- Rich Muller, a Berkeley Lab physicist, discusses Nobel laureate Luis Alvarez and colleagues' 1979 discovery that an asteroid impact killed the dinosaurs. He also discusses what scientists have learned in the subsequent 27 years. Alvarez's team detected unusual amounts of iridium in sedimentary layers. They attributed the excess iridium to an impact from a large asteroid. Series: "Lawrence Berkeley National Laboratory Summer Lecture Series" [10/2006] [Science] [Show ID: 11829]
So often attempts at humor are cringy on such presentations but this guy is naturally genuinely entertaining.
Tho I was familiar with most of this material the details of uncovering this fantastic story are highly compelling.
Thanks for uploading this program. I had saved it on my DVR back in 08 and used to watch it all the time. It got erased and I have been waiting for it to re-aired on TV.
Now I don't have to wait any longer. Thanks
A wonderful presentation, putting enormous emphasis on catastrophic scene caused lively. This is as usual when it comes to mass extinction is dealt with. Then, wonder, or miracle, which is haunting me is how reduced numbers of survivors weathered such a harsh condition & regained their lives to evolve again?!
What a brilliant presentation. So clear and lucid, even for a layman.
Muller was right about one thing - The Nemesis theory is no longer (2021) considered viable after detailed InfraRed faint object telescopic surveys.
i have learned so much, thank you
Thoroughly enjoyable.
Some people really excel at public speaking. This guy's one of them.
And typically "academics" fail miserably at humor but he's naturally entertaining.
WOW THIS WAS IN 2008 AND I AM WATCHING THUS WOWWWWW .-.
...when he makes his comeback will he go on tour again?
I praying for it...
..in just a few days.." .. chills!
Got to agree with your 'learned' reasoning there dorrtay,itseven younger i reckon.Just the other day i dug up a T rex [who winked at me] and along side imbedded in the same rock was a Tesco's shopping trolley........
Very good speaker. Nice stuff and very clever. Feel sorry for the IT guy, although happy I am not him.
Watch and learn from many sources and develop your own conclusions....
Huge electrical events with supersonic red hot winds and vortex would have done severe damage to anyone who was around at the time. The comets would have supplied the energy required and if you look at Mars then you can see the catastrophic events electricity can cause instantly.
you can be autoditact like i am and not only in science but with astronomie the rooth of words theology too it is so fun, even the history and archeology ,well i love to study all kind of thing and let me tell you it change your view on the world
He never got to the questions! lol
Ok
Nemesis = Nibiru = 2012 ?!?!
we believed in Religion longer than we believed in Dinosaurs, due to that we only recently found out about Dinosaurs (prospectively speaking), but now we debunk Christianity and follow science. Mainly due to boredom of the first story. I wonder what happens when we bore of the dinosaur theories... ...
ajwasp the difference is we have EVIDENCE of dinosaurs, dumbass. Where is the proof of the exodus?
what dinosaur theories, the truth is in the rocks, seek and you will find the truth
I Think The Dinosaurs Died.
@drav1dan
there is no good - only one - me!
I realy dont find whats so funny geek fuckin world
This absolutely untrue about earth and living things. The earth is just 6,000 years old going by God's creation
you have to have physical evidence to prove it is only 6000 years old, anything else is pure fancy and delusional to ones self
have you seen the crystal caves in mexico? it takes 10's of thousands of years for crystals to get that big.... time to open your eyes and walk away from the indoctrination you've been taught to believe by others. try reading older scripture than the corrupted bible, like the Gospel of Thomas, or the Sophia of Christ, these and many more are in the Nag Hammadi texts, on line.... and were probably the original versions of modern scripture..... and Christ himself teaches the truth about the universe, and our world. :) check it out... with an open mind.
So you got absolutely NOTHING out of this, SAD.
@@Mrbfgray, you are replying to a comment I made 12 years ago. I was much younger and still learning a lot then. My views have long changed. Thanks! 🙂
@@dorrtay HEY! That's really cool. We should all strive to be that flexible, as we learn we change our minds. (can't believe I just subbed FOX NEWS due to Tucker Carlson's take on Canadian Truckers, lol)
