Astrophysicist explains why dinosaurs died when crocodiles survived

Astrophysicist Hakeem Oluseyi breaks down a new study that suggests how the dust from the asteroid that hit Earth blocked the sun to an extent that plants were unable to photosynthesize, a biological process critical for life, for almost two years afterward. #CNN #News

[@sharathsh9987]

I met Prof. Hakeem when he came to give a lecture at our university a few years ago. He's exactly like this. Very passionate and very smart.

[@sutters7251]

So smart he doesn’t realise that cold blooded animals need the sun for their energy. You lose the sun because of the dust then those cold blooded animals would perish just as warm blooded animals would perish. No there’s a massive hole in this theory.

So where did all the warm blooded animals come from if all that remained was cold blooded creatures

[@omaha2pt]

You will find it's the other way around. Most cold-blooded animals (dinosaurs) died out. Crocodilians survived because they needed far less food than their huge-sized cousins the dinosaurs. As for warm-blooded mammals, they already existed, they were small and thus needed very little food, and sheltered underground, only coming out for food, like mice do today. Small avians survived due to needing less food as well. To be clear, the global winter that the asteroid caused affected all animals, all populations were decimated, but the ground-dwelling dinosaurs (as opposed to birds) were wiped out completely, never to return.

Sure, immigrant systems are woefully slow. Many years to slow. Biden has been changing legislation to improve/ change the current systems. Unfortunately, it's not enough, fast enough, but at least he is doing something unlike previous presidents. Statistic demonstrate that the majority of people crossing the southern border are asylum seekers, who become legal immigrants once they have their paperwork processed. It's a long process of years of red tape. Statistics also show that the vast majority of illegal immigrants arrive in the U.S.A .by plane, with legal paperwork, but out stay their visas. Many registered illegal immigrants, with their legal status lapsed or pending, including asylum seekers, don't risk returning to authorities or court to update their legal immigrant status, for fear of being erroneously deported. Especially during Trump's presidency. That is how the number of illegal immigrants rises. The processing systems are broken. Fun fact: the U.S.A. is already a national of immigrants. Even the Native Americans originally migrated to Northern America.

Just quoting a snippet from his page on Wiki: “Oluseyi earned his Ph.D. degree in physics from Stanford in 1999[1][6] under the mentorship of Arthur B. C. Walker Jr., from whom he learned experimental space research. Under Walker's tutelage, Oluseyi helped to design, build, calibrate, and launch the Multi-Spectral Solar Telescope Array (MSSTA), which pioneered normal incidence extreme ultraviolet and soft x-ray imaging of the Sun's transition region and corona.” Now, by my standards, he is a real scientist.

@@mikemccormick6128 He said the big dinos went extinct because they were big and warm blooded, which means they needed a lot of food. AND he said gators didn't go extinct because they were a lot smaller and cold blooded, so needed less food. But insects are absolutely miniscule, and cold blooded, so need almost no food. Just over 82% of all insects are estimated to have gone extinct during the Great dying. If size, cold-blooded-ness, and amount of food is what was important, then insects shouldn't have lost any species really. There was a one ton land animal, that survived the extinction and did VERY well. While a land animal similar to alligators,(also aquatic) around 3 tons survived. So according this astrophysicists explanation, why did most of the tiny cold-blooded insects go extinct?? He oversimplified things, to the point where he was wrong, and the fact is there's a lot of luck involved in surviving something like a mass extinction. Remember, not going extinct doesn't mean that species did good. It just means not all of them died.

@@lordgarion514 I'm not saying that you are wrong and I'm not an expert. I tried to verify your 82% number and couldn't find anything. I look at it a little differently than you in the sense that insects did not go extinct. I think you would have a better argument if they had gone extinct. Also, many insects rely on plants for food, so many of these species would have gone extinct from lack of food. I couldn't find anything on the 1 ton land animal.

​​@@nkanyisomdlalose3702 But black people are just as intelligent as any other people, so why you would be particularly proud? 🤔 Wouldn't you just assume that many black people are going get educated, as with other people? It seems like you are proud because your expectations of black people getting educated are low. That's why your comment seems racist to me. Your pride seems to imply that you think black people have additional obstacles to overcome, which makes their achievement special, not the norm. Maybe you do mean that, in terms of opportunity, not in terms of ability to academically achieve. So...do black Americans have limited opportunities to attend university, and complete a degree, compared to white Americans? Is that it? Sorry to trouble you with this, but I really want to understand.

[@arielheinsberg5827]

@AlGilani-nt3zq you can’t even accept a black man achievement without mentioning BLM , your hatred toward black people is mind blowing.

*_FUN FACT:_* _In the ice age when the ice sheets started to break up do to global warming. The Polar bear populations started to grow from that._

[@daniellamcgee4251]

That is a fun fact! 🤓 It's as if polar bears need not too much ice, and not too little ice, but just the right amount of ice. Did you get the 'Goldilocks and the Three Bears' reference? 😁

Wow, you anti-science corporatists have an ASTROPHYSICIST to explain this completely not-astrophysics question. You might as well have a kindergarten teachers on there. They'd probably be less obnoxiously condescending, as well as being just as competent as, or more than, this guy on the subject. Or in general.

Incredible!! Very interesting and informative. Being from Florida, I always seen Alligators as dinosaurs which they obviously are. Makes total sense as to why the survived the end of the dinosaurs

[@bobjohnson7020]

Alligators and crocodiles aren't dinosaurs. Dinosaurs weren't reptiles. They were birds. The last common ancestor of both crocodilians and dinosaurs was about 250 million years ago, whereas dinosaurs didn't start dominating on land until about 200 million years ago. By 65 million years ago, crocodilians and dinosaurs had diverged significantly in evolution. Most crocodilians also became extinct along with the dinosaurs, but some smaller species survived, and are actually not much different today than they were then.

Alligators are not dinosaurs. Birds are dinosaurs, more specifically, a type of theropod. Both alligators and dinosaurs are archosaurs

[@Spiritof_76]

NOT obviously. Crocs are not dinosaurs just like snakes are not.

[@jordandthornburg]

@@bobjohnson7020dinosaurs were birds. So a T rex is NOT a dinosaur just to be clear?

anything and everything that could not crawl underground or swim deep into someplace was washed away.... that's why mice did so well... our common ancestor...

[@AnthonyLee-dj1xo]

Yeah, they can survive just about anything, even if it's freezing cold oddly enough they can survive, which shocks me since they are cold blooded.

I wish I could of seen how the dinosaurs reacted. Must be strange having your world go black unexplainably.

[@c0mputer]

They were probably like, “Oh no!”

[@senantiasa]

Just put your cat/dog in the bathroom and turn off the light. The dinosaurs probably reacted like that.

My kids learn a lot from him on “Baking Impossible.” He explains the mechanics in a way that she understands it. 🎉

[@ElRayDelRio]

Hahaha this is hilarious. Dinosaur is an invention by man to describe what were dragons once upon a time. Yes, the dragons luka (last unknown ancestors) is the bird. That I agree as the birds bones are extremely porous and petrify much faster. The bodies disengrate in a short matter of time so this will explain why the scientists believed dinos to be closely related to birds but in fact are DRAGONS. Oh, and a unicorn is merely a Rhinoceros 😂.
