What an absolutely lovely guest! I don’t understand how she can sound so calm and so excited at the same time, but I’m here for it. Thanks for sharing such fascinating insights!
Lisa (and David) is a joy to listen to. What a treat to be able to hear into the minds of those who are doing such wonderful science. Learning about their passions is an inspiration, with each and every interview. Their thoughts and insights never fail to leave a lasting and thought provoking slice of their own flavor of fascination in my mind. Thank you David and Cool Worlds for illuminating these captivating scientists who dedicate themselves to moving our understanding of reality forwards through their dedication and hard work. Your content and your approach to topics with your wonder and intellect truly nourishes and grows my adoration of the sciences as a layperson from the IT world. I genuinely look forward to everything Cool Worlds related.
Awesome we are being spoiled with 2 episodes of the Cool Worlds podcast in the last few weeks 💙👍 thank you Ps. Professordude you starting to look real ripped good job 🤟
David, I admire your integrity. Keep it up. Watching your podcast with Dr. Kaltenegger compels me to advise you to read Nick Lane's "Life Ascending" if you haven't already. It ties in with the challenge of defining bio-signatures. Life is physics at the molecular and atom level.
The coolest thing about Venus is that a system like ours can develop MORE than 1 Earth sized planet in or near the habitable zone. How she can have any respect for the science "journalists" out there is beyond me. Excellent interview!
this is truly amazing. lisa is a phenomenal communicator and i need to mention how cathartic and simply pleasing to the ear it is to listen to her speak so calmly yet enthusiastically on this subject. i thought you were one of the few who had mastered the art of a relaxing but energetic cadence; i’m delighted to have been wrong.
Very much enjoyed "Alien Earths" book. It really peaked some curiosity about the biosignature of extremophiles. I read the Surface Biosignature paper, very interesting how the biosignature spectrums were obtained. Wondering about the possibility of exoplanet life in anoxic hypersaline pools?
Actually, according to at least 2 more recent studies, we know that animals existed on earth not just 500 million years ago but 1.6 billion years ago, from fossils that were harder to identify because organisms were more squishy back then, and bones are more durable.
As an engineer I remember learning about interferometry by reading about the Darwin mission. I was especially excited when the event horizon telescope used the technique to take a picture of a black hole.
I agree with John Michael Godier on Multicellular Life evolving from Single Cellular Life (Prokaryotic to Eukaryotic Life?) being the largest Great Filter. Then large brained land life with opposable thumbs, perhaps. I'm starting to believe large O2 concentrations & combustion & the ability to smelt metal on land are prerequisites for most Technical Civilizations. These Great filters among dozens more may render Technical Civilizations exceptionally rare.
I believe that JMG has changed his position on multicellular life being a great filter. Think it was about a year or so ago, and think he's mentioned it in passing on his channel as well as Event Horizon. Some new research came out indicating that it was actually a much easier change than originally thought. I think a big hurdle is when life evolves. We are at the tale end of Earth's habitability. In 100-120 million years the continents will have reformed into a mega continent making much of the land mass uninhabitable. By the time the continent breaks up the planet will be becoming uninhabitable from the sun getting hotter 😬
I love JMG. Something I always think about is maybe specific extinction events long, long ago and us existing at the right time for that to equal fossil fuels may be what is rare here. Without them you have a huge hindrance, not to life, or even intelligent life, but to having an intelligent civilization with enough technology that we stand any chance to ever see them. Propellant and plastics truly got us where we are re: space exploration
You got her all interview! Then she smashed you last min!... This was interesting in the sense of a collision of perspective of minds and not what institutions one is from but one of who is hosting!
Here's hoping that the Colussus dedicated Planetary telescope is still on the table from Jeff Kuhn. It will be able to directly sample habitable worlds at a fraction of a price as the Next Gen JWST successor.
Great Podcast, technical question: When it was mentioned that the Methane spectral line does is not able to measure all of the Methane, are you really saying that for that line, it is optically thick ? If so, is there an Isotope line sufficiently strong but optically thin so that one can get a better idea of the Methane ? How about interviewing some time Sara Seager ?
It was an interesting conversation except that I think to much effort is being considered to life as it is on earth at this particular time and place. I think biological evolution and its resilience is being confused with the conditions necessary for abiogenesis. I would say that while its true almost all stars have planetary systems we have yet to find one like our own. And even in our neck of the woods the Earth - Moon system is unique as well. As with so many other factors that made the abiogenesis possible here. I agree the numbers on the probability for life other than ourselves are absolutely astronomical but I also take into account that the probability of the occurrence of abiogenesis might be a number so infinitely small that we could be alone. I agree with you that we have to keep open unclouded minds because the real answer is we just don't know.
I used to be extremely optimistic about life elsewhere in the universe (I blame growing up watching Star Trek), but have become more and more and more pessimistic the older I get. My view has become: if the answer is even just there is no other life in our galaxy then we will never know. We'll just keep doing what we do now which is "ah, but..." everytime another pessimistic result is returned. If the answer is "no" then there will always be a get out clause (but we haven't looked here, we need a bigger telescope, we're using the wrong telescopes, we need a $30B telescope etc) to cling on to. So, I'm going with that anything outside of our galaxy is probably out of the question - too far away to measure - and I'm assuming there is no other life in Milky Way at the same time as us. I'm even becoming pessimistic we'll ever get out of the solar system. The issue with red dwarfs is not the colour of the sun. The problem is the tidal locking stripping rocky planets of their atmosphere, hurricane winds, frozen atmospheres. I assume this is why the results for the atmosphere for Trappist-1 planets in the habitable zone is taking so long. I assume the results are pessimistic, and people are focusing their hope on them, and the results are going to create a lot of media interest. We need to move on from red dwarfs. We need future telescopes to inform about yellow and orange dwarfs. Until then, red dwarf systems will start chipping away at the hope that was discussed in this podcast
In the end of 1800's a US billionaire sponsored the first US astronomical observatory in return for it to bear his name. You can be clever and appeal to billoionerae vanity.
There will always be alternative explanations for every potential detection of alien life in an atmosphere so will never really know unless we go there.
Oh the US and our little oligarchy. Yes, we somehow pulled off Webb unfolding, why take that chance again when several far less finicky and overwhelmingly more proven craft can do the same job? Hmm I wonder why Northrop would want that kind of contract instead..?
Lisa Kaltenegger claims to be Austrian but she seems more half South Italien (see the constant use of hands) and half Norwegian (see the slow movement of the hands).
When talking about how life began isnt it quite plausible it actually started in another solarsystem and was allready hitchhiking on the asteroids/rocks that formed our planet. Especially considering from what i have understood there were far more solar systems created a 6 billions years back in the than there was 4.5 billion years ago when our sun formed, that should mean statistically more chances for life to form then. It would also give more time for the complexity of life that we see to evolve if it didnt have to start from scratch here and instead had a few billion extra years of evolution
Try Listen to Jason Breshears ! The - hands down - greatest chronologist to ever have walked this earth ! He can tell you a thing or two about DATES, Kalendars , and Ancient History - Not the usual Billy Carson /Graham Hanckock Atlantis balderdash drivel -'
LIKE Gábor Szabó. I always said that In 90.percent of cases one or both people want to disconnect , usually at least one and thus is just a good excuse... here no ONE even told THEM to, give me a break.YOU ALL HAVE no idea what WENT down...on its face the dad has SOME BULL SHITTTD STORY about rejecting the kid because of a flight of steps and he's felt guilty all THESE years. ..and who knows if he didn't cheat on the women who THEN divorced him
My take on the rare Earth possibility (apart from the fact that I think all things are possible - that's the state of our measured knowledge right now) is on the matter of Responsibility. If life is rare, it could be rare enough to only have happened here. (There are no real statistics, so that's the kind of possibility we have to settle for). So what if that's the case? That means (to me, anyway) that there's a natural Responsibility on us to take out the insurance policies life needs. (Because if life itself is this rare, our kind of intelligence is already proven to be incredibly rare - unless the previous civilization used something as primitive as buildings, and these all got turned into glacial morraine or something.) One of the many possible scenarios is that we're the only intelligent beings ever, and if left to chance, will remain so. That means "It's Up To Us". If intelligence as we know it (or "to this level" in stranger ways) is everywhere, there's nothing "mission critical" about our missions of discovery, and quests to explore and extend. There's "someone out there" who's got this. Relax. It's all just a game. All you're doing as an astronomy is repeating some version of the progress the nearest million year civilization made in their early years. And you're the millionth (just to give it a big number) to do this. Once again some beings discovered the items on your intellectual checklist that take a civilization beyond something like astrology and "little stars" that twinkle twinkle "in the Sky". As a game that's nothing to scoff at. Must have been fun for us to get started like this without guidance. Well done. Bing bong High Score, Play Again? However it's different if we're what will either become the million year civilization, or dinosaurs whose bones will never be examined by a being like us. Responsibility. I think we need to at least behave as if we're the Caretakers - or even the Foster Parents of this Earth and those other Earths etc. Until we have data, it's all up to us. And it's a game, too, hey? And it's maybe good enough if it ends up just being a game. Great game. Makes life fun. Life is all very well and quite nice really. But Fun is Better?
SpaceX's Starship will revolutionize space-based telescope science and engineering. It could have launched JWST unfolded. With the minuscule launch cost compared to existing rockets and much simpler telescope engineering, you could put literally a constellation of JWSTs out there.
The diversity of life. You are in love with DEI and every campus/institute is scrambling to show it is more woke than the next. It's easy to see why there is such a bias toward the Carl Sagan view. However, let's examine how the diversity of life actually works to prove it's trunklike origin rather than a much less likely bushy tail. Since we know life is resilient, can emerge in all different kinds of environments and can't easily be sterilized away.....................................how do you explain all proteins being L? Surely, if R proteins were possible, they could emerge in all the places L proteins can emerge and couldn't be easily sterilized or outcompeted away. It makes sense that there are only 4 bases in DNA and RNA has a fifth, because all the life that RNA and DNA creates can outcompete even slightly less fortuitous or advantage life, but even Archaea have RNA and DNA of the same molecular composition so if life emerged twice, it would have had to have done so prior to archaea and been outcompeted into complete extinction. But none of this explains why all proteins are L. Further, if you manufacture proteins they are both L and R in equal measure. That seems like very strong evidence life didn't start too many times and most likely just once.
Billions maybe trillions spent on other planets and that's ok? why no live stream from the moon of our home planet earth? technologically not possible? No interest after thousands of years of wondering what our planet looks like from space, a few pictures from the moon etc and thats it? Two cameras please live streaming from the moon, one in zoom mode i think would be incredibly interesting especially to children! Strange?
Why are you so anti-life; intelligent life & advanced intelligent life in the universe? Is it because you as a scientist are afraid to step outside the safe, sterile world of academia & university don’t dare think outside the box syndrome? Albert Einstein said, “Imagination is more important than knowledge.” Think about Einstein’s words, perhaps then you as a scientist will open your mind to expansive thinking.

Fantastic, bought the book. Thank you David for introducing us to your terrific guests.
U are both very impressive Lisa and David and in a kind of, 5th element way, persuasive. A joy to listen to and see such a lucid dialogue.
Simply a superb conversation. A must to understand current search for biosignatures out there

I love this stuff. Please let their be life out there and let's hope they are more enlightened and further on than us.
There is. They are
Im more and more skeptical about intelligent life, moreover I don’t even know if we should hope for some other civilisation… we will see
Just finding the podcast channel now. What a treat. Additionally it was a pleasure to hear from Dr. Kaltenegger

Very well stated. Agree with you 100 %

There are 750 US billionaires... why isnt even 1 sponsering the build of space telescope for humanity
They are billionaires... probably extremely greedy and motivated, and ego driven.
Look up seti, breakthrough, these are being funded by billionaires. Also blue origins, spacex are enabling space exploration
There are starving people and diseases which they could also fund - probably more deserving than a fucking telescope
Check out Yuri Milner and the Breakthrough Starshot Initiative

The key to life depends on whether a planet can produce the fifth dimension at its center.

Yes
