Neil DeGrasse Tyson discusses Death by Black Hole .
Whether discussing the universe's origins as host of NOVA's "scienceNOW" or asserting that Pluto is a not a planet on "The Colbert Report," astrophysicist Neil deGrasse Tyson translates the universe's complexities for a broad audience.
Known as the great explainer of all things cosmic, Tyson first became known in the astronomy community by lecturing on the subject at the age of fifteen. He is currently the director of New York's Hayden Planetarium at the American Museum of Natural History, where he also teaches. Tyson has written seven popular books including the bestselling Death by Black Hole and the memoir The Sky Is Not The Limit.
His professional research explores star formation, dwarf galaxies, exploding stars, and the structure of the Milky Way, topics which he writes about in his long running "Universe" column in Natural History magazine. Tyson's varied honors include the NASA Distinguished Public Service Medal and People Magazine's 2000 "Sexiest Astrophysicist Alive"- City Arts & Lectures
Neil deGrasse Tyson
For the past decades, Dr. Neil deGrasse Tyson has been at the forefront of teaching science to the masses. His singular achievement has been to make the impossible, accessible – and the complex, understandable for millions. In the course of doing this, he’s learned a thing or two about how to teach the hard stuff: how smart fun changes everything and can drive unprecedented engagement.
Ryan Wyatt assumed his role as Director of Morrison Planetarium and Science Visualization at the California Academy of Sciences (San Francisco) in April 2007. Prior to arriving in San Francisco, Wyatt worked for six years as Science Visualizer at the American Museum of Natural History in New York City; previously, he opened technologically-advanced planetariums in Phoenix, Arizona, and Albuquerque, New Mexico.
Wyatt’s professional interests include making research data sets accessible to the general public, and developing standards and “best practices” in the fulldome video community. A paper co-written for Natural History magazine reflects on the role of modern planetariums in bringing cutting edge science to a variety of audiences, and his “Visualizing Science” provides an informal look at his ideas and opinions related to visual representations of science. Wyatt also indulges avid enthusiasms for archeoastronomy, the history of science, and intersections between art and science.
Astrophysicist Neil deGrasse Tyson argues Earth is not as an ideal environment for the existence of life as most people commonly think. "99 percent of all species that ever lived are now extinct," says Tyson. "That is not the signature of a planet that is in love with life."
Cosmic body with gravity (seegravitation) so intense that nothing, not even light, can escape. It is suspected to form in the death and collapse of a star that has retained at least three times the Sun's mass. Stars with less mass evolve into white dwarf stars or neutron stars. Details of a black hole's structure are calculated from Albert Einstein's general theory of relativity: a singularity of zero volume and infinite density pulls in all matter and energy that comes within an event horizon, defined by the Schwarzschild radius, around it. Black holes cannot be observed directly because they are small and emit no light. However, their enormous gravitational fields affect nearby matter, which is drawn in and emits X rays as it collides at high speed outside the event horizon. Some black holes may have nonstellar origins. Astronomers speculate that supermassive black holes at the centres of quasars and many galaxies are the source of energetic activity that is observed. Stephen W. Hawking theorized the creation of numerous tiny black holes, possibly no more massive than an asteroid, during the big bang. These primordial mini black holes lose mass over time and disappear as a result of Hawking radiation. Although black holes remain theoretical, the case for their existence is supported by many observations of phenomena that match their predicted effects.
Sorry Neil, love you, but it's getting worse!
Average Global Temps SPIKED +0.6C (+1.08 degrees F) since 1975.
Summer Arctic Sea Ice dropped -50% since 1980.
Since 1950 atmospheric CO2 has spiked +30% over highest levels in 400,000+ years.
CO2 Ocean Acidification is up +30% since 1900!
For more data & documented info. on Carbon Dioxide/CO2 Concentration, Global Surface Tempera-ture, Arctic Sea Ice and Land Ice (Antarctica & Greenland) & Sea Levels
BTW, just ONE American child consumes the energy & resources of TWENTY poor Third World children.
Our Spaceship Earth's life support has been crashing since WWII.
Oceans are poisoned and over fished by much as 90%. Rain forest has dropped -25%.
CO2 ocean acidity has gone up +30%. Ocean acidification will kill CaCO3 forming coral, plankton, and shellfish by 2030.
And Int'l Predatory Corporations now OWN America - all they care about is deregulation, dodging tax-es, short term profits and BIG BONUSES!
"The late, great, spaceship Earth!"
I'm a geologist and generally don't like listening to people when they talk about astrophysics, I enjoy the subject its just usually too boring to listen to, but with him I can pay attention, and learn a lot.
I've heard this theory that tidal forces would rip you apart if you fell towards a black hole. It doesn't seem right to me though. I don't think you would actually be squeezed by space contracting all around you. I imagine you would contract with it. It's not that the full size you, has to suddenly fit in a smaller place. You are also part of space. Your atoms would not get closer together, relatively. They would get smaller and their relative distances apart would stay the same. So you and your spaceship and the air in it might get really small. But would you even notice?
In less than the blink of an eye, you might just pop back out into a fully formed and sized reality and never even know what happened. Perhaps it happens all the time and we don't even know it.
This kind of discourse helps novices such as I by answering a multitude of questions in 30+ minutes, without annoying commercials and overbearing musical backgrounds interrupting aging trains of thought. Thank you Mr Tyson and Fora TV!
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 onairplanes let's see if I know you astrophysics the outcome the questions that have questions orcatastrophe question when life hands will the asteroid come up with well the universe and what willearth spin off its axis will the Aztec calendar destroy the earth is all there theboat on the necessity of people like death and mayhem so I'm article titled the bookwith that because of the whole chapter on how to die as you fall into blackhole which I personally think it's kind of cool whip it up if you gotta gogotta go to so that's a new chapter called Mrs Betts one essay among one chapteramong seven chapters under the title on the sub heading when the universe turns bad alwaysthe cosmos wants to kill us so just one of those ways you could die andfor me that's what we think we like well yes it's that some like what thatyou would die that way what happens is the gravity of the black hole use theextreme as you can imagine light doesn't even escape its gravity is so extreme like travelingat the speed of light bright light just to put that in context if you wantto escape the earth it's actually possible to do that country which grandparents all with asuitable goes up must come down this is not true well there's nothing your grandparents everthrough that never came down but with rockets with high speed you can sense some thingsthat never comes back for earth that's speed is seven miles per second we're going to escapevelocity but if I throw something that Apple to it what love is not fast enoughto come back so most of life experience tells you what goes up into seven miles persecond is never comes back to go to the edge of the universe there ok sonow turned on them on a black hole the escape velocity so high that you havespeed of light isn't good enough so if light to think about the films coming out its blackto fall when you're not coming out that a one way trip it so if youdie this way you won't get to tell anyone how you died I it's a start butsecond as to fall in don't just die Creek you disappear you die long before todisappear as to fall in the gravity at your feet becomes rapidly greater than the gravity at your headnow now it turns out as it's you stand on earth the fact is true under those conditionsas well because your feet are closer to Earth center in the proper credit to goofy actuallyfeel a stronger force of gravity but not by much because it feared oh five ft tallsix feet tall and earth is like four thousand miles in radius that difference is notthat great compared with the distance to the center of the earth black hole they're so smallso compact that your height becomes it matters as you all when towards debacle so goofystart flowing faster than your bit to us that's a bad situation of the year don'treally additionally each other feel good you know it's heavy you real stretch when you wakeup morning initially it feels like a stretch for general relativity can you ok to havea job to cosmic joke but what happens is that stretched continues beyond comfort level andyou reach a point we are going to call the tidal forces tights under body basicthat of fortune so great that they exceed the inter molecular forces that bind your fleshand so the point comes when you smack into to pee likely to happen at thebase of her store now your two pieces know it turned out I don't even askabout this but I have I got a whole chapter on the Titanic so it turnsout you will survive that smell because below your waist while there are in court infour games there are no vital organs below your waist so it was so will stayalive for a little while ok it to bleed to death with this all happens muchfaster than would take to bleed to death so these two pieces then feel tidal forcesthey snapped into two pieces it in a snap again continue it in sixteen ten acrefight for treating your weight that so eventually it your head and multiple other parts andso that will continue until you are a stream of atoms descending toward the effects itturns out that's not the worst of it it turned out the fabric of space andtaught almost down towards a black hole so the space to chew occupied up here heis larger than a space to occupy down here so in fact you're getting while you'regetting stretched you're getting squeezed excluded from the fabric of space like toothpaste to it toonow we have a word for that call speak edification the bed stop invented for justthis purpose one thing more good editing which is having worked for ways to die rightwith a word if you kill someone else the word few different word if you killyourself differ were to be killed by electricity that if it were to be all workfor how the dock its unification too they go with in in addition to more exoticwhat digress to the question to answer sorry in addition to the more exotic ways tobut you've also talked about more mundane was in fact more likely with is that truththat the impact of the most liberals spot up by cosmic catastrophe in the chapter asa whole other chapter called coming attractions asteroids this is a real issue this is somethingthat one is headed for the Pacific but this time at the end of trading wewould love a holiday and in prayer cool stuff to talk with this book right nowto another we can do about it so I tell you we can do right sothe typical office headed for the Pacific Ocean five hundred miles due west of Santa Monicawhich is of course south of here but um with QQ location and college for dimensionwe'll talk with you know cleaners MRI and a socialite talk about it now it thisalmost all the way is that far there is an asteroid discovered in December two thousandand four call puffs named for the Egyptian God of death and darkness it was namedall week after the trajectory was identified to intersect that of her at the top inthe case we would not have named to the office you name it might just endhere so pretty some non threatening this one was headed towards Earth of puffs alright onceyou discover an asteroid you gotta wait a little while to get enough of a segmentof its work to calculate what the full board will be to know if it willcome in harm's way so we did that we the community I was when we gotto this day so peeps if you're over thirty means people forgive say God keeps hispeople it's actually a whopping for this bright smile a little more than nothing right sowe get the board turned out be the year twenty twenty nine the month of Aprilthe thirteenth of May Friday effects profits will come so close to her that will dipbelow are working to make patients at once and it is the size of the RoseBowl to be the largest closest thing we've ever observed to come by her now ofcourse a much bigger asteroid check out the Tigers we work around the top so thisisn't in the era of observing the cousins with technology this to be the closest biggestthing will ever see come by now the work that we now have poured it ona certain enough because these things are hard to measure hard to get an exact distanceor to sponsor it so we cannot tell you exactly where that trajectory will be weknow what hit her we know be closer than the orbiting cent there is being rateto six hundred miles so because people the asteroid goes the middle of the key allit will hit the or thirteen years later it will hit the year fiber tomorrow sofar km due west of Santa Monica it does matter where it goes that you knowthat most of the center if it goes through other places within the keyhole been nocontact point shares further into the Pacific or closer towards plots North America yes it butbecause of the center it hits the Pacific Ocean just that it to the Pacific toa depth of three months at which point it explodes hitting the Pacific don't hold itsthree mile walk three miles that will send a tsunami wave outward from that location that'sfifty feet up by store options don't like having holes stop this forty my own heartaward all goes well you say this with commitments it collapses we were all high wallof water thank you fall back into the hole squashing against itself with such ferocity thatIran is it high into the atmosphere and fall back down to the ocean kept eatingthe ocean again you make every second time this cycle takes about fifty seconds you cancalculate ok so here comes the first bombing the fifty seconds later comes the motion onso there you are on the beaches of Malibu tsunami comes in now auto like thetsunami hit Indonesia which was one way the twenty fifth to the shore this first onehe knew he was the supply of water to exist so that the next wave actuallysocks back on it to create self soul this on the new legal in about aquarter mile the we have the sound effects person the road so I was in aquarter mile before get sucked back out for the next wave to come here's the problemwhatever was there on the coastline is now brought back out to sea in the nexttsunami brings it back to the shore all the million dollar homes in Malibu they gettaken out to the sea bed and back but this time they are slightly different shapeit so what happens is all call them ball be artificial stuff all the houses thefactories they get churned into this up only two blocks Dex and laughed the entire westcoast of North America so happy with that so about this big school so I setup thirteen years after twenty one that I miss pump up its April thirteen twenty twentynine and it's a threat to kill it it will get hurt people thirteen twenty thirtysix so tickets to a second the foreign press I don't have what I know youare right now that I didn't know my heart open with it though so bad butthis begs the question was whether that way will be felt up in the Pacific rimbut Japan cross wide can expect to fix farther from the impact zone so the waveof the low low but the wall feel to continue for about forty five minutes whatwe do what we do about it well marker tell her ok I have to peethe film did we start but you just did of joy primetime running away from thatfinancial disaster it why is it that this is a flood we gotta run from thefourth the heartache that the Seaway the volcano I think in terms of the twenty firstcentury people why we like stop it from happening in the first place what to readabout what one with why we building tornado shelters rather than to have stopped the tornadook we should think differently about the problems we face but it's parked in the chairfor the chapters of ways for a plus to kill us right this in response tothe people out there who say all earth is just perfect for my oh what ahaven of all the universe just right I just lie every opportunity to try to killus the salon to the public in a tornado after what does that according to thetown of Red Robin but making sure did ten minutes later and consulting each year okI got a problem anti God earth is bad for life so that he is thefossil record eighty nine percent of all species only and are now extinct that is notthe signature of a planet that is in love with life what the we stopped tolook at that making this up fortunate to get me started so yes what we dobut Castro there people who look to see which one to hit them or someplace elsefrom St while it might become an engineer and forgot how to deflect it ok actuallythe two camps of it there's that supper on Scott his old foe we've met thatwe know what they are we got the new slid open the silo take a napnot tear it down we are we that if we Americans are very good at blowingstuff up with this good at understanding with the pieces go after close to the daythey cute that's just how that works so if you wanna call the store any USAyou hit it with a new candidate splits into two I have to be back withtwo plates on it instead of just war you know like if you only have togo to smithereens Sophie will burn up in the atmosphere but you have no guarantee ofthat don't guarantee what stuff looks like after blows up so we took our little ponyup a bit of difference of nemesis also but not so subtle office we can surviveto be really beautiful of meteor shower do with it with the soppy and that theywould be a warm night well in the saddle like the parts short pants it wasa dislike to be toasting there will be toast slots you know this California you'll beasteroid impacts to like it might do for us right to become a turnaround has beensomewhat biblical disaster going on out here the Flyers have it probably will when the locustscommon in the fraud it off it the scope some really dope she likely wouldn't wakeof the locusts I've really come out of it or not on plus has overseen acomedian joke about take credit for this job the comedian noted that all these disasters acarport all like happened in the rich neighborhoods right for neighbors never liked affected by thesedisaster so some cosmic were forced on network TV reported on the theme of the umbut so do we get back to work so all the e better be for mymoney the more sensible thing to do is to deflect the top people working on tofortune scenarios right now the one that is if this is the opposite it's possibly determinedto win the test tube really need to score well only the battery for second cupof the Cup with Becca Jessica go along profits come into effect so that reflection scenariois to give station to be look somewhat that right you come up to it andthen use com or parking next to the statue that we know we use in partto sing some more orbit the yep our kids with um is very little easier towhat was happening the parallel park it as another so so what happens if both theasteroid and the station the ways couple tons of forty me each have mutual gravitational attractionso they will want to deport each other the problem rapture rockets that prevent that fromhappening what's it going nutso to prevent it everytime you prevent it actually tolling the actualfrom its intended path that is a gravitational gravitational tractor if you get it early enoughyou know how to live by much we have to do is have it meets thekeyhole that's all you don't want to go to the feel of it if you missit one direction it to overshoot her to go to the direction you wonder if youare what if Jackson would drag it into the keyhole I would be bad don't wantthat to happen actually dragged into the keyhole if you would be on popular so hotthat we the people working on that this the right time scale people are today willbe a live band and we just need a reason to label thirty but to topit off the west of stress right now the super the gospel or so up sothat's the best that tonight you know you've actually just described a scenario that appears andthe current Americanism actual history state show cosmic collisions and that just because I have asort of vested interest in a trance but just distract you from of black holes Mastersfor second you were involved in a really principal motivators and transforming it into a turnwhich is one of the vehicle for a regional conference in the country too but twentyper cent to touch I am but before anyone else has done that so disappointed onecommon process capture a planetarium you know there are many scientific disciplines that can boast ofa facility that introduces the uninitiated public to the frontier can feel that you know whatoff select him as well use for us that's what quite like Netflix to museums areto have the fossil dinosaurs there by the way our talk like paleontology colleagues they don'tlike this at this our effort to counter the test with that never forgiven us forthat um nevermind and that was the asteroid we would still be running under foot TRex Cafe we were what servers Carmelo ancestors what stirs for T Rex two asteroids wethink of them is that but the pry open new ecological niche to allow greater theexperimentation of our favorites before turns against them find another way to kill to try tostop the planetarium its attendance was dropping while the tenets of the rest in his earwas rising sweet to stop and chat and it was getting cold and sleepy and dustyand was still disappointing up consolation when that's not the frontier of astrophysics and so weinvest in future government although less money than what you guys for spending to be completelyrebuilt how Academy erm our costs twenty three million dollars half of what you guys arespending and sold it build a building where we can leave me the bright green buildingor death very green the public's old Hamilton stuff but quarter in cycling through I'll checkit out like it but we didn't get to the reef to decide if it wasraining so to get soft ever needed so we rebuilt the facility and no instead ofshowing slides of pretty pictures of the universe we load up a supercomputer with a threedimensional data that we know that up with a soul system but still it is traditionin our galaxy gas clouds the distribution of galaxies in the universe below the top thenget projectors on the dough that seamlessly marriage to have one continuous footprint and though youproject a charity the room with a three dimensional data set on the go some oldare you just work on earth asking what time of night is where my on theplanet you're saying what platinum while and what Galaxy right now forty two pence and sonow the entire universe this post and the attendant grew by a factor fun with itmiddle of one leaders can truly bring twenty first century a strong need to apply turnfrom two weeks for the kids yet I consider somewhat for tapas bars by its veryfirst day was very geo center and that's fine it's ok to a point but hereally was attractive moving frontier bash for physics you gotta change although I feel the worldjust by standing still so that's what we did get me to just listen to meat just this process of a car show his cosmic collisions every naturally we create foryou the collision that took up the dinosaurs sixty five million years ago the new seatof what Brian was referring to concerned about suppose to do people the rate of profitsinto multiple little parts the energy is still there the energy of collision is still thereit just doesn't make it to Earth's surface genetically with that punch into the ocean heturns up with the FSB heating the atmosphere so the concern is governed top of thathappening this flashy can ignite sorts of things that separate topic enough for that by theway to know the spy satellite that shit you saw that in them my phone wasringing off the hook I said I'd get somewhere on time ok at all despite thisthe satellite before that this guy ok this happens all the top you dislike curious aboutit was a spy satellite somewhat fall out of stock they did not have this peopletoday are so the war the worry is that my kids about this is borne outof control so with the Detroit do is be with you know Tomahawk the weapon upthere to break into more pieces so that no large piece survived a trip down tothe surface and have some form or discover all our treasure seekers in the spy satelliteso that's what they wanted to break his will so that they were with him andthe parting of pieces but what happened at what they call the K T boundary thatrenders the dinosaurs expect not only does that have stored with the size of Mount Everestplunge into the Yucatan Peninsula of course it was called that but that location of theair but the crater with fifty miles across cast millions of tons of Earth's crust intothe stratosphere that was passed for debrief brains back down burning up flash fire in thefar it's in the dating of the vegetation creating stop rising high into the stratosphere walkingthe earth preventing photosynthesis knocking out the base of the food chain in sending a wayof extinction across the tree of life seventy percent all species honor when extinct because ofthat a new sound of that they like or are those can I get the carlet it go so we recreate that for the show what's funny about it its resultsit will do so okay for my children then the funny thing is it really creepsout the adults kids love get on the video game cannot make it that every daythe package the parents that can scare so we show that was another Collegians as wellwhat was permissible shot with the times for scribbling you for children of the traditional waywell actually the goddess or whatnot look at the oversold because the asteroid would be collidingin twenty miles per second which is way faster than the speed of sound the windowcause I often look to watch that happen because it's way faster than the sound ismaking so if you were anywhere to have it you will have no idea it WallyWood season explosion of fun it would be vaporized first to come then you go rightbut no details yet but a QB you be a prize at the ground zero ofthe impact that's the fastest way to go it around the side he would then beincinerated from the four fires if you were somewhere
