Lex, check Robin Hanson’s Grabby alien hypothesis Comment from : Akim Lavrinenko

5 hours is impressive I might put it on 2X speed Comment from : Jeremy Ghost

He loves his work! Comment from : Jeju Island Trekker

Could you imagine being an uneducated Youtuber and failed wedding photographer and ride that all the way to Lex Fridman! HAHA Comment from : jonlamontagne

2:01 Apollo also had a "milk stool" adapter for smaller Saturn 1B rocket test articles Comment from : Roland Lawrence

Tim, what Watch Face are you showing off on your Apple watch? It looks cool and I'd like to try it Comment from : Vincent Dermience

I'm going to save another 4h45' to watch the rest of this Comment from : Vincent Dermience

What a great interview! Lots of topics, condensed answers, new understandings Very good Thank you for sharing Comment from : Pedro Rafael

My daughter's fiancé at the time was a welder working at SpaceX It was a wonderful company to work for They treated the employees very well, until the day they had finished all their work and laid off everyone in a single day They were not up front when they hired everyone at the beginning that this was what they were going to do It was a cowardly move on the part of SpaceX management I appreciate Tim Dodd's enthusiasm, but SpaceX is no different from Walmart, Amazon or Meta when it comes to employment practices Comment from : Curtis Johnston

Lex, i never gave you credit before, but over the past few weeks ive really grown to appreciate your podcasts Thank you for what you do and please continue to do great things! Comment from : Josh Wright

What a great interview! Tim Dodd got this forty-year old nerd into another hobbyrockets baby! Comment from : robmaxi1

Joe's going to have to step up his conversation durations after this one Comment from : Michael Beckman

14:52br😂😂😂brTotally Comment from : Paul Redman

Catching bits and pieces, but this man does not want to be the first to use starship to go “orbit” the moon That businessman who bought the tickets rather artist/creatives die than his own family This man would rather just go to space in already developed/tested aircraft rather than a new rocket Not the human for this task Comment from : Vi

Lern a lot from Tim in last 3 years Comment from : Artin T

No way Dodd, Moon Landing is not the same as Mars Landing Mars has stronger gravity than our Moon, which means on Mars it needs more energy and maneuverability to land on Comment from : Michael

They can only go into low earth orbit lmaooo Comment from : Darkmaga1776

Anyone running for President should run the Fridman marathon Screw the intellectually insulting debate format Comment from : Conservative Mike

artificial gravity, thank about it we use it every day it's called Excelleration when you hit the gas pedal you can accelerate at one or any G, and by hiring the brake pedal you also are accelerating at one or any G spinning not necessary just accelerate at your desired G Comment from : David Wyatt

They probably stopped calling it re entry because they’re look at mars and the moon:) Comment from : barebare

everyone love a geek out! MADE ME SMILE Comment from : Yo A Kh

finally done, thanks for your amazing content Lex Comment from : Nicolás N Navarrete

I have attempted to meditate many times in my life and prior to this CD the only success I've experienced is with live guided meditation wwwyoutubecom/post/Ugkxzpa8CIfZcihW4Z0F_ja0QF3W9KIatrsq This is the first CD I've used that cuts through my unmedicated ADHD and enables me to truly relax and experience a quiet and energizing interval The instructors voice is very soothing and pleasant to listen to I am easily able to sit successfully through the entire CD, and for quite some time after I cannot adequately express how tremendously helpful this CD has been on my spiritual journey!! Two thumbs up and 10 stars! Comment from : dr man

Lex please get Dr Steven Greer on the podcast I believe what he is doing is extremely important! Comment from : Damon Morris

Great talk! I do feel like there's a bit of an opposition between getting "common people" engaged in science, and qualifying and adding caveats to what you're saying On the one hand you've got the scientists in Don't Look Up and the expert witness in the OJ trial, who fail to convince people bc they're adding in their uncertainty in a way that can be hard for ppl to really comprehend On the other hand, you have the "ALIENS!" dude and Avi Loeb (too harsh? maybe, but he has said several times that the astronomers should've barged into the White House screaming "OMG we're totally going to see ET with this thing!!!!!!11!!") There's a lot of middle ground, and we really REALLY need to find a Goldilock's zone within that Otherwise real science will be totally swallowed up by sensationalism and/or denialism Comment from : Tommy Vaske

Why do not make an instrument for radiation absorber and useful electrical energy that can be used for other purpose Comment from : Xehay Tecle

@40:15 The problem is in every collaborative I stepped into another job, with a company that feels like a startup, how the company have workers record their working hours by repeat typing each job they did out every month is just one of many issues bugging me, it's totally unproductive and old fashioned and insane by todays standards They were not taking advantage of data systems to do the work for collating data, and calculating hours As this problem was really bugging me, I knew there had to be a better way, I watched video after video on and learnt Excel, I also got some aid from Chat GPT too, to help with some of the formulas, but now I've built a spreadsheet that will save hours every month I knew there was a better way, it seems you have to stick with your idea, keep building on it and refine it, until you can demonstrate it to convince the, person(s) stuck doing something the past way Comment from : JoeySpeed

I am pleased to share with Lex, Tim, SpaceX, Nasa, Professionals and Companies the most advanced technological tool in existence: the Digital Twin that I invented in 1981 under the name of Virtual Instruments youtube/eadaQiL_AK0 youtube/fXlp4QLdWQs brExport the Copilot, Chat GPT, Revit, Plant 3D, Civil 3D, Inventor, Engi file of the Building or Refinery to Excel, prepare Budget 1 and export it to COBRA Prepare Budget 2 and export it to Microsoft Project Solve the problems of Overallocated Resources, Planning Problems, prepare the Budget 3 with which the construction of the Building or the Refinery is going to be quoted Comment from : Roldan Duarte Holguin

IT WAS A GREAT VIDEO,I ENJOYED IT AND LEARN FROM IT,JUST ONE THING: "THE ALLIES" WON IN THE "WORLD WAR TWO" AND BECAUSE "USA" INTERVENED IN THE WAR AND BECAUSE THE PRESIDENT FRANKLIN D ROOSELVELT DIDN'T WANT TO HET INTO WAR,"NAZIS" WERE WINNING THE WAR BUT WHEN "USA" GOT FINALLY INTO WAR,IT WAS A TURN OVER AND "THE ALLIES WON THE WAR"("USA" ENGLAND AND RUSIA)!!👍👍👍👍 Comment from : ISRAEL QUITO

This interview was NOT long ENOUGH! I NEED MORE!!! Comment from : morgan boyd

I’ve been waiting so long for someone who could explain all of this as well as Tim to come on the Lex podcast This is amazing Lex is such a great host and I love how he lets him explain everything and asks such great questions Comment from : Nathaniel Heustis

For long-term space travel, I would recruit sailors that lived on submarines We need a couple of pilots, but the rest could be engineers and techs that worked on subs Comment from : TexanUSMC8089

Bob Lazar is a story that's extremely hard to believe, but so far, I've only seen people come up with information that made his story harder to believe I haven't seen anything that proved he made it up If I can't prove it false, that doesn't mean it's true Conversely, if I can't prove it's true, that doesn't make it false Comment from : TexanUSMC8089

Throughout history, governments have caused war and division, not people The average person has no problem working together on a worthy goal Fortunately, governments change Leadership in Russia and Ukraine will change, and peace will happen again France, Spain, and England were at war with each other many times The USA has been at war with England, Germany, and Spain multiple times Right now, we're friends for the most part Space will bring about peace and joint activityif some power-hungry politician doesn't get involved Comment from : TexanUSMC8089

To put it crudely, we all die eventually I remember when the first shuttle exploded I would have volunteered for the very next flight I'm not a daredevil or adrenalin junky, but I have been a huge space fan forever I would love to go to space, even if it meant there was a chance of failure I would rather die on a rocket than die in a bed from cancer I would take Tim's place on this flight to the moon in a heartbeat Comment from : TexanUSMC8089

Since this video was released, Starship has reached about 130,000 feet The main thing that failed was the hydraulic system This was also the last booster with a hydraulic system The newer model has an all-electric system Hopefully, this will eliminate that problem, and the next launch will make orbit In my opinion, Starship is the next big step in rocket technology and will make all other rockets obsolete Comment from : TexanUSMC8089

A general IQ is less important than certain sections of the IQ test A person can have a 120 IQ but test in the top 1 for math or geometry Those people might excel in specific jobs like engineering but suck as an English lit teacher LOL I had an official IQ test It takes 4-6 hours, given by a psychologist, and has nothing to do with knowledge or education Memory is huge Comment from : TexanUSMC8089

Most of the time I agree with Tim, butwhen he said Musk buying Twitter wasn't that impactful, I disagree Elon saw that about 95 of the media in the USA was owned by 5 Corps He may have saw that as a problem and bought Twitter even though he didn't really want to get into social media He believes in freedom of speech for everyone Even if they say things you don't like In the long run, Elon Musk may have extended freedom in the USA Comment from : TexanUSMC8089

I support the Creative Society 👍 Comment from : Ярослав Калихевич

Rocket science is cool Comment from : TropicalOnion

they aren't landing the starship like a plane b/c they want to land it at the launch pad for quick turnarounds (future desired outcome) Comment from : Big Dog

I thought this video would be to long, But I love this conversation, listen to it twice now 10 hours 😮😅 ❤ Tim is a legend, start following his YouTube channel after this, Lex is my favourite YT channel, Tim's is now close second Comment from : 𝔻𝔸ℝ𝕋ℍ - 𝔻𝕌𝔹𝔼

I've never seen so many video overlays in a Fridman interview He really digs this stuff and it shows Comment from : eamonia

LEX FRIDMAN TALKING TO TIM DODD FOR FIVE HOURS ABOUT SPACE??! 🤔 I'M IN!!!!!!! Comment from : idle eric

I was always suspect of a channel that uses NASA in its name and is not affiliated This kid has no concept of science or engineering or materials…yikes…🙈 Comment from : We Tu Low

Lex, you improve my life Forever grateful Comment from : GE B

Thanks for this episode Tim knows his stuff, and expresses himself just like a "good" teacher One who inspires his students so that they want to know more, over and above what is in their textbooksbrWhen speaking about Elon, unfortunately, many people are just "rubbed the wrong way" by him Whether as the CEO of Tesla and SpaceX, or just due to his radical" ideas, there are a number of people who just don't like him, or his companies That said, in my opinion, Elon is a certified genius Just look at his wide range of interests, and expertise in so many different fields brAs Tim noted, when Elon couldn't buy a rocket for love or money, he read up and made his own Want an electric car, when no company is making one, read up, find some like-minded people, and make your own Finding out all the pitfalls found along the way, (which every new car company fell victim to), led him to start vertically integrating, so soon, except for the batteries, (which he is working on), they will make everything in-house except the tiresbrBuying Twitter should not have made Tesla stock go downhill, but, again, so many conflate Elon with the companies he runs He is one person and should be thought of as such That guy over there, he just bought something So what?brAs Tear-Down Titan Sandy Munro frequently says, "Don't bet against Elon, you'll lose" Comment from : Alan Rogers

Explain your shirt again please !wtf classic😅 Comment from : guess hoo

Get out the preparation H for that giant 😇 Comment from : Suta Laika B

Around 4:51:00, first child born extraterrestrial-wise, Mars birth certificate? Mars notary? Ssn, or maybe we'll see embassies that allow some of these things with med supply contracts until we reach a stamp act crisis issue past trade and currency decisions? Thoughts?

I’m ready to spend a couple months on the moon let’s get this going as long as Twitter is there but in reality, I am ready Comment from : George Henry

That took awhile but I finished it! Comment from : Darkcloudalpha

I started building rockets at 12 years old even put them on show in the seventh grade It was pretty cool I just wanted to go bigger and bigger, father and father Comment from : George Henry

Like NASCAR uses flaps to stop the car from rolling over or flaps even considered are they’re just too dangerous of falling off 2:08:46 Comment from : George Henry

Wouldn’t it be more beneficial to take off from mile high like Colorado instead of sea level? But it’s all about clavicle damage in the surrounding area, which makes sense, to bad Comment from : George Henry

What a great guy he seems to be fun to work with he’s definitely into the mechanics and other aspects to get you off the ground Comment from : George Henry

Seems to be critical to set up fuel stations above the Earth, so we wouldn’t need to spend so much fuel and power just to get there to the stations Comment from : George Henry

What is the consequences of one of the main thrusters not performing or actually failed? Can the mission continue? Comment from : George Henry

I’m glad to hear we’re talking about the moon because that is a good place to set up a station in practice for Mars Comment from : George Henry

I still think cybertruck is hideous Comment from : MC Hammer

i and a friend started a rocket club for boys in 1977 or so,, they created their rockets and we also fired them off at the local park it was a great learning experience for them Comment from : 0831sharon
