[@alexisgarcia2458]

Amazing topics, thanks Lex ❤

[@eddox33]

When David Grusch?

[@realNormanSmith]

Your interviews are the best!

[@Dsksea]

If you end up interviewing Jeff Bezos please ask about his thoughts on AI. He has a lot of insight.

[@Ottee2]

Hi, Lex, please disregard my earlier suggestion, a few months ago, when I said you should try to get an interview with Henry Kissinger.

[@___ruthless]

She is a proper scientist. Humble, measured in her responses, full of caveats, and has respect for others who don’t think in the same way as her

[@timothygumenik726]

I gotta be honest she’s not what I expected. Due to her intelligence, fancy degrees, I thought she would be more arrogant? If that’s the right word.

[@Truffle_Pup]

I have to say, I was utterly blown away by this one Lex. I only wish we got another hour or two out of this discussion with Lisa, she is utterly fascinating and speaks so easily yet incredibly succinctly.

[@opurion]

there are a few clues she may have been under the weather and not been up for chatting for longer

[@DanielBro42]

never seen the word "succinctly" thanks

[@thomabow8949]

I think the romanticized questions Lex proffers aren't exactly proper questions to ask an empiricist, like a physicist - half of the time, you'll get a professional opinion, which seems bland, the other personal speculation@@opurion

[@dave4148]

utterly

[@stephenscharf6293]

Yes! Please have her back, Lex, for more discussion with Lisa. Outstanding interview.

[@DrRussellMcConnell]

I greatly appreciate any scientist who can say, "We have no idea" to a question. This is where humility gives room for discovering new things.

[@Colleen1976]

Lex can we please get a couple more hours with her. This is not enough.

[@NinjaofApathy]

Hey Lex, I'm glad you decided not to use a "teaser" intro clip of the conversation, I dislike starting a video and having direction of conversation and concepts spoiled, plus kinda a time waster since I now have to listen through that segment twice, once out of context. Thanks for all you do, love ya Lex :)

[@shanebruce3997]

I may be late to the game - just discovered your podcast - thank you! I love the Lisa Randall quote, "I probably don't believe in God. I think it's a problem that people are considered immoral if they're not religious. That's just not true. This might earn me some enemies, but in some ways they may be even more moral. If you do something for a religious reason, you do it because you'll be rewarded in an afterlife or in this world. That's not quite as good as something you do for purely generous reasons."

[@alexandernahan6768]

I think she's just saying how people instantly think your immoral for not believing in god. Shes not saying that its what others believe

[@Openmindallthetime143]

How wonderful now u can check all his timeless pieces he's done . They are really all wonderful lex is extremely open minded and so are his guess . Welcome to the crew!

[@phillipcook3430]

Sounds like she knows more about the physical world than the spiritual. I am part of the religious community and I am not aware of any of my community members believing that those that don’t believe in a religion are immoral or more immoral. In fact I know many religious people that are more immoral than some of my agnostic or atheist acquaintances. This lady needs to get out more if she wants to make such a generalization as she did.

[@etmerde]

Thanks for saving me the time

[@AECommonThread2137]

Not necessarily. I see your point - and I am pretty much non-theist/agnostic (I don't like to label it) - but many people's religious or non-religious attachments differ from one another. I can understand why many intellectuals, scientific types, and atheists hate religion - especially considering a lot of the historical attachment that has had such a dramatic impact on humanity and the earth - however, I believe that the approach most of them take is far too damning against those who follow. I find that if we push too hard to impose our ideologies on another only push them further. I think an analogy is how strict parents who are overbearing on their kids will only push them away or cause them to rebel - people want to have agency of their views whether right or wrong. If one has a point of view to impose, I find that leading by example, and finding a way to bring a common thread to the table can help homogenize the polarized ideologies. You can see this notion everywhere from polarized politics, wars, religion, academics, poor and rich, enlightened & ignorant, etc. My fiance is catholic, but she has her own interpretation of faith - she has her own walk with "god" However, doesn't subscribe to a lot of the bigotry, pseudoscience, and bastardization that idols, the Vatican, and abusive priests, popes, molesters, etc. That involves themselves. My fiance does good to others not for the afterlife, she is a true empath - she doesn't do it to please, but because she feels the common thread in us all and finds it a virtue to be kind. Faith can be great for a society, however, it has many flaws. Due to my antitheism, it is easy to fall nihilistic and I need to propagate meaning in my life - sometimes I am jealous of the will that those with faith have. I wouldn't have it any other way though - I enjoy finding out, being the tool to my own will and happiness, and I love my partner and her beliefs as we continue our 8-year relationship with our outlook on life. Sorry for the rant, I thoroughly enjoy writing.

[@idatong976]

Thank you Lisa and Lex for this episode on science and physics. It certainly sparks an interest and my curiosity now wants more. For sure, I'm still in awe every time I look at a sunrise and a sunset. The beauty doesn't stop...

[@resevoirdog]

Watch out because he will block and purge you if you criticize him. He's crazy lol look at people's experiences with him. Dude is one of those "free speech for me but not for thee" types

[@nicholasward6203]

One of my favorite episodes to date! Lisa, speaks so brilliantly elegantly.

[@PurnamadaPurnamidam]

Lisa Randall is a remarkable example of a brilliant and creative scientist who has advanced our understanding of the fundamental nature of reality. I admire her for Sakurai Award and her book Knocking on the Heaven's door. Thank you Lex. ❤❤❤

[@summaryjudgment]

I've been waiting for an episode to actually be about science again

[@ShonMardani]

You need to wait forever, no science out of book writers (copy and pasters) or from science communicators, they are salvaged cars.

[@resevoirdog]

Just don't be critical or he will purge you. Lex is anti free speech. Look up his past actions from people who know him. Dude is a monster

[@charlesackman892]

summaryjudgment I totally agree with you. I get sick and tired of one way philosophy being dictated to me. I hear a lot of opinions on these presentations, but yet to see one person add 1+1=2 much less the intricacies of Jordan algebra.

[@JustAnotherGamertag]

Reading Lisa’s book “Dark Matter and the Dinosaurs” literally saved my life. Depressed as one could be, hurting myself and hating myself. I read that book out of pure attraction to the idea of two completely disparate things being connected in some way, even if it was in tragedy. The book completely reopened my eyes to the curiosity one could have about the world. That’s all it took.

[@Koort1008]

All is an appearance appearing to an appearance that appears to appear.

[@TheRealStructurer]

Nice conversation. Wish it would have been longer!

[@maremare1655]

Lisa is a good teacher/speaker, great interview and she looks amazing at 61.

[@jannichi6431]

She's doing A LOT correctly. 61? TY, didn't know. I truly thank Lisa and Lex.

[@billybobinthehouse12]

You know. I've never met someone who's really into their physics to this level. I find they are very interesting people and want to hear more from them. Thanks Lex for finding alot of interesting people that I never get to see in real life 😊

[@peterk2735]

I used to attend a math class in in uni while studying informatics, the guy sitting next to me was an astrophysicist. He’s now in charge of one the biggest observatories in the EU. I’ve never met a more intelligent, knowledgeable and thoughtful individual in my life. People like that are one in a million

[@bozinoski]

I don’t know how I’ve never hear of Lisa. Her knowledge and her way of thinking is impressive.

[@ac-gp3kz]

A short and sweet conversation. Would like for it to have gone on longer.

[@346rt]

Lex.. great work. I’ll be tuned in regularly. Thank you very much.

[@jonathancamp7190]

At 24:25 Lisa stated that she toured the Museum of Nuclear Science in [Abluquerque, New Mexico, USA.] She further stated that the nuclear weapons "looked really cool." I've toured the museum myself, and from an aircraft mechanic point of view (both maintenance and assembly) I found it fascinating how wonderfully those things are put together. The panels all match up perfectly. The rivets and safety wiring are all done to perfection. I've never seen higher-quality workmanship on anything than I did observing those artifacts. My hat is off to the people who assembled them! I find it an interesting juxtaposition to think that so much quality workmanship went into something that's only going to fly once and blow itself up at the end. By the way, I really enjoyed this video, and think that Modified Gravity is the solution to Dark Matter/Energy.

[@vermeerasia]

I don't get it, a Lex podcast under an hour in duration...was this just the trailer for the soon-to-be released actual podcast with Lisa Randall?! I didn't even have time to get my popcorn ready before this one was over...

[@sarthakpatnaik714]

Thank you Lex for adding volumes to my reading list every week.

[@SwapnilBhartiya]

The saddening thing about humans trying to 'define' the universe is that our own science and perceptions are very limited. Our limitations makes a sad realization that we don't know most of the existence around us.

[@peterk2735]

That’s why one of my favourite sci-fi books is Solaris by polish writer Stanislaw Lem. He shows how our human senses are not enough to comprehend the vastness of the universe.

[@justinpridham7919]

Deduce is a fancy way of saying it is made up. They will never find dark anything. She is wrong that gravity is a force. Too many physicists compound the problems with our current understanding, deductions based on mistakes and misunderstandings. Right from the beginning of this chat she lost me.

[@billc7480]

Well this is an amazing surprise for me. I read Lisa's book Warped Passages when I was younger and she's been one of my favorite science writers ever since. I always look forward to her books. I wish you had more time with her but this was great!

[@frozenfremen4949]

Dear Lex, I always enjoy your podcasts - and more often than not, it is your own input, your own wisdom, your own humanity, that interests and touches me more than that of the person being interviewed. For me the star of your podcasts is definitely the host himself 🙏

[@Starship_X]

Who knew Jodie Foster took her role in the movie Contact seriously in real life.

[@michaeltravis3562]

Wow, Lex! When she goes into her general overview of the standard model of particle physics- it's poetry to my ears. Her efficiency and choice of words is refreshing. She breaks it down into lay terms as good (or better) than anyone. Personally, I think she interfaces better those who are well known for this sort of thing (Brian Greene, NDT, Sean Carroll, Brian Cox, et al). It's good to see her get this sort of attention, because it's deserved. One of your best guests, Lex! (applause button)

[@BeyondTheTwo]

The depth of knowledge and the level humility from her is just impeccable 👏🏾👏🏾👏🏾

[@kinnaribhalerao8112]

Amazing one lex! Would have loved to hear her talk more! Hoping for a round 2!

[@computercrack]

Love the Intros /Outros with this calm voice! Could listen to this all day.

[@aloeiciouss1]

I love her statements about physics forcing us to question our immediate intuition and consider difference scales and distances...so beautiful. I'm using her statements in my high school class.

[@lmelin1959]

Very interesting conversation. Thank you to both Lex and Lisa for sharing this with us.

[@klarad3978]

She’s a fascinating person,y only complaint is that it was too short, a couple more hours would’ve been amazing. But regardless of that, it was truly inspiring and humbling to listen to Lisa talk about our wondrous universe and the underlying physics of it.

[@agrayday7816]

great interview wish it was longer, less than 1 hour is not enough time. :) you should have her sister on as well with her together. :)

[@donsnicklefritsrickles1142]

Twins Basel! Twins!

[@jdwoods2008]

"That's a lot in a 'relatively' short time" was pun of the century and not even a smirk.

[@777ouivous]

much gratitude to both Lisa and Lex for giving your valuable time. I too wish it would have been longer, hope we get a round II. ). Peace and Love

[@drlohewitt1]

First time listener to this channel or podcast. The interviewer and author combine their unique gifts to bring a fun and inspiring view on big question, or unknowns, or worries. The conversation is relaxed and comfortable yet fascinating and exciting. For me, this interview brought a measure of hope and optimism to my day . Thanks to both of you!

[@StarTreeNFT]

She is one of the most brilliant individuals I’ve yet encountered!

[@alvaroluffy1]

sad this only was 1 hour, hope she comes back

[@purplmnTTns]

You’re a total (dapper) bad ass, Lex! Thanks for all the mind-blowing, soul-illuminating, heart-expanding conversations. Grateful. ❤

[@stephenscharf6293]

Just an outstanding interview with Lisa, Lex. I love her ability to be discuss very specific aspects of Dark Matter, Theoretical Physics and then "generalize" up to a higher "Level of Abstraction". As some who spent many years teaching "complex stuff" (DFSS) to my fellow PhD-level scientists & engineers in Biotech, I learned that the ability to move up the _Ladder of Abstraction_ helps drive true insight and understanding. Please have Lisa back for another interview. Cheers.

[@MichaelIlesCremieux]

Thank you Dr. Fridman. Lisa Randall is incredible.

[@zyxmyk]

That was so good, I watched it twice. I thoroughly enjoyed listening to them.

[@JollyRoger183]

I saw her live in 2006 at a science conference in Venice. Daniel Dannett, Steven Pinker and Peter Atkins were also there. Was really exciting to hear them discuss ideas after their presentations.

[@Mrbfgray]

She looks way old by now, time isn't kind to any of us. lol.

[@tallbudha]

Wow, What a lineup. Wish I could have been there.

[@jannichi6431]

Thought the opposite. She looks great. Remember the 'arm that talks'. She's beautiful.💕🎆🌌

[@JollyRoger183]

@@tallbudha Marc Hauser was also there. Fascinating talk about moral issues. He later got into hot waters with accusations about data manipulation at Harvard.

[@icenarsin5283]

You are the best interviewer on the planet! I don't think you have any competition,

[@Koto137]

Finally some space/physics episode, thank you!

[@xdisruptor6630]

Lisa is a wonderful teacher: "Being a scientist involves believing strongly in things you're questioning and casting doubt on very deeply, all the time - this is a very tight rope to walk on every single day" wow just wow what a wonderful well-spoken honest and brilliant human being!

[@KingsMom831]

Thanks for another FANTASTIC episode!

[@trebledog]

I love listening to Lisa Randall's views on physics, the cosmos, mathematics, and everything else. She's at the apex of the most interesting women in the sciences and the world at large.

[@hapaart]

Lex glossed over a salient point, compression of mathematical theories into shorthand is beautiful, and, compressing particles into bits of information is too.

[@bryced5928]

I LOVE her! And I LOVE Lex . These fascinating brilliant, like minded people, Id never know existed if it wasnt for Lex. I'm so grateful to have discovered him and look forward to more podcasts and reading some of these selected books! To me LEX helps fill my days with positivity, hope, new knowledge, and wonder. Not too shabby!

[@mnrvaprjct]

Lisa Randall is hands down my favorite physicist - I want a doctorate with a thesis in brane cosmology because of her !

[@DrDeuteron]

Pls don’t waste your life on that

[@afz902k]

@@DrDeuteron can you elaborate on why, or what would be better doctorate choices in theoretical physics?

[@DrDeuteron]

@@afz902k I first learned of strings in 1987. I considered goin into them, which would have produced nothing useful in my career. Instead, I applied physics to mars exploration, quark science, deuterons , global radar cartography, and problems that we don’t talk about. Way more fun.

[@doc032848]

This was the best discussion of particle physics, dark matter, et aliter, that I have heard in many years. Lisa Randall is the most truly scientific speaker/thinker I've heard in a long time. She practiced both sides of the formula she proposed beautifully, that is, our pride in our progress and our necessary humility about its limits.

[@matthewprestifilippo7673]

She is great. Great interview.

[@fxbeckers]

I don’t think we should be all to quick to dismiss what has been achieved, without losing sight of the grander vision. The path forward rests on assumptions that have now been proven empirically. Hindsight is 20/20

[@johnwsimpson3153]

Fascinating interview, well done, Lex. I was hoping you would ask her about the recent findings from the James Webb telescope, apparently indicating galaxies older than the known universe. Regarding dark matter, could it be an error in interpreting the characteristics of space itself? Something that affects gravity but not the other forces?

[@jannichi6431]

Never forget the day when I learned Quantum thinking and multiple galaxies and possibilities of more senses👁️

[@resevoirdog]

Watch out though dont criticize lex in any way because he will block and purge you if you criticize him. He's crazy lol look at people's experiences with him. Dude is one of those "free speech for me but not for thee" types. Be very careful.

[@the_one_eyed_man_is_cursed]

Unsettling. Randall's absolute truths are proclaimed without wriggle-room. The rigor is so rigid as to expel all desire to debate her. Where is the necessary scientific humility? An open mind is alive, not merely analytical. Sagan would put his positions strongly ...but he allowed the unknown. In theoretical physics, very few theories age well.

[@ExaltedMediaInc]

Can't wait to watch this. I love the nerdy stuff.

[@tomalekrx]

Wish this was longer. Great conversation

[@martymcflyer8487]

10:29 Lisa tried to point out how fragile the earth is, Lex interjects that it's resilient on the grand scale -- her response which is probably one of the most politically impactful of the whole conversation is deleted. Will the extinctions of the anthropocene be something humanity can contend with indefinitely? Lex, Elon, Jared, all think so. No glowing praise ... doubtful Lisa will be invited back even though she's one of the smartest and objective people he's interviewed☹️.
