The Day the Mesozoic Died: The Asteroid That Killed the Dinosaurs - HHMI BioInteractive Video

Ever wonder why the dinosaurs disappeared? HHMI BioInteractive investigates the cause of the mass extinction at the end of the Cretaceous period-and the clues come from paleontology, chemistry, physics, and biology.
This three-act film tells the story of the extraordinary detective work that solved one of the greatest scientific mysteries of all time. Explore the fossil evidence of these prehistoric animals, and other organisms that went extinct, through this lively educational video.

[@tsopmocful1958]

@@johnolpenda9803 Please keep in mind that most scientists like these palaeontologists are very passionate about their work, are very interested in the subject, are very curious and are probably the type of people that get a lot of joy simply from solving and completing difficult puzzles of any kind, so their motivations are not completely selfless. Of course their primary aim is to contribute to human knowledge, but they wouldn't be able to to study and work hard at it for years without enjoying it in the first place. People produce the best results if they love the work they do, so gaining a career that matches your natural interests is an excellent achievement in itself. So if you wish to contribute to the world, the best place to start might be to work out what you are most interested in or what activities gives you the most joy and capitalise on it somehow. And if your main love is simply in helping others and you aren't scientifically inclined, there are certainly many options for that, ranging from healthcare to teaching or from charity work to conservation projects. But the main thing to aim for is to love what you are doing, because every day you do it will be a pleasure, which means that putting in lots of hard work and time will never be a problem for you.

We’re basically living in a post apocalyptic world

[@classickruzer1]

When Adam and Eve lived in a paradise Earth and then rebelled against God, this is how God cursed the earth as he had told them he would.. the asteroid hit so hard that it shifted the earth's axis by 23 degrees. If these scientists could figure what angle it came in from, based on the degree of impact, they would know the exact position of the earth when it hit.. That would be interesting and would also confirm the fact that it did cause the earth to shift on it's axis.. It would have had to come in from the South Pole and struck North of the equator..or it would have had to come from the North and struck South of the equator. When the earth shifted, it resulted in the tectonic plates breaking up and pressure from the earth's core releasing massive amounts of pressure that pushed the sea beds up, creating the tsunamis, volcanoes and mountains. At zero degrees tilt, the earth would be a paradise, with it's foundation all intact and very mild seasons, along with perfect tropical like weather... plush foliage throughout the entire earth. Palm trees and other tropical vegetation have been discovered under the ice at the North Pole.. Mastodons found frozen with vegetation still in their mouths under the ice at the North Pole..Proof of a once perfect earth that flourished over the entire planet.. And B T W , there were never any flesh eating dinosaurs.. Scientists base their flesh eating theories on the size and structure of their teeth.. They've found no evidence that dictates any kind of dinosaur dieted on flesh. Those dinosaur that survived the asteroid could have possibly fought others over the scarce vegetation that survived, thus presuming they were flesh eaters... but prior to that, they and all other animals survived on vegetation. Scientists are always looking for something new, which is great, but some do it in order to get recognition for themselves and then convince others to adopt their suggested findings. Just like carbon dating.. determining the amount of carbon 14 in the remains of deceased animals and the rate of decay... It isn't overwhelmingly accepted by all scientists as fool proof.....therefore, their dating of events consistent with fossils and bones of the same era aren't fully accepted as accurate..

@@mp3ste1 read about the great flood, in Genesis. Then you can research how the dinosaur fossils were all found in great heaps together, in the layers left by the waters, with their necks thrown back.

Very interesting I learned more here about what happened to the dinosaurs then I did when I was in school.

Fun Fact: If some alien race 65 million light-years away were to take a picture of the Earth they would see the dinosaurs on Earth.

[@meghanachauhan9380]

@Tcbranger dang it

[@wrongturnVfor]

Well, if you could build a craft that could fly faster than light, then you could go to a planet X+65 million light years away X being the time for the craft to get there, you could take a pic yourself.

[@rosairedubrule60]

Lets hope they do not have reptile phobia and launch their mega laser

[@astr0nox]

It's an insanely difficult task. Our picture of M87*, the black hole, which is 53.5 million light-years away, took a telescope basically the size of the earth, yet we only see a fuzzy outline of the black hole even though that shadow is about 312 AU across. Earth is 0.0000000852 AU in diameter, which makes imaging it many orders of magnitude more difficult from that distance, let alone individual dinosaurs on its surface.

One of the best American documentaries I've watched! Educationally informative yet concise without the typical over hyped and over dramatised narrative and effects. Well worth viewing.

[@1bkres]

Then you need to watch Kent Hovind on dinosaurs. He uses actual scientific proof instead. life changing.

[@angelarussell3491]

How right you are. The number of American documentaries with amazing potential , that I have stopped watching half way through because I can no longer put up with : 1. The overly dramatized voice and 2. The intrusive 'musac.'

Thanks for such a lucid explanation with good graphics. I just wanted more specific dates of discovery. I think the NY Times showed the blurry date January 29, 1988. But I'm not sure. I'm surprised at how recent these discoveries are. No wonder my old Life books have it wrong. Again, great job! Thanks.

[@luisabarca7363]

Phaedra... I was also, like you, interested in find out the blurry date of that “Science Times”'/ “The New York Times”... For your information, the correct date is Tuesday, January 19, 1988... Yes, I agree with you: a very recent discovery, indeed!... Keep alive your curiosity, Phaedra... Cheers!

This is one of the best explanations of the mass extinction of the dinosaurs that I've ever seen. I loved the history portion of the video. My dad showed me the KT boundary when I was a kid and I thought it was pretty cool. It really must have sucked to be alive on that fateful day. REMEMBER - Another asteroid is on its way. It's not a matter of IF, it's a matter of WHEN.
