"casimir effect" Discussed on SpaceTime with Stuart Gary

"Galaxies up to twelve billion light years away providing them with insights into the universe when it was just a fraction of its current age quals are among the brightest objects in the cosmos their powerful beams of energy generated by being ripped apart as it falls into a supermassive black hole as this quasar light pass through the galaxies. Specific wavelengths are absorbed by the gas resulting in an absorption spectrum telling scientists about the chemical composition of that gas but unexpectedly weapon colleagues noticed that the fine structure constant pete be different depending on which direction they were looking Web says. It appears to be getting stronger in one direction waker. In the other webs initial observations use the giant tin made a kick telescopes in Hawaii in order to eliminate any equipment aberrations with a telescope. The office collected data from a second observatory. The very large telescope veal t in Chile's hired a comma desert the veil to looked at a different part of the sky but it came out with findings consistent with kick showing the same rate of change and in the same direction as astronomers look at more and more distant objects in space. They're also looking back further in time. So we've been colleagues looked at even more distant. Quasars some thirteen billion light years away in never before undertaking observation the authors Caridad for measurements of the fine structure constant along the one line of sight to Quasar now individually. These for measurements. Didn't provide any conclusive answer as to whether or not they really was any perceptible changes in the electromagnetic force. However when combined with other observations undertaken by other scientists unrelated to Web's work the differences in the fine structure constant became evident. They found hints that the fine structure constant really wants different in certain regions of the universe the observations add to evidence that electromagnetism seems to be gradually increasing strength when looking back in one direction of distances of twelve billion light is while looking back over the same distance but in the opposite direction shows an apparent decrease in strength and yet in all other directions the fine structure constant remains just that constant. Hey you may recall that. Last month on Space. Time we reported on the work of Constantinople Migas from the University of Bonn his observations reported in the journalists Ron in the and astrophysics suggested that the universe is expanding at different rates in different directions. Astronomers generally agree that the universe that with the Big Bang about thirteen point eight billion years ago and it's been continuously expanding the since that rate of expansion appears to be accelerating judicial mysterious force called tack energy but that change in the red expansion still a piece to be the same in all directions. Migos research examined the relationship between the temperature of hot gases providing a galaxy cluster and the amount of x Rays. It produces known as the cost is minority. The higher the temperature the gas in the cluster. The high the x Ray luminosity is and so once the temperature of the classic guests can be measured the x Ray Lewis. Manati can be estimated. And He's where it gets interesting cost of the same temperature and located at similar distance. Should it be similarly bright? But that's not what they observed instead Miguel's colleagues or clusters with the same properties and with similar temperatures which appear to be less bright than what we would expect in one direction to the sky and brighter than expected in another direction and the difference was quite significant around thirty percent even more interesting. These differences want random but they had a very clear patent depending on the direction of the sky. Observing web says if the fine structure constant really does vary not just with time it also space that would require a major rethink of quantum mechanics and our standard model of particle physics. He says if the fine structure concert is different in different parts of the universe then that could mean different properties for chemicals and even biology according to web a full percent change in the fine structure constant would mean differences in the production of elements which would affect our stars burn and change the production of heavy elements such as those needed for the formation of life. What knew about the work that we put it too much. I am rich. All people want to think in terms of distance granted since away from all much closer to the Big Bang in time we pushed it right back into the universe is being pushed pool. We've gone into the infrared part of the spectrum for the first time which is allow us to do this. Before we had lots of observations our observations were all banned. Stop below redshift a tree. We've now we've got measurements from five dollars out to sentence. Well that means in terms of look time so the universe is about thirteen point. Eight billion years old according to the Standard Model. We've come within about eight hundred million years within about more point the is of the big bend. We've come back very early now with these observations. Then we've combine these observations. There is only one Chrysler in Sun Saddam's his Labor four measurements along the line of sight and those four measurements we've combined with a bunch of measurements previously closer to us in time. If you I and then look to see what happens to the directional signal the walls already hinted the data and the Council cow away. You know the NATO the points that consisted by themselves through anything it's still tend to push me to tantalizing but we got the same directionality and the it doesn't is certainly these. New Measurement certainly do not conflict with the suggestion that could be a direction not to the universe in fact a directionality signal is preferred of Nanda rationality. When you take the date say as a whole so. That's what new we've got. We've got measurements which go much earlier. Tomo distant from a concept to the time and they continue to support the idea of his notion that there could be a direction novelty in the laws of physics crack for new. So what this is telling us. Is that if you look in one direction. The value the fine structure constant is different to what it is in another direction. And if you look in other directions it matches what the existing figures for the fine structure constant Dr Ryan and the interesting thing is we have a new aspect of this since we lost little time ago. That addicted actually. Yeah I know time flies. Yeah the other interesting thing is that they've been a bunch of emission. Snow this nick. Nick measurement is the punch their measurements involving the cosmic microwave background the oak the flow of loss under the Galaxy. Supernova measurements in the McKenna's observation x ray emission from galaxy clusters and so forth. There's a bunch of other types of rations which completely independent of the of work on during the fine structure constant directing buffalo's physics but involve distribution of matter and these things also suggest the direction of the house individually each one none of them especially contending although statistically significant to some level but they all seem to line over sky within the arrows. There's still big but it's a very interesting situation. Now there's a chocolate it's a huge cosmic conspiracy or cosmic fluke and which is just one of those things but on the other hand something that really does need storing there. Is this apparent coincidence between a bunch of different measurements and the fine structure one which we originally published back in two thousand and first of all. We suggested that there was sort of that since then. All these other takes points being added so it's a really interesting situation. The fact that these things are happening using different methods of observation that's significant because if you're getting the same results using the same method then that's one thing but if you're getting the same sort of results the same observations by using different methods. That's actually very significant that starts to become something needs. Urgent Investigation Shirley. Yeah the paper. A while back by Greek authors of pulling together assessed I have a whole the statistical significance and it was looking pretty compelling but suddenly statistically significance that we up to the three sigma level yet or something like that well whereabout three sigma. We've just our amish. Wow and individually. Most of these are about that but you know the kind of the gold standard. If you like is is often taken. Us FIVE-SET YES when we're up to five six with this with this collection of measurement or not. I don't know I haven't looked into that on practice completely on the work that I'm doing which is trying to get this measurements. I can find structure constant. And we're the IT's actually pretty. Maybe about Muslim that for our listeners. Five Sigma was enough to give us. The Higgs bows on being. There is existing is being real. So you're obviously very close. It's an important point in this research. You're right five. Six is what got people convinced about. Expose on getting their luckily. There's some fantastic new instrumentation coming along and new facilities which means this means that we really can improve the data. He just takes time a lot of efforts that new instrument on the European supplements few Bart which has a new means of calibrating data. It's the data was precise. The new data is far more precise. Data's coming alone. We're getting better measurements. A COUPLE OF MONTHS BACK. We actually had time to make new measurements on all four. Voc's once this was unprecedented acting week. All for eighty two Tokyo were hooked up by optical fiber and each optical fiber was then brought together into one instrument to observe one Quasar to get a very high signal to noise good signal on that one craze. We've got that day to the observations with successful. We working on that at the moment we have announced yet. But that's coming. Just what one of the new things coming the national? The we're talking about came from another instrument on the OT X. shooter which is an infrared instrument infrared observations of this sort of been catching up with the optical ones. It's hard to build these high high precision high sensitivity instruments in the parade but the technology has called venture investor. That's what this new papers. About infrared measurement and go right back to within eight years that they explain the fine structure constant to us is a dimension ratio three quantities. It involves planks constant the speed of light and the charge on the electron and it's a dimension ratio involving those three quantities. The fact that is mentioned less has no units is very important because it means is more fundamental than a quantity like for example the speed of light which mentions so. This is the source of quantity that people like me focus on because she needs the units to make the measurement settle is the number of physicists. Used to Kerama tries to provide a measure of the strength of the electromagnetic force. There are four forces that we know about electromagnetism and gravity and then the two forces that act inside atoms the weak force and so it turns out that electro-magnetic force by the fine structure constantly the one that we can perhaps most easily make measurements all. And it's a constant which means it should be the same everywhere and this research is showing that there's a growing possibility that it's not that really is GonNa be affecting the foundation stones of our understanding of physics. That's right the sixty we've using for a very long time based on the assumption that the laws of physics of the same throughout the history of the universe that the same everywhere. If you take unsigned Syria. Gravity for example. It's based on. What's given the unstuck equivalence principle? Which states that? The Laws of physics always kind of thing that assumption makes it easier for them to build equations which gives us predicted power amish described the observations that night at the universe us without those assumptions. Everything gets very much harder. It's very appealing to have these simplifications built into standard models of physics but since if occasion is necessarily of the real universe it may be. It may not be a modern theories. String theory is permits by have that option built into them but the fundamental constants should vary put. It might be slightly differently in these new series of everything that nothing that stops with demento constantly changing nothing fundamental to stop changing and so many theoreticians actually expect that at some level we to see sort of changes and constructed new theoretical models to describe how the standard model does have its problems. It can't explain dark energy and it can't explain that matter at least not yet. That's got to be a hint that has to be new physics beyond what we know. I would have that. Everyone would agree with that statement. You're right the standard model of cosmology works very well. How if and only if most of the energy content of the universe is not in the form of protons neutrons electrons the stuff that we had it has to be in the form of energy and matter as well without those assumptions. You can't make the standard both work so there is certainly something new that we don't know about the model is wrong or these things stock a g dark matter do exist for something at some point. We'll keep dark. Energy couldn't just be a example of the CASIMIR effect on a cosmic scale and dot matter isn't just a new type of Neutrino that we haven't discovered yet. Or maybe it isn't. Maybe there is an axiom. Although the evidence doesn't seem to point to that people keep on placing upper limit some different candidates Sadat politics and the trouble is that you know even when you add up all of the upper limits. You can't quite get to the amount of dot master that you need to explain. The observations of economic see rotation cuts and various other teams rate. Yeah seventy dollars off found yet. There's lots of candidates. I guess most people would regard the mats and not as the worst mystery be like talking to g is because they really don't know go is Really don't have a coup as to what talking G is on the other hand it. He's in support of the sound. Will Idiots fascinating? The Standard Model has so many incredible successes and works so very well in many different ways.

"Now, I'd like to introduce our very special guest today. Once again, we have with us professor j Richard Gott the third he's a professor at Princeton University. And he's the author of a book called time travel in Einstein's universe. The physical possibilities of travel through time. Now, just remember that we're not talking about some inventor in a laboratory in his basement creating a time machine by which you can race certain rather embarrassing events in your history. We are in fact, talking about hard physics. We're talking about perhaps one day a civilization much more advanced than ours are perhaps maybe even are descendants thousands of years from now may have the ability to manipulate the energy of a star in which case they may be able to create a time machine capable of changing the past. And so the question is is time. Travel possible. Given the fact that there are all sorts of horrible paradoxes, you can get if you go backwards in time, for example, and shoot your parents before you're born. So once again today, our guest is professor j Richard Gott third professor at Princeton University. And we are talking about time machines and time travel. The first question for you. Professor God is how did you first get interested in physics? Well, I got interested in the strana me when I was about eight years old I belong to a stargazer group that was organized by junior astronomical society. And so I did telescope and as trying to me was a hobby of mine and in high school, and when I became interested in physics in high school and so forth. I I later decided to take my physics and work on astrophysics because that had always been a hobby of particular interest to me, and was there anything about the remains of the stars of anything about for example, looking for intelligent life in outer space or are wondering where the universe came from was there anything specific about astronomy that fascinated you? Well, I was particularly interested in the big bang theory. At that time. This is a bet before Penzance and Wilson discovered the cosmic microwave background radiation. So I was always a fan of the big bang theory versus the as opposed to the steady state theory. And I understand today your -ffiliated with the Intel science talent search or formerly known as the Westinghouse science talent search so tell us a little bit about your experience judging high school kids well for many years, I was the judge had chairman of the judges for the first Westinghouse. And then it's now sponsored by Intel Intel talent search in. This is a wonderful fives competition, that's the oldest and most prestigious competition for a high school didn't since signs in the country and five of its winters. Have gone on to win Nobel prizes. So it's a wonderful contest and ask you to do a piece of real research into Mitchell research, just like you would write a research paper and so forth. So unlike a test of some sort it's really you just try research, and we look at your research. So it's it's kind of like if you're a baseball camp, you know, you could you could test people out, but I've seen how fast they ran down to first base. That would give you some idea of how they might play baseball. But baseball scout would tell you that it's really scouting for the major leagues you really wanna see people actually play baseball. So this gives Dinsdale chance to do real research projects, which are fine and many people that enter this contest, they fall in love with doing research and for the rest of their lives and many of the winners of this contest of gone onto wonderful. Careers in science. So I would encourage people to apply for forty. Winter's come to Washington each year, and they give out very large scholar college scholarships. And it's a very exciting thing cannot let's talk about time travel in particular. There's a movie hitting the silver screen right now called Terminator three where killer robots from the future come back to harass in the past. So which started your romance with time machines because in the area of physics most physicists tend to at least in the old days scoff at the whole notion of going backwards in time. Well, I got interested in time travel by exploring some solutions to Anton equation. Einstein developed his theory of general relativity, which is his theory of curved based time to explain gravity, and we take this theory, very seriously. Because when he when he finally solve the equations for this nineteen fifteen they made prediction predictions about light bending, or is it would pass near the sign, and these are checked experimentally, and Einstein was found to be right and Nitin was found to be wrong. So since then people have been interested in exploring exact solutions to and fans equations, and you've heard of probably the most famous one is the black hole solution. That's the exact solution to an equation. So we take black hole seriously. Even though they're quite extraordinary objects because they do solve and Dan's equations of gravity, so hours in I got interested in cosmic strings. These are theoretical object. That are dance threads of energy leftover after the big bang that are predicted in about half the theories of unified particle physics and early universe. We we haven't found them yet. But we are searching for them. And I found an exact solution for a one cosmic Strang what the geometry around one cosmic string would look like and William Hiscock found the same solution independently of Maine to were given joint credit for this pollution dance dance equation. And then later I investigated to moving cosmic strings what an exact solution would look like if two strings were to pass each other. And I did found an exact solution for that JAMA tree. And it turned out that if the strings were moving fast enough, but still slower than the speed of light that this was a solution. That would allow you to circle around the cosmic strings and arrived back home. Before you started. So it would allow time travel to the past and there've been a number of general relativity solutions like this. The first one was found famous mathematician, Kurt girdle in nineteen forty nine rotating universe. But we don't live in that kind of universe. But it's an interesting solution to the equation that allows time travel to the past. And if there's one pollution like that there could be others, and then Kip Thorne and his associates found wormhole solutions that allowed time travel to the past. So it's extremely interesting that these equations of and fans of general relativity themselves, and this is our best theory of gravity at the time. Famed allows pollutions that allow time travel to the past. So I got interested in it just from trying to understand and stands equations with objects that we were interested in. Okay, now, let's talk about the move. Everyone likes the movies and people have seen a lot of movies where we have black holes that are rotating very rapidly. Right. And according to mathematician, ROY Carr in nineteen sixty three he did find it solution of Einstein's equations where if you pass through the ring not a point. But a ring spinning very rapidly you'd wind up on a parallel universe, perhaps even a distant point in time. So could you elaborate about what happens if you haven't forbid fall through a black hole and make it quote to the other side, unquote? Well, this was an unperturbed Blackhall is the solution to and fans equations, and this is one that's left alone complete lane, you ignore the effect of hawking radiation, which we can mention later, but this first solution for a rotating black holes show that if you traveled inside the black hole instead of a singular point in the center, you would find as. You said a rings thing you Larry if you pass through the ring, you could navigate your spaceship in such a way that you could travel back in time. And then after leaving this region, you could go and pop out into another universe sorta like getting on an elevator store and going up to the first going from the first Florida the second, and you could get out on the second floor universe than later. You could go out and go up to the third floor university over, but there is no getting back to the first floor. Once you went in there rotating black hole. It was not possible to come back outside and brag to your friends about your ventures. But quite interestingly, there was a region of time travel that was trapped inside the rotating Blackhall incurs pollution. Okay. Now, let's say you go through the black hole and you're not crushed by gravity because it's gravity spread. Got a little bit throughout the ring. However, there are some naysayers who say, wait a minute. Let's not go so fast. And you mentioned that the black hole was not perturbed. So could you tell us a little bit about some of the naysayers who say that maybe you can't make it quite all the way through that black hole. Well, the trouble is that they when you pass inside the black hole and you pass into the region of time travel. If you're looking back outside you're watching the you're saying the history of the external universe is you're passing outside and in in Mr. car solution as you pass the end of the region of time travel. You would be able to see the entire future history of the universe pass before your eyes. Now, you might say, well, this is a good thing. Very interesting for historians. You get to see a whole future history of the universe in a finite amount of time. But the trouble is those photons coming in would be infinitely blue shifted and and. Become instead of visible so times, they would become ultraviolet than gamma Ray photon. So these could kill you. You have to pass them on your way into the region of time travel. Other effects need to be considered to like the fact that the black hole may evaporate. Would it be expected to evaporate from hawking radiation, which cuts off your view of the very late history of the universe? But also in other effects were quantum effects on the inside of the black hole. So the situation is that some people have explored this situation, Mr. berko for one Amos Ori, and they have found that that you traveling to the region of time travel, you you would probably pass this thing you Larry the the the curvature of FaceTime would would would become infinite. However, it takes a very brief amount of time for this to occur. So the singularity may be maybe weak in the sense that it that it may not tear your body completely apart and also quantum effects would be expected to knock out. Any 0's and the solution? So the trouble is that we don't really know exactly what happens to you. When you go inside a rotating black hole, and we we may need of quantum gravity to explain this. We know how gravity behaves on macroscopic ordinary scales. Einstein's theory gives us a wonderful and very well. Check theory of that. But we don't know how gravity behaves on microscopic scales. And to understand what would really happen going into a black hole. We may need to know that. Okay. Well, we have had on this radio show several people who work in superstring theory. Like, I do and look at these things. However, the theory is not very well developed yet. So let's ask a hypothetical question. Let's say you are an advanced civilization. Like we see in the movies an advanced civilization that can move planets and move stars. I mean, really powerful. Technology. We're having here now with that kind of technology. Do you think that someone could go through the ring to perhaps a parallel universe or perhaps in time or is just simply not known in terms of what we know about quantum gravity or do most people think Bah, humbug, you just can't do it. Well, I think that the if you're using my cosmic strings, what is duper civilization would try to do is find a loop of cosmic strings cosmic strings, either infinite they have no answer either their infinite if we found them either infinite or they come in loop things think of spaghetti or spaghetti O's. Find one of the spaghetti O's one of the loop manipulated. So that it collapses vow large factor, and you could you could arrange it with your massive spaceship flying around it. So that the two sides of the string would pass each other at the speed required to make a time. Machine. But I was able to show in that case. This would also be in grave danger of forming a black hole. In fact, it would likely form a black hole. So the region of time travel would likely be trapped inside just as we've talked about in that rotating black. Okay. So I think one thing they have sizes that. These are projects that really this. Loop would weigh half the mass of our own galaxy. So we're talking about projects that really only a super civilization could attempt. But as you say, we're interested in finding out whether a civilization with arbitrarily large powers, but but still operating under the laws of physics could do it. And I think probably until we really get a theory of quantum gravity. We can't say for sure whether they would succeed or not. Okay. Now, let's talk about the wormhole because on Star Trek, they simply zapped through wormholes to the other side of the galaxy. Now, if you had a black hole there is a problem there. And that is it's a one way ticket is basically a Roach motel you go in and you never check out again. A one way trip. However, these wormholes that we see on Star Trek are transversal, you go back and forth back and forth. It's like taking a Sunday drive right through a wormhole. So tell us a little bit about wormholes and whether or not they're practical. Well, the worm. Oh, God idea got started. When Carl Sagan who was writing this book contact with later became a famous movie he wanted to use a wormhole to get Jodie Foster from one part of the galaxy to another and so he called up his friend, Kip Thorne, instead, listen, I I'd like to get the physics right here. What about the physics the warm halt? So aren't in is associates investigated this and they found out that in order to transverse it back and forth. You had the prophet open with what we call negative, energy density stuff. This is stuff that weighs less than zero. In other words, you'd have to add mass to this to get back to zero it does it weighs less than zero. Well, that's very strange stuff. But you might say, well, that's strange. You wouldn't expect to find that? But occurs we do know a quantum mechanical sacked the Casimir. Effect which is one where if you take two parallel metal can conducting plates, and you put them very close together the quantum vacuum state in between the two plates, actually acquires a negative energy density weighs less than zero. So Kempthorne was proposing and and and and somewhere effects occur in and connected with hawking radiation and black holes and so forth. So we know of quantum effects that can induce negative energy density state. So what kept soaring proposed to do was to cover the mouth of each wormhole with a conducting plate and put them close to each other in the wormhole tunnel tend to the man is ten centimeters apart. So they introduced a large negative energy density..

"In the lab so we've detected the casimir vacuum and it has a negative energy density so it's a quantum effect and that's what he was relying on there's also a slight negative energy dance today effect around black hold at slowly causes the black hole to evaporate this is the hawking radiation so the heartland hocking vacuum around a black hole has a slight negative energy density so i think that these are not as far fetched as people might at i think now every once in a while someone says that they've been able to create a design for a time machine that they can put in their garage now given the fact that we're talking about black holes we're talking to vowed tiny amounts of energy from the casimir effect don't you think that it's a little bit premature for these basement inventors to announce that they've created a time machine in their in their basement yeah absolutely the more mold solution would weigh about two hundred million solar masses the loop of string that i was talking about this might be a fraction of the massive our galaxy so this is this is not something you're going to be making in your garage but we're we're interested in these the theoretical possibility for them because to realize whether these things may may be possible we may have to learn about the laws of quantum gravity and this is the topic of great interest so they're they're a great thought experiment to explore physics in the extreme and of course einstein was talking about face ships traveling near the speed of light and ended up with equals mc squared which is at practical consequences yes i think so so in other words i guess we should not expect any any amateur inventor to come up with a time machine in their basement many times soon but now let's talk about the paradox is you get if you build a time machine if you could go backwards in time like what michael j fox did and monkey around with the past don't you thereby change the present in fact changed the president in a way which is logically impossible like for example if you go backwards in time it commit suicide how could you be alive could you just committed suicide in.

"And there's also the alcove beer drive we had miguel beer on the radio in fact and he mentioned said if you compress compress space and time in front of you then you could leap leap faster than the speed of light but of course as always drawbacks with that design as well right in fact there's always a drawback with these designs right well yes he the his his his war drive he was actually the referee on paper make it into a time machine so the the the star trek episodes that involved sometime traveled in the past rescue the whales and things like that they actually had some basis if you have a warp drive you could theoretically use it to make a time machine is as well right however there's always a catch and he mentioned to me that the fuel necessary to drive his work engine requires negative energy or negative matter and we haven't seen negative matter anywhere in our universe it would fall up rather than down and some people doubt that it even exists at all i think i'm i'm i'm more i'm more optimistic the negative energy that was using in his to to prop is wormhole mouths open was produced by the casimir effect this is a quantum effect the vacuum state that exists between two parallel plate and this is proposed like in nineteen forty eight but the the pressure effects associated with this casimir vacuum of actually been.
