and light energy in this energy can travel for trillions and trillions of miles across the universe. Where it can then be picked up by our satellites and radio telescopes back on earth. Oh, yes. In guy Roz scientists actually have a special name for this the do. Yup. They call it a quasi is stellar object. Herb acqu as are for short and quasars are the brightest objects in the entire universe that makes total sense Mindy because from earth these super bright objects, even though they're millions of miles away. Well, they often look like stars in the night sky how into that's what we're looking at right now. That's right. I can't believe we're the first people to ever see a black hole. What do you mean? Because black holes don't reflect any light back into space. It's almost impossible for us to see them back on earth. They just get lost in the background kind of like when you had that black cat parade in the middle of the night. Yes, exactly. Like that you could hear them but headed see them against the black night sky. So if scientists have never actually seen a black hole before how do they even know there was one at the center of our own galaxy will the same way they find any black hole. He just watch. How the stars around it move on. How you said that black holes is specially supermassive black holes are really really heavy because of that they have a lot of. Grammy. Meaning that other objects orbit or circle it kind of like how earth and the other planets orbit the sun because of the sun's gravity. Yes. So what scientists look for our stars seem to be orbiting dark spot in space hot. So they're not seeing the black hole itself. They're just seeing how that black holes gravity is affecting the stars around. It got it. Now, you wanna see this bad voice setup. A star suck up a star Mindy. You know that can take hundreds of millions of years, right? I mean, I have to be in bed by eight PM. I know I know you need your beauty rest, but lucky for you..

"My sandwich. Plus in helps us slip the time machine through the space time continuum more easily less friction that way. Right. Just follow. My lead guy Roz in just slide through the man as from foot to foot like your ice skating. Just like me. Okay. You're big, Okay. okay. And sweat. And and and almost and twist and wish any. There we go. Cairo's? I've been buddy already. You're on the mad. Oh, it's fine. I've got my time traveling slippers on all ready. Wait, your time travelling let me just get these shoes off. Plug in the ordinate. Which black hole. Are we going to Mindy? You know, what I have no idea? Well, there are a lot. We could choose from. Yeah. I didn't even think about that. Well, yeah. Because black holes come in all shapes and sizes, and how heavy they are determines what kind of black hole is there are small medium and large black holes. That's right. And they all have special names like what? Well, the smallest black holes. We know of are called primordial black holes in scientists believe that these black holes are as small as a single atom in Adams are those teeny tiny, building blocks that make up everything including everything and these kinds of black holes are basically as small as a get. But remember Mindy black holes are really really heavy and these primordial black holes despite being the size of a single atom can weigh as. Much as a mountain all as heavy as amount. Wow. Okay. So what's next will mixed up are medium sized black holes, and they're called stellar black holes, and they're the most common type of black hole in the universe. So how big are they will Mindy? These black holes are about ten miles or eighteen kilometers wide. That's like a hundred seventy six football fields wide. Yeah. So pretty big but still much smaller than say city. Yeah. Might be smaller than a city. But if a single atom can be as heavy as amounting than how heavy are these black holes will these black holes can wake up to twenty times as much as our own sun. But that's not even as big as it gets many, holy still haven't talked about supermassive black holes supermassive black holes. Yeah. The name kind of gives it away. But these black holes are through per massive. They're about as big as our entire solar system. And typically they weigh about four million times as much as our son. I mean, isn't that my? What? Oh, sorry that was the sound of my mind blowing any who you were saying these supermassive black holes are usually found at the center of most galaxies and due to their enormous, gravity because the heavier something is the more gravity. It has exactly because of their gravity. They caused all the other stars in that galaxy to orbit for circle around like how the earth's gravity causes the moon to orbit around that. That's exactly right, but just on a much much bigger scale. So does that mean that the galaxy that we're in also has a supermassive black hole at the centre? Correctomundo Mindy our galaxy the Milky Way has a supermassive black hole right at the center called Sagittarius. A that's interesting because I'm. A sagittarius. Describe myself as having a type A personality Mindy. This has nothing to do with your horoscope. Really sure about that. No any who. So Sagittarius, hey, which coincidentally has nothing to do with your star signed is just a hop skip. And a twenty five thousand six hundred forty late year jump away old sounds like the place to be I guess, you should block those co-ordinates into the machine captain is that an eye patch. No, all right. Buckle your seatbelt here..

"Yeah. So we talk about how you can see a black hole. Like, a little black dot or black circle in this guy or something. So a black hole is so heavy that light can't escape it. Right. And that means that it doesn't reflect any light shine a flashlight on it. No. Like comes back. Right. You shine a spotlight on shine a laser on China anything on it. No, light comes back even has nice to we will. Won't bounce off. Does right. No, light reflects and also doesn't emit any light. Now, there's a tiny asterisk we should talk about later, which is called hawking radiation turns out black holes. Do give off a little bit of energy. But you can't really see it. So the point of view is seeing a black hole. It's basically invisibles just like a black circle. Right. So how could you possibly see that a black hole is there? Well, you know, I watched that movie interstellar, which I know could be whole topic of conversation. But that was your research for that. And I read the Wiki page for the black hole movie, which is classic seventies movie. Did you ever watch the movie? Yes, it did. In fact, I saw that movie a few weeks ago with my kids no way, I think it was supposed to be like a response to Star Wars. Yeah. And it's much weirder than Star Wars, according to compete. Yeah. It's like the first Disney movie ever to get a PG. My kids were like why did that show? Was this supposed to be good or is this educational this that huge part of my child? You know, it was like made a huge impression me you saw the black hole movie as a kid. You didn't see it? As again, you might have been the only one. Huge in Panama.

"Plus one five to three almost stopped reading there but you know you gotta sale the numbers and it's about one point six billion light years from earth so this is very very far away i included a picture here for us to look at but you can see how the quasar and the foreground because of its great gravitational distortion affects seems to create a lynn's image these distorted side effects of a galaxy that's in the background right behind it oh well but we should get to the next method because actually i think this is maybe the most interesting in one of the most conclusive methods that we have come up with so far to demonstrate not only the existence of black holes in the universe but some of the most violent black hole behaviors in the known universe and that is finally getting to a world where we can observe gravitational waves that's right so we already discussed the general relativity concept that mass distorts spacetime yeah as part of this einstein also predicted that we'd observe ripples in space time gravitational waves caused by some of the more extreme occurrences linked to massive accelerating objects like like a massive star being hit with god's pool cue what ripping up the fabric yeah or just just the shockwave the sound you know however you wanna you know interpreted just the violence of the act well you know one of the funny things in the last episode we mentioned the english you might call him a polymath john michelle who was one of the early people to write about the idea of something like a black hole in a thing that he posited that many people might not have been able to imagine at the time was the idea of ripples going through the earth the earth the like earthquakes could be caused by shock waves in the earth flexing up and down due to friction events and so you know it's hard for somebody to imagine how could there be ripples in the ground the ground is just solid you know i see waves in water but surely not in the ground take this the next step take this to ripples and waves emanating through the geometry of space time itself so what kind of violence would we be talking about it here so obviously god doesn't play pool so we can't go with the pool cue exam samples far as you know as well yes we doesn't play it in this universe in a way that we can observe it a but we can look to other cataclysmic events like supernova and colliding black holes now we were not able to observe any proof of this until nineteen seventy four and that's when a astronomers at arras cbo radio observatory in puerto rico discovered a binary pulsar and then it wasn't until twenty fifteen at astronomers using the lie go that's the laser interferometer gravitational wave observatory actually physically synced gravitational waves in knitted by two colliding black holes nearly one point three billion light years away billion light years yes so how could we detect something that far away what the whole setup here is really fascinating because when you when you look at pictures of it it does not look like a telescope they use special detectors in at the time two locations washington state and louisiana separated this way across the you know a what three thousand kilometers in order to rule out localized distortion right so you wouldn't wanna rumble in one place to give you a false positive on gravitational waves so what these things looked like are to blind lshaped detectors with with the four kilometer long vacuum chambers essentially long tubes with lasers shining through them right calibrated to detect like just just minute motions to measure emotion ten thousand times smaller than an atomic nucleus the smallest measurement average tempted by science though and against his calibrated to to observe these oscillations caused by the most violent and cataclysmic events in the universe that are occurring millions or billions of light years away so both detectors picked up on the black hole emitted gravitational waves at the expected intervals dancing black holes in another galaxy and then the waves stop is the merger becomes absolute is the.

"Its massar at about fourteen point eight of our sons and the radiation coming from the sources omitted as this apparent black hole sucks matter off of the orbiting star like we were just talking about with the neutron star it sucks gas or matter off of that star in the matter swirls down into the gravity pit of this object heating up as it does and eventually heats to the point that it gives off x rays of course once that gas falls passed the event horizon presumably nothing more more is omitted it's stuck inside but you've so you've got these observations it's massive it's tiny it's invisible and it shoots radiation out into space as it appears to suck matter from neighboring bodies really really seems like a black hole but was it proof this was actually famously the subject of a bet between physicist stephen hawking who did plenty of his own important work on black holes and kip thorne in nineteen seventy four real quick kip thorne by the way not only physicist but executive producer of the two thousand fourteen film interstellar oh yeah the that was probably the the best black hole movie i've seen yeah and that's why right so he he tried to get them to like get the science right yes yeah say be accurate and make it look like a black hole would really look let's do some math yeah and they they did the math and that's a that's that's something that most people tend to to praise interstellar for is being the best depiction of a black hole in at least cinematic science fix oh as i've said on the show before my favorite thing about it is how it actually deals with time dilation effects of relativity yeah there's a lot to like about interstellar but coming back to that bed i'm sure you've heard about this before this is a famous bet in the history of physics astrophysics so thorne and hocking had this bet hawking was the pessimist thorn was the optimist while i guess depending on what you think you know regarding the nature of black thorn bet that cygnus x one would turn out to be a black hole hawking bet that it would not turn out to be a black hole and hawking was wrong by nineteen ninety hawking admitted that the evidence for x one's black hole status was so strong that he had to concede the bet so we live in a world now where astronomers astrophysicists almost totally convinced the black holes exist you can fly out into space in theory and you could fly right into them but they nevertheless remain tricky from an observational standpoint so i think now for the rest of the road we should try to explain in some of the ways that we can use to try to detect black holes in space yeah a thing that by its very definition cannot be seen cannot be seen directly of what are the ways in which we can observe their presence right because one of the very things that makes a black hole unique is that it neither emits or reflects detectable light of its own so how would we ever know if one exists well there are lots of indirect ways of detecting them and of course even though it doesn't emit light of its own that doesn't mean as necessarily dark because as we explained in the last episode their stuff going on around us and in fact we just touched on one example of this we of the idea of stuff falling into the black hole stuff being material being sucked into it yeah so black holes themselves are dark but from our perspective the region around the black hole can be anything but so imagine there's this region of space where we observe extremely hot high energy radiation you've got xrays spewing out all over the place what's going on on their while a good chances you've got a black hole with matter falling into it the matter gets heated up to hundreds of millions of degrees and produces all these kinds of powerful radiation that are visible from earth until it passes that threshold however and falls into the black hole after which it emits nothing to revisit what we the example i brought up.

"black hole" Discussed on Stuff To Blow Your Mind

"Made me think about a one of the videos we watch from the world or will you were there at the event but one that i watched from the world science festival this year had a astrophysicist ship mon talking about black holes and he said quote what happens in the black hole stays in the black yeah i like that that that that oftentimes you see the especially the more modern physicists tooth who've written about black holes they tend to have a sense of humor regarding their nature yeah yeah i think that's generally true like they don't get all well i mean so here's what you can contrast that lighthearted approach with apparently some frenchspeaking astro physicists took to calling the schwartz shields fear the sphere catastrophe the sphere that's a hard thing to say sphere catastrophe i like the idea of this is being the guard french version of events horizon yeah yeah i'd pay to see that i hope it's still have same neil now we go the gerard depardieu instead oh yeah okay i it would be it would be a great version of event horizon where every scene they have fresh baked bread yes now one thing that's worth noting about this fear of doom the the schwartz shields fear or the sphere catastrophe it's not actually the same as the central object the black hole itself an example given marsha partouche ex black hole our son is about one point four million kilometers wide if a star the massive our son were compressed down to a point the sphere catastrophe surrounding it would be less than six kilometers across if the mass of ten sons were reduced to appoint like volume its sphere catastrophe would be about sixty kilometers wide and as we mentioned earlier if our son were suddenly shrink down to that size objects far outside this fear would not suddenly be like sucked in or torn apart the planets would continue orbiting just like they orbit the sun only it's only much closer that things would really go crazy but here's a really important point that we need to drive home at this stage even after schwartz shielded done these these calculations most physicists and astronomers did not believe.

"Is nothing right it doesn't really matter so yeah i think that's a huge focus and we need new tools like regulators any new tools to measure this sort of space but that's where i would put my focus i would not go into that interoperability side of things because we're dealing with black holes they suck everything in the key to success is avoiding that black hole and to have an inforce connection again you can theoretically think about it as i did and i've throwing myself in sports you come at your this framework of the microsoft all the sort of stuff and interoperability and in trying to break in like oh yeah they have data portability and you forget that these are fundamentally different markets are not platforms they are black holes they're not sturdy structures and you are enforced board ability goes both ways if data flows one way it falls back the other and in the long run it's sort of like taking that search idea where google being bigger they get the greater feedback loop and just increases their lead and it's sort of like federalizing it across a whole bunch of networks i mean that was the benefits facebook got from their mistake that we've talked about the context of cambridge and what are the scandal to share all this data they were sharing data and they're getting data right back in and if you have a central player that is doing his data exchanges with everyone else in the ecosystem who wins in the end the central plains so i'm with you in terms of would be very difficult to not be with you in terms of like okay let's get smarter about how we approach this going forward that being said we have this black hole that's two black holes three black holes it's a very big black hole i take your point about the data portability and these broad regulations and this is definitely one of the places where i've evolved as a result of a lack conversations over the past whatever number of episodes it is and your point around gdp like it's come to pass that being said this is a company that is triple black hole there is nowhere else that has anywhere near as much insight on the relationships that human beings have between each other like is there.

"Was that black hole just burp well kind of i think what we just saw was the black hole ejecting some of that stardust back into the universe and it didn't even say excuse me well it doesn't happen that often mindy only once every hundred million years or so still no excuse for bad manners well in the grand scheme of things mindy these little cosmic burps are happening all the time all around us in fact earlier this year scientists from the university of colorado will they saw supermassive black hole in a nearby galaxy burp not once but twice really wear in a galaxy about eight hundred million light years away called sd s s j one three five four plus one three two seven and it couldn't have come up with a catchier name for it oh they have one they call it shea one three five four for short right so how did these scientists either black hole birth well they did it using two fairy special telescopes the hubble space telescope oh i know hubble orbit around the earth and used to take pictures didn't galaxies that's right they also used another telescope called the shandra x ray observatory and that telescope can detect some of the energy given off by those quasars we talked about before the light in x ray energy these supermassive black holes give up when their second up stars right and when these researchers pointed their telescopes toward this quasar they sought to bubbles of gas coming from the black hole one had traveled about three thousand light years away from the center of the black hole in the other had moved out about thirty thousand light years from the black hole so what does that mean well.

"Yes exactly like that you could hear them but headed see them against the black night sky so if scientists have never actually seen a black hole before how do they even know there was one at the center of our own galaxy will the same way they find any black hole he just watch how the stars around it move how you said that black holes especially supermassive black holes are really really heavy because of that they have a lot of gravity meaning that other objects orbit or circle it kind of like how earth and the other planets orbit the sun because of the sun's gravity yes so what scientists look for our stars that seemed to be orbiting dark spot in space hot so they're not seeing the black hole itself they're just seeing how that black holes gravity is affecting the stars around it you got it now you wanna see this bad voice second a star suck up a star mindy you know that can take hundreds of millions of years right i mean i have to be in bed by eight pm i know i know you need your beauty rest but lucky for you we are in a time machine all i have to do is push a couple of buttons here whole of buell ever thank you not okay.

"I think you mean smooth is manny's i can't believe it's not butter believe at geyer is all right just opened up the blinds here so we can see the black hole with our fall the screen goal messed up these things open evenly newish shouldn't have put mini blinds in this thing what the what was that the time machine is somehow still moving i think the gravity from the black hole dragging us in hey he don't panic quickly mindy before we get stretched out like a piece of spaghetti think i'm we i know a one second to grab the downstairs downstairs this time she doesn't lords the what is that if the cosmic anchor years ago at that raj sale that reggie had never thought avenues for it up until now you open up that here hurrying close behalf that should do it are you sure that thing's gonna hold us mendy yes of course i'm not sure iras but this should keep us in one place long enough for us to see this black hole in action great whoa look at that circle of swirling light guy rose not black holes remain to be well why won't they arm indeed vet circle of light you're seeing is the leftover gas and dust from a star that it's just eaten so as a black hole consumes a star rips it apart in all the material spins spins around the outside before finally plunges into the black holes if vent horizon in enteritis that's right the event horizon is the center of the black hole in the point at which the star disappears i got it it's like when you drain your bathtub and then all of that dirt water finally disappears down the drain.

"Plant earth and some people have actually proposed that as one way far the future to move the earth if we're faced with a astronomical catastrophe if the sun begins to increase in size okay well let's move right along to the next listener phone call mike my question is why is it that you have giant star war coopting agreeing by black hole why is it that uh or they collapse that gravity is not great enough to stop the light from escaping them but after they collapse and create a black hole that gravity is too great to escape when uh before and after the matter the same or even because some ethics group's during supernova kroger question is why is gravity greater afterwards when there is no increase maths uh well we ask y you ask a very interesting question it turns out that the mass before and after the collapse is the same same so if you're a very far distance from a star this dying and this star is collapsing into a black hole that gravity that you feel from a large distance is the same it doesn't change at all however as you get closer to the blackhall then of course he can start to see distortions first of all even far from the black hole light will bend light will band as it goes around amasses start as it collapses but then after the collapse it turns out that light inside the black hole cannot escape but light from the outside can very easily whip around the black hole and.

"Gather an image that also fits our telescope measurements different types of images have very distinctive sets a puzzle so what happens when we take the same data but we use differ sets a puzzle pieces to reconstruct the so let'si start with black holes black hole image stimulation puzzle pieces okaythis looks reasonable this looks like expect a black hole but did we just get it because we feted little pieces of black holes russian images another set a puzzle pieces from astronomical non black hole objects okay hey we get a sigler looking image and then how about pieces every day just like the images take with your own personal camera great we see the same image when we get the same image from all different sets a puzzle pieces then we can start to become more confident that the image assumptions were making or by seen the final image we get too much another thing we can do is take the same set of puzzle pieces such as the ones derive from every day images and use it reconstruct many different kinds of source so simulations we pretend the black hole looks like astronomic mom black hole objects walls every day images like the elephant in the center of a galaxy when the of her on the bottom look similar to the simulations truth image on top start to become more confident in our algorithms andi just really want to emphasize here that all these pictures were created by piecing together little piece.
