Geoff Marcy has been a pioneer in the search for extra-solar system planets since the first discovery of an exoplanet surrounding a main sequence star was made in 1995 by Michel Mayor and Didier Queloz. Within months, Marcy and his team had not only confirmed this result but detected numerous other exoplanets. Seventy of the first one hundred exoplanets were discovered by Marcy’s team, including the first exoplanet located as far away from its star as Jupiter is to the Sun, and the first exoplanet discovered by observing the transit of its host star, a technique that will be used by JWST to explore the atmosphere of exoplanets to search for biosignatures. Marcy was then a Co-PI on the Kepler Mission, which discovered over 4000 exoplanets. For their pioneering work in the creation of this new field, Marcy and Mayor shared the international Shaw Prize in 2005. More recently Marcy has turned his attention to methods to probe for intelligent life in the Universe, first as a PI on the Breakthrough Listen Project, and more recently exploring novel methods, including optical techniques to probe for possible signals of intelligence elsewhere.
Lawrence and Geoff discussed all of these exciting topics and Geoff’s origins as a scientist in a thoughtful and fascinating discussion. He has become well known not just as a world-renowned scientist, but as one of the best communicators of astronomy there is. This discussion will give a whole new dimension to your thinking about that age-old question: Are we alone in the Universe?

Reassuring to know there are still brilliant, sane humans on planet Earth. Thank you, Lawrence and Geoff.
It's wonderful that Geoff Marcy is willing to speak about his bout with mental health. I've discovered a planet with life on it that doesn't do that often enough.
One of the best takeaways from this interview in my opinion. We often think these super smart people are somehow impervious to these issues, so it’s refreshing to hear about Geoff’s struggles, because we can all relate to some extent if not completely.
This has been a brilliant conversation on the history of exoplanet detection, I really enjoyed this interview by Lawrence, one of his best. Geoff is a remarkable Scientist. Big respect to both these men.
They talk about space as if they been there, and jerk each other off about how much they "know" about space. The reality is, Space is for nihilist nerds. You arent going to space, no one you know is going to space, and no one they know is going. Now go hit the gym, work on yourself, and make life better here on earth for you and your loved ones.
I wrote my final astrophysics paper based on work done by this man. What a wonderful conversation!
Geoff Marcy has piqued my interest in astronomy for decades. He’s a treasure, both as a researcher expanding our knowledge of the universe and as an ambassador of the sciences to his fellow human beings. Thanks to Lawrence and Geoff for this interview and for all the wonderful work they both have done over the years!
Peace.
Such a humble man. Great conversation and very informative. Thank you, Professors
Carl Sagan was one of the great enlightened human beings of the 20th century and his " Cosmos " series continues to have profound impact on us today in opening up awareness of the awesome universe we live in and the responsibility we have as stewards of ourselves and all life on our world !
Brilliant, so enjoyed this. Loved the 'Hitch Hikers Guide' reference too!
It's great to listen to two bright and open minds talking about actual facts and what still remains to be shown - so enthusiastic. I immensely enjoyed it even though I am not specialised in this field. It makes you wish for more frequent public discussion of this type. Thank you!
Actual facts? Yeah, ok
@@Delphius- Reference was made to the physical and chemical facts, of course. I think the two made abundantly clear that natural laws will also apply to extraterrestrial environments, but that life itself may be quite different, e.g. in terms of energy generation, etc.. So, developing scientific hypotheses on the basis of such facts is, in my humble opinion, quite interesting and justified. But you seem to know more or have understood it better. I am just a biochemist and lawyer, i.e. not the expert that you seem to be.
Geoff Marcy is indeed a wonderful teacher....a wonderful translator 😊
I really enjoyed this interview! Thank you Lawrence!
Geoff Marcy came off as a very likable guy! There’s a thousand things I like about this interview! 😀
I have definitely begun to appreciate Lawrence’s contribution to these discussions. With much history and knowledge to offer he is able to tease out information from the guests in a way that probably makes it way more interesting had the guest been left to ramble on themselves. As a Christian I also appreciate his acknowledgement of the ‘spirit’ within the last 5 minutes of the podcast. With evidence of biology outside of earth sitting at ZERO, how is there a field of study call Astrobiology? LOL
A great documentary. I wish everyone in America could see it. Every classroom should contain these issues.
I strongly agree!
I hope you'll consider inviting Avi Loeb on your podcast! Quite famous theoretical physicist, who has a lot of interesting stuff to say on extraterrestrial life and intelligence - the discussion would be great!
Avi Loeb is an obnoxious raving nutjob
So nice to see Geoff Marcy sharing his insight on this subject, there's no one more qualified imo. It's sad that we lost his voice for so long but hopefully this isn't a rare appearance going forward.
This is going to be awesome 💙.
Extrapolating exo planets is super exciting.
As with your interview of Alan Guth, it is incredibly illuminating to see the decades-long story arc of a scientific field through the lens of the career of a first-mover in that field.
Very interesting interview. We earthlings are limited to our Solar System. The stars we see from afar. Life existed on Earth for over 4 billion years. For 500 million of those years Earth experience large asteroid/rock-chunk bombardments. That means that chunks of Earth with microbial life were flung into all parts of the Solar System for 500 million years - to Venus, Mars, Jupiter, Saturn, and maybe even Neptune.
Thank you Geoff and Lawrence, wonderful conversation and rich in subject matter.
Yet another incredibly informative discussion..
The idea of clusters of galaxies is mind blowing
Great interviews
I am smarter after this fantastic conversation.
Helo Sir! I am long time big fan of You from Poland if I can put it that way. I am fan of Your beautiful inteligent great mind from times when I first discovered Your and Richard Dawkins fenomenal discussions/lectures. You teached me and opened my mind so incredibly and provided me with such fantastic knowledge that I must thank You so much and just bow to You for everything! Thank You for every fascinating talk and lecture! At last my favourite subject Exoplanets! 😊🙏I send You and Yours big hugs and much love! Take care Sir! ❤
Thanks, gentlemen, for that enjoyable and informative discussion. Two of my favourite scientists on top form :)
Genius! Both of them and this podcast.
Thank you so much for the podcast. Great interviews, great teachers always….
Pretty cool watching two twins do a video
Again , thank you for your channel - and those that you interview . ;)
Weren't the first extrasolar planets discovered actually part of the Lich Pulsar system in 1992? The planet that Mayor discovered (51 Pegasi b) was the first exoplanet around a main sequence star but not the first exoplanet overall.
Thank you. Fascinating and realistic discussion. Science is blimmin' amazin'! Creativity, perseverance and critical thinking.
Fascinating topic -and Krauss is an excellent, if stylistically different, presenter / popularizer of science in the tradition of Carl Sagan. While the likelihood is high that intelligent life exists elsewhere in the universe, for reasons of its probable rarity and factors of time and distance, it's highly unlikely that we on Earth will ever find evidence of it, barring investigational methods that don't now exist. That said, we must keep looking, listening and innovating.
So excellent!
1:28:01 Thanks for all the fish!
Does Dr. Marcy have a RUclips channel?
Brilliant show.
its interesting how most astronomers see humanity as one family.they should set up a kindergarten for rogue politicians.
A podcast between predators!!
Dr. Krauss makes an offhand remark at 13:46 that Carl Sagan's work on nuclear winter "was probably wrong." How so? What is our best current understanding of the aftermath of a full-scale nuclear war?
Basically it would only affect first world countries dramatically. The third world would be hardly affected, though there are unknowns like long term effects of radiation and fallout etc. There are papers out there. But bottom line is hundreds of millions dead, not billions or human extinctions as implied by old scare stories.
46:28 this is the equivalent of being able to time Usain Bolt running the 100metres from a dozen lightyears away.
That's if Usain Bolt glowed with the power of an average star, but still, that's quite impressive.
Sending astronauts is about learning how to live in space.
..dr. Marcy, eh? are you by any chance related to Marcy Darcy?
Due to a hair study that I do. Always I think when I see people, that people cannot figure out the basics; why people losing hair, but they are going to tell me about planets located billions of light years away or hundreds of light years away and they want me to believe.
I was totally engrossed by this discussion. I would like to point out though that when Krauss said that there is most likely hundreds, if not thousands, of planets with technological life in the galaxy RIGHT NOW, he really opens a can of speculative worms. There would almost certainly be ONE such civilization that would be so successful it would expand over the entire galaxy. In fact, that would have happened billions of years ago, and that civilization would have extracted all the raw materials it needed wherever it found them, i.e. the Solar System we live in -- we would not be here if that was the case.
Clearly that did not happen. There is something preventing that from happening, and we are going to find out what that is soon enough.
It is so disappointing that we know so little 😕😢
How do we know what we don't know? We know so much more than we did a thousand years ago we can't even fathom.
LK great podcast but another example of you talking over your quest.
Sending people to space is a stone age mindset. As Martin Rees argues, it shouldn't be done by tax dollars. Leave it to the private companies.
We have been promised commercial space trips to the public for 40 years. The amazing brilliant and totally advanced 1960's technology was lost, and for "some reason" we cant build it back, nor can any other nation. Only time in official history we lost technology. If only we had that very totally real 1960's computers that took us there (that apparently had less computing power than a digital calculator).
Strange stuff.
The amount of absurdity in this video is humorous. Too smart to have any common sense
Krauss talks too much. I wanted to hear more from Geoff rather than listen to his monologue
Geoff got a bum rap. It's never a good thing when science throws away top talent because of destructive zeitgeist.
Genders?.
Are they not social constructs, not scientific facts?
@@thegroove2000 These guys may be brilliant in their fields, but crippled and ignorant of their own "socially constructed" ideology. Geoff's former Elementary school in the San Fernando Valley is all about DEI, but failing to teach math. His alma mater is well below average at 30% grade proficiency.
@@nuqwestr I have also noticed.
@@nuqwestr They forgo science for social constructs that are politically motivated agendas. I cant trust or respect anyone like that. It's a conflict of interest and a sign of being two-faced.
Exoplanets do not have genders.
Geoff, your Plummer Elementary School has below average test scores and below State average in Math. Your ideology has failed and the system is worse, not better.
Saying that he got a good public education is not the same as saying that it is still working well today, is it?
@@BrianHill Listen to the beginning of this video, he deprecates and apologizes for being from the San Fernando Valley. He grew-up in the very center of post-WW2 prosperity and hope for the future, it was a paradise neither of us appreciated or understood, but is now gone, and because of the very political and cultural policies he stands for. His former elementary school is no more diverse now than it was 60 years ago, just flipped to a different majority demographic. I checked, so can you.
