Listen: Why are scientists suddenly preparing for an asteroid hitting Earth?
"Rod pile who is the off author of how many books ride, but it's pile book. Are you seriously wrote fifteen books? Wow, everybody. Yeah. Yeah. We all do, and obviously you have no life. But that's okay. The books are fascinating to say. The least all right now back we go to a topic that we've talked about many many times, and that is what is been considered by many people sort of science fiction. He kind of scenario the giant asteroid hitting earth. And what happens, and and the space folks are getting more serious about looking at this, aren't they? They are. And it's it's it's quickly. It's just a matter of time until it happens. Again, you don't have to pay more than drive a few hours east of their own ah to see what it looks like when a meteorite hits the earth or an asteroid hits here because it got meteor crater over there. So there's Nassar's the tracking along with the air force and various internationally sees as many of these nearer optics. They can which are the larger rocks or slinging neighborhood. That, you know, big cataclysmic happens every hundred billion years, or so I mean to, you know, make that sound casual it's a big deal. So they're running to drill last week along with FEMA and your space agency, a bunch of other agencies sort of practice, what their response would be one of these things were about to occur, and they created for this scenario for asteroid twenty nineteen PVC, which is estimated to be three hundred two thousand feet across. Unfortunately, when say did some of their tweets, they make it as clear as they might have that it was a fictional event. And the few people started flip out, and so what does a at asteroid well, three hundred thirty two thousand feet across. I mean, there's a big difference. Three times bigger. Let's say five hundred feet we'll sort of split the difference five six hundred feet. What does that do when it hits both in terms of the ocean and in terms of land? So if it was on land you get. A crater probably about a mile and across which is plenty big. That's a climate disruptor. You know, that's enough to really mess things up in terms of temperature and agriculture stuff 'cause you know, it doesn't take more than a couple of degrees. So you put that much dust and dirt and junk of the atmosphere. You got real problems of hits the ocean. Instead, you've got a bunch of water vapor, and potentially I suppose depending on the size and the of the media the depth of the ocean. You might have some some of the the solid mass of the ocean floor come up. So neither case you've got disrupted and potentially. So it's it's all bad. What can they do about? It. You have a meteor coming in and five hundred feet other than get the hell out of the way. If you know where it's gonna hit. What do you do with it? Well, the earlier you find them the early you can try and plan to intercept and this is a course of the course of the movies. You were talking about earlier about we go out there. And we knew could or kick it or redo it ever. We're gonna do probably not going to happen that way. But there is a mission called the blast redirect mission there dart at NASA sending up nearly twenty twenties which is just an impact or at the spacecraft. Swam into a very small asteroid gonna zurve to see how much that deflects trajectory that works in the future. Either. Use impact was like that. If you can catch them far enough out further away, they are smaller divert, you need to do to get them. Wait mirth or potentially even use something. The Russians are talking about doing experiment with a nuclear warhead because I got so many of them where they said it out and not blow up the asteroid. But but explode the warhead off to one side that would heat one side of the asteroid that offensive essentially propellant, Soma course for so two questions. I know we're limited in time. How big was the media? Ear that slammed into Zona meteoric crater. That one was something on the order of a hundred twenty feet across and larger ended effected the climate of the earth. I know that one was the biggest media craters only a few hundred feet across is not that big. So probably affected the regional area. Right. So the next question is if we're talking about a meteor couple of hundred few hundred feet across is not going to wipe us out. But it's going to disrupt a whole lot the climate at cetera. If you've got a meteor, several miles across is her son. Well, that's that's what you're talking about. With the the impact that took the dinosaurs down was sixty years ago that was on the order of of miles somewhere between seven miles maybe as many as fifty they just don't know. But if you've ever seen the aerial shot of that area, which has never been out to where I think it's kick skill stub. You know, it's a huge to impact crater. So. Yeah. That happens. We're big trouble because agriculture and livestock failed completely. All right. So when do we become the death star blowing up how big? How big a media is that we need for that that that would have to be something the size of small boon. So, you know, many hundreds or thousands of miles across that takes the planet out. But hopefully, you know, things happened to the Obama administration is they increase the funding for at least observing charting these. These large objects by ten factor ten times. So one of the big goals is to get some morbid observatories up it's more ground based observing that can track smaller objects and more accurately track larger ones than once. We know where they are predictor today trajectories better, we know how to go intercept them with where a lot of money for that. And since we've been talking about this over the years. Scientists have actually gotten much more serious about this. This is become real stuff hasn't it? It has. I think part of that was just looking at seeing how many of these things out they're beginning to see what trajectory that were taking and looking back to the delight of history and saying that looks like a crater. Hey that looks like a crater to more of it. You can really see these things easier and putting into together and realize something that's just an edible. And we're going to figure out how to cope"
