Searching for Alien Earths
October 24, 2024, at the Linda Hall Library
Astrophysicist Lisa Kaltenegger, founding director of Cornell University's Carl Sagan Institute, demonstrates how we can use our home world as a Rosetta Stone, creatively analyzing Earth's history and its astonishing biosphere to inform our search for life in the cosmos. She takes us on an eye-opening journey to the most unusual exoplanets that have shaken our worldview-planets covered in oceans of lava, lonely wanderers lost in space, and others with more than one sun in their sky-and the best contenders for alien Earths.

How to Clone a Mammoth: The Science of De Extinction
This is a must be listened to talk and its equally as wonderful q&a. Thank you to Dr Lisa Kaltenegger for sharing your knowledge, passions, and time with us. And, thank you to the people at Linda Hall Library for sharing this talk. 🪐🌸
Thank you ALL🎶🌸
The speaker gets into a bit of a knot when he speaks about the "hybrids". The existence of fertile "hybrids" rather shows that Neandertals and "humans" were the same species, but just rather different populations.
Contrary to the phrase "empty space", space is not empty. How do you know that the light that you receive from many light years away has not been influenced by molecules between here and there? When the example of one is 80% parasitic I would not be particularly optimistic concerning life elsewhere being Care Bear friendly. Surely we would not prove to be just so based on our history... no, it is not a thing we have overcome. Science has no room for hubris and romanticism.
Too interesting. Thank you.
Lemurs are actually our closest relatives... update required.
We have come quite far in the 14 years since then. We even finally got JWST up 🙂
Thank so much
Tip. Put on 1.5 speed
their may be a flaw to this, whatever ejecta matter that broke free and landed on the surface would of been covered by kilometers of dust/dirt/rock now. So youre recovering the latest event debri
That is one sexy scientist. Yeah, I know. Sorry.
Is her chin glued on?
terrible.
Did I catch that right she said the solar system earth belongs is 28 light years from the center of the Milky Way. I think she meant 28 K light years to the center
Brilliant presentation. Clap clap
Wonderful lecture!
l am a Dawkins fan, but those tweets are ignorant.
Excellent Info
Lisa Kaltenegger ❤
Excellent talk! Wish I could have joined for this lecture! Hoping to see the exhibit soon.
What is THE POINT OF RESURRECTING MAMMOTH??? SERIOUSLY.
We wuz neanderthals
Charles Darwin was in fact heavily influenced by David Hume. Theorizing on how to do science is really hard without a map, you don't just pick a stone, compare and without having any radiometer won't immediately give you answer (especially when casual chain of reasoning can be very wacky)- these are some major philosophers has already been mastered since they do it for almost 2100 years now...
He is incorrect . They are controlling us !
Enjoyable and interesting presentation with humour in the end.
130,000 years for earliest homosapien fossil record? I thought it went back at least 300,000?
I really, really appreciated watching this. Thank you!
Romans 1:19-22
I wish the audio was not so problematic. Love E. Kolbert.
What makes us unique is that humans are sentient spirits and everything else is an extension of that.
yeah, no afterlife if evolution and you can't handle it
@@AMC2283 ???? Are you a crazy scientist? I don't get your statement.
This is all from an official b.s. standpoint that many scientists don't even believe themselves but have to propagate to keep their status, salary and pension. The b.s. part is that a human being is 100% matter, chemicals. It is very easy to demonstrate that there is a LOT more to it. It all stems from the 19th century philosphy of materialism. Materialism is the dominant philosophy today and the biggest lie ever, dwarfing even the avalanche of lies Trump spouts on a daily basis. You are not a blob of mud but a spiritual being housing in or near a body. Ask this guy how a body can grow from DNA. How does a cell know it should be an eye and another should grow into a foot? It is impossible. There needs to be a blueprint, an energetic blueprint. It is all revealed in my book "Simply Healthy".
Such a brilliant eloquent and caring human being

Mate, those instruments could do with a lick of paint and a bit of a tidy up, while you are at it the ground could also do with a makeover. You may find it boring but don’t underestimate presentation. The people who pay for your projects are not all scientists, a little bit of cosmetics can go a long way.
Someone has bought a collection of seriously expensive and cool-looking sports cars giving these gibberish talks. People are so gullible.
Congratulations on catching yourself when you automatically described female Neanderthals as "he". Much of male scholars' teaching is suspect for this gender and also racial and species discrimination. But you're apparently capable of learning.
Since Neanderthals flourished for so long and then disappeared, so can humans.
As I watch dozens of these talks, I'm struck by the obsession of speakers, scholars, with how different we humans are from all other species. That perception is false.
"These guys" out the door? Beware making predictions, human.
All white males. So limited.
An alternative to out of Africa that at least can be made to fit DNA evidence is the hybrid theory, where modern humans arose elsewhere, Europe or Asia before Denisovan DNA flow. They migrated to Africa and bred with archaic ghost species giving rise to Africans. They bred with Neanderthals giving rise to Europeans. They migrated to Asia bringing Neanderthal DNA and bred with Denisovans giving us Asians. Those that got across the Wallace Line, more than likely carried a small amount of Neanderthal DNA (not sure on Aboriginal & PNG Neanderthal DNA % but this would be the process)and some Denisovan DNA. They encountered a relative large number of Denisovans compared to their numbers, and bred with them, or, they initially had a higher % of Denisovan DNA, possibly both, giving rise to PNG & Aboriginals.
yeah? where in 20 million square miles of eurasia are you trading 80000 acres of kenyan rift valley for?
@@AMC2283 kenyan rift valley isn't even the only place in Africa where we find early modern humans nor the earliest. My thought experiment came from Africans' having up to 30% DNA from an earlier archaic ghost species, thought to be most likely homo erectus, that modern humans elsewhere do not have. Meaning the interaction with the ghost species happened after the migration out of Africa, by modern humans that did not migrate and before Homo Erectus was extinct. Homo Erectus went extinct some 110k to 250k years ago by most estimates. Well before modern humans left. Although I note a small number of scholars, perhaps to cover the problem, now estimate the extinction as late as 35k years ago. Have we actually found modern human remains with DNA anywhere with no admixture from Neanderthal, Denisovan or Archaic Ghost species?
@@Damo-np7ul don’t want to just answer my question, you want to ramble? Will you feel happier if Homo sapiens arose where people you’re not prejudiced against live?
@@AMC2283 My answer clearly indicated your question was irrelevant as KRV is not even unique in Africa and not necessarily where modern humans arise anyway. Sorry I didn't rise to your bait or give you the answer you were hoping for. Stop strawmanning and projecting your own prejudices onto to others. Take off your "race identity" coloured glasses and you may appreciate an interesting conundrum.
@@Damo-np7ul yeah yeah, your prejudices refute nothing
When he said mallett does not know, he told me he does not know. Its like listening middle century Neuron dudes or they listening in their time to morons claiming Earth is flat or for that fact some current time people still claiming same. You can send information back on time. We just dont know how. But to claim we cannot when we don't even know how all the works is just nonsense. So talking garbage about dr mallet is just garbage on himself. We dont even know what live is or where we came from or we go. This guy for sure also things there is nothing after death and that we just came by some change out of mud, And things that answers the question when he does not even know what mud really is or for that matter any stuff. Guy the truth is that the entire universe is in fact a time loop. We are all, the whole universe is, locked in a time closed loop. It's just the loop is so big that it takes the whole period from the big bang or creation of this universe to the big crhch of destruction of the universe for the loop to repeat, for the whole universe to repair. And so already all were here and just keep looping with the whole universe where end of the universe is again it's begining. You guys were here already over and over reading this.
Man listen, black holes are portals into the past, the future and parralel universes as well as higher dimensions. By higher dimensions i mean the place we were before birth and return to as we die. Same who experienced near death experiences were there. Its not a coincidence they see a tunel with a light at the end which is same you would see past the event horizon when. Entering a black home
Thanks of very nice lecture and greetings from 🇫🇮
This was fantastic! Thank you
This talk seems very dated. 7 billion was the population in 2011.
The lecture was in 2012.
Yes, but published here only a year ago. Instead of "This draft sequence yields important new insights," I would have put out a disclaimer to the effect that some of the information presented has been superceded.
@@Paulus8765 You're right. Especially for sapien's DNA in Néandertal. If I'm not wrong we gave him our Y and mt chromosomes.
