FORA.tv the world is thinking The title of the book is Death by Black Hole inspired by the fact that any time this is on airplanes let's see if I know you astrophysics the outcome the questions that have questions or catastrophe question when life hands will the asteroid come up with well the universe and what will earth spin off its axis will the Aztec calendar destroy the earth is all there the boat on the necessity of people like death and mayhem so I'm article titled the book with that because of the whole chapter on how to die as you fall into black hole which I personally think it's kind of cool whip it up if you gotta go gotta go to so that's a new chapter called Mrs Betts one essay among one chapter among seven chapters under the title on the sub heading when the universe turns bad always the cosmos wants to kill us so just one of those ways you could die and for me that's what we think we like well yes it's that some like what that you would die that way what happens is the gravity of the black hole use the extreme as you can imagine light doesn't even escape its gravity is so extreme like traveling at the speed of light bright light just to put that in context if you want to escape the earth it's actually possible to do that country which grandparents all with a suitable goes up must come down this is not true well there's nothing your grandparents ever through that never came down but with rockets with high speed you can sense some things that never comes back for earth that's speed is seven miles per second we're going to escape velocity but if I throw something that Apple to it what love is not fast enough to come back so most of life experience tells you what goes up into seven miles per second is never comes back to go to the edge of the universe there ok so now turned on them on a black hole the escape velocity so high that you have speed of light isn't good enough so if light to think about the films coming out its black to fall when you're not coming out that a one way trip it so if you die this way you won't get to tell anyone how you died I it's a start but second as to fall in don't just die Creek you disappear you die long before to disappear as to fall in the gravity at your feet becomes rapidly greater than the gravity at your head now now it turns out as it's you stand on earth the fact is true under those conditions as well because your feet are closer to Earth center in the proper credit to goofy actually feel a stronger force of gravity but not by much because it feared oh five ft tall six feet tall and earth is like four thousand miles in radius that difference is not that great compared with the distance to the center of the earth black hole they're so small so compact that your height becomes it matters as you all when towards debacle so goofy start flowing faster than your bit to us that's a bad situation of the year don't really additionally each other feel good you know it's heavy you real stretch when you wake up morning initially it feels like a stretch for general relativity can you ok to have a job to cosmic joke but what happens is that stretched continues beyond comfort level and you reach a point we are going to call the tidal forces tights under body basic that of fortune so great that they exceed the inter molecular forces that bind your flesh and so the point comes when you smack into to pee likely to happen at the base of her store now your two pieces know it turned out I don't even ask about this but I have I got a whole chapter on the Titanic so it turns out you will survive that smell because below your waist while there are in court in four games there are no vital organs below your waist so it was so will stay alive for a little while ok it to bleed to death with this all happens much faster than would take to bleed to death so these two pieces then feel tidal forces they snapped into two pieces it in a snap again continue it in sixteen ten acre fight for treating your weight that so eventually it your head and multiple other parts and so that will continue until you are a stream of atoms descending toward the effects it turns out that's not the worst of it it turned out the fabric of space and taught almost down towards a black hole so the space to chew occupied up here he is larger than a space to occupy down here so in fact you're getting while you're getting stretched you're getting squeezed excluded from the fabric of space like toothpaste to it too now we have a word for that call speak edification the bed stop invented for just this purpose one thing more good editing which is having worked for ways to die right with a word if you kill someone else the word few different word if you kill yourself differ were to be killed by electricity that if it were to be all work for how the dock its unification too they go with in in addition to more exotic what digress to the question to answer sorry in addition to the more exotic ways to but you've also talked about more mundane was in fact more likely with is that truth that the impact of the most liberals spot up by cosmic catastrophe in the chapter as a whole other chapter called coming attractions asteroids this is a real issue this is something that one is headed for the Pacific but this time at the end of trading we would love a holiday and in prayer cool stuff to talk with this book right now to another we can do about it so I tell you we can do right so the typical office headed for the Pacific Ocean five hundred miles due west of Santa Monica which is of course south of here but um with QQ location and college for dimension we'll talk with you know cleaners MRI and a socialite talk about it now it this almost all the way is that far there is an asteroid discovered in December two thousand and four call puffs named for the Egyptian God of death and darkness it was named all week after the trajectory was identified to intersect that of her at the top in the case we would not have named to the office you name it might just end here so pretty some non threatening this one was headed towards Earth of puffs alright once you discover an asteroid you gotta wait a little while to get enough of a segment of its work to calculate what the full board will be to know if it will come in harm's way so we did that we the community I was when we got to this day so peeps if you're over thirty means people forgive say God keeps his people it's actually a whopping for this bright smile a little more than nothing right so we get the board turned out be the year twenty twenty nine the month of April the thirteenth of May Friday effects profits will come so close to her that will dip below are working to make patients at once and it is the size of the Rose Bowl to be the largest closest thing we've ever observed to come by her now of course a much bigger asteroid check out the Tigers we work around the top so this isn't in the era of observing the cousins with technology this to be the closest biggest thing will ever see come by now the work that we now have poured it on a certain enough because these things are hard to measure hard to get an exact distance or to sponsor it so we cannot tell you exactly where that trajectory will be we know what hit her we know be closer than the orbiting cent there is being rate to six hundred miles so because people the asteroid goes the middle of the key all it will hit the or thirteen years later it will hit the year fiber tomorrow so far km due west of Santa Monica it does matter where it goes that you know that most of the center if it goes through other places within the keyhole been no contact point shares further into the Pacific or closer towards plots North America yes it but because of the center it hits the Pacific Ocean just that it to the Pacific to a depth of three months at which point it explodes hitting the Pacific don't hold its three mile walk three miles that will send a tsunami wave outward from that location that's fifty feet up by store options don't like having holes stop this forty my own heart award all goes well you say this with commitments it collapses we were all high wall of water thank you fall back into the hole squashing against itself with such ferocity that Iran is it high into the atmosphere and fall back down to the ocean kept eating the ocean again you make every second time this cycle takes about fifty seconds you can calculate ok so here comes the first bombing the fifty seconds later comes the motion on so there you are on the beaches of Malibu tsunami comes in now auto like the tsunami hit Indonesia which was one way the twenty fifth to the shore this first one he knew he was the supply of water to exist so that the next wave actually socks back on it to create self soul this on the new legal in about a quarter mile the we have the sound effects person the road so I was in a quarter mile before get sucked back out for the next wave to come here's the problem whatever was there on the coastline is now brought back out to sea in the next tsunami brings it back to the shore all the million dollar homes in Malibu they get taken out to the sea bed and back but this time they are slightly different shape it so what happens is all call them ball be artificial stuff all the houses the factories they get churned into this up only two blocks Dex and laughed the entire west coast of North America so happy with that so about this big school so I set up thirteen years after twenty one that I miss pump up its April thirteen twenty twenty nine and it's a threat to kill it it will get hurt people thirteen twenty thirty six so tickets to a second the foreign press I don't have what I know you are right now that I didn't know my heart open with it though so bad but this begs the question was whether that way will be felt up in the Pacific rim but Japan cross wide can expect to fix farther from the impact zone so the wave of the low low but the wall feel to continue for about forty five minutes what we do what we do about it well marker tell her ok I have to pee the film did we start but you just did of joy primetime running away from that financial disaster it why is it that this is a flood we gotta run from the fourth the heartache that the Seaway the volcano I think in terms of the twenty first century people why we like stop it from happening in the first place what to read about what one with why we building tornado shelters rather than to have stopped the tornado ok we should think differently about the problems we face but it's parked in the chair for the chapters of ways for a plus to kill us right this in response to the people out there who say all earth is just perfect for my oh what a haven of all the universe just right I just lie every opportunity to try to kill us the salon to the public in a tornado after what does that according to the town of Red Robin but making sure did ten minutes later and consulting each year ok I got a problem anti God earth is bad for life so that he is the fossil record eighty nine percent of all species only and are now extinct that is not the signature of a planet that is in love with life what the we stopped to look at that making this up fortunate to get me started so yes what we do but Castro there people who look to see which one to hit them or someplace else from St while it might become an engineer and forgot how to deflect it ok actually the two camps of it there's that supper on Scott his old foe we've met that we know what they are we got the new slid open the silo take a nap not tear it down we are we that if we Americans are very good at blowing stuff up with this good at understanding with the pieces go after close to the day they cute that's just how that works so if you wanna call the store any USA you hit it with a new candidate splits into two I have to be back with two plates on it instead of just war you know like if you only have to go to smithereens Sophie will burn up in the atmosphere but you have no guarantee of that don't guarantee what stuff looks like after blows up so we took our little pony up a bit of difference of nemesis also but not so subtle office we can survive to be really beautiful of meteor shower do with it with the soppy and that they would be a warm night well in the saddle like the parts short pants it was a dislike to be toasting there will be toast slots you know this California you'll be asteroid impacts to like it might do for us right to become a turnaround has been somewhat biblical disaster going on out here the Flyers have it probably will when the locusts common in the fraud it off it the scope some really dope she likely wouldn't wake of the locusts I've really come out of it or not on plus has overseen a comedian joke about take credit for this job the comedian noted that all these disasters a carport all like happened in the rich neighborhoods right for neighbors never liked affected by these disaster so some cosmic were forced on network TV reported on the theme of the um but so do we get back to work so all the e better be for my money the more sensible thing to do is to deflect the top people working on to fortune scenarios right now the one that is if this is the opposite it's possibly determined to win the test tube really need to score well only the battery for second cup of the Cup with Becca Jessica go along profits come into effect so that reflection scenario is to give station to be look somewhat that right you come up to it and then use com or parking next to the statue that we know we use in part to sing some more orbit the yep our kids with um is very little easier to what was happening the parallel park it as another so so what happens if both the asteroid and the station the ways couple tons of forty me each have mutual gravitational attraction so they will want to deport each other the problem rapture rockets that prevent that from happening what's it going nutso to prevent it everytime you prevent it actually tolling the actual from its intended path that is a gravitational gravitational tractor if you get it early enough you know how to live by much we have to do is have it meets the keyhole that's all you don't want to go to the feel of it if you miss it one direction it to overshoot her to go to the direction you wonder if you are what if Jackson would drag it into the keyhole I would be bad don't want that to happen actually dragged into the keyhole if you would be on popular so hot that we the people working on that this the right time scale people are today will be a live band and we just need a reason to label thirty but to top it off the west of stress right now the super the gospel or so up so that's the best that tonight you know you've actually just described a scenario that appears and the current Americanism actual history state show cosmic collisions and that just because I have a sort of vested interest in a trance but just distract you from of black holes Masters for second you were involved in a really principal motivators and transforming it into a turn which is one of the vehicle for a regional conference in the country too but twenty per cent to touch I am but before anyone else has done that so disappointed one common process capture a planetarium you know there are many scientific disciplines that can boast of a facility that introduces the uninitiated public to the frontier can feel that you know what off select him as well use for us that's what quite like Netflix to museums are to have the fossil dinosaurs there by the way our talk like paleontology colleagues they don't like this at this our effort to counter the test with that never forgiven us for that um nevermind and that was the asteroid we would still be running under foot T Rex Cafe we were what servers Carmelo ancestors what stirs for T Rex two asteroids we think of them is that but the pry open new ecological niche to allow greater the experimentation of our favorites before turns against them find another way to kill to try to stop the planetarium its attendance was dropping while the tenets of the rest in his ear was rising sweet to stop and chat and it was getting cold and sleepy and dusty and was still disappointing up consolation when that's not the frontier of astrophysics and so we invest in future government although less money than what you guys for spending to be completely rebuilt how Academy erm our costs twenty three million dollars half of what you guys are spending and sold it build a building where we can leave me the bright green building or death very green the public's old Hamilton stuff but quarter in cycling through I'll check it out like it but we didn't get to the reef to decide if it was raining so to get soft ever needed so we rebuilt the facility and no instead of showing slides of pretty pictures of the universe we load up a supercomputer with a three dimensional data that we know that up with a soul system but still it is tradition in our galaxy gas clouds the distribution of galaxies in the universe below the top then get projectors on the dough that seamlessly marriage to have one continuous footprint and though you project a charity the room with a three dimensional data set on the go some old are you just work on earth asking what time of night is where my on the planet you're saying what platinum while and what Galaxy right now forty two pence and so now the entire universe this post and the attendant grew by a factor fun with it middle of one leaders can truly bring twenty first century a strong need to apply turn from two weeks for the kids yet I consider somewhat for tapas bars by its very first day was very geo center and that's fine it's ok to a point but he really was attractive moving frontier bash for physics you gotta change although I feel the world just by standing still so that's what we did get me to just listen to me at just this process of a car show his cosmic collisions every naturally we create for you the collision that took up the dinosaurs sixty five million years ago the new seat of what Brian was referring to concerned about suppose to do people the rate of profits into multiple little parts the energy is still there the energy of collision is still there it just doesn't make it to Earth's surface genetically with that punch into the ocean he turns up with the FSB heating the atmosphere so the concern is governed top of that happening this flashy can ignite sorts of things that separate topic enough for that by the way to know the spy satellite that shit you saw that in them my phone was ringing off the hook I said I'd get somewhere on time ok at all despite this the satellite before that this guy ok this happens all the top you dislike curious about it was a spy satellite somewhat fall out of stock they did not have this people today are so the war the worry is that my kids about this is borne out of control so with the Detroit do is be with you know Tomahawk the weapon up there to break into more pieces so that no large piece survived a trip down to the surface and have some form or discover all our treasure seekers in the spy satellite so that's what they wanted to break his will so that they were with him and the parting of pieces but what happened at what they call the K T boundary that renders the dinosaurs expect not only does that have stored with the size of Mount Everest plunge into the Yucatan Peninsula of course it was called that but that location of the air but the crater with fifty miles across cast millions of tons of Earth's crust into the stratosphere that was passed for debrief brains back down burning up flash fire in the far it's in the dating of the vegetation creating stop rising high into the stratosphere walking the earth preventing photosynthesis knocking out the base of the food chain in sending a way of extinction across the tree of life seventy percent all species honor when extinct because of that a new sound of that they like or are those can I get the car let it go so we recreate that for the show what's funny about it its results it will do so okay for my children then the funny thing is it really creeps out the adults kids love get on the video game cannot make it that every day the package the parents that can scare so we show that was another Collegians as well what was permissible shot with the times for scribbling you for children of the traditional way well actually the goddess or whatnot look at the oversold because the asteroid would be colliding in twenty miles per second which is way faster than the speed of sound the window cause I often look to watch that happen because it's way faster than the sound is making so if you were anywhere to have it you will have no idea it Wally Wood season explosion of fun it would be vaporized first to come then you go right but no details yet but a QB you be a prize at the ground zero of the impact that's the fastest way to go it around the side he would then be incinerated from the four fires if you were somewhere else on the earth no matter where you have actually just don't think it would supply with all the whole surface cleaner this oven temperatures our guests yet the oven temperature for hours plus I would say on what's right but not too much debt so that what would help people talk like that and understand what I get the words in the ghetto so it would help that she was the lead up to live in the nooks and crannies beneath the surface and fat modern biological investigation to her talents it may be the most of the final mass over is to be found beneath the surface and off our troops they will fight like creatures and things as they gotta get around walks for whatever that's worth but the final best of all of the bacteria Oldham also love the band has a lot more places to live when you have three dimensions to live the killing of two dimensions of Earth's surface that's how you can gain this with a total volume of our fine so that's the case that exasperated facts are that devastated live on the surface but you just wear while you know the ground dwellers crawl back out to be popular to serve his people and go go go from there
