This man swooped up all of joe rogans fans that got left behind with topics like these. We love you for this Lex. 🙏🏽
Absolutely this. Joe Rogan content has changed so much from what I knew and loved. So grateful for Lex and his coverage science, space, AI and UFO’s.
I prefer Lex too, once Joe sold out it has never been the same
I don't have any issues with the Spotify platform, I prefer it for commutes and it's functionality has always been fine for me. Downloadable episodes so I don't need to waste data, can skip the ads...... I just miss the comments section, and I miss topics like this. We are all awaiting the jre episode on the new disclosures from dod and pentagon
@@stevencoardvenice apparently their numbers exploded so I think they are very happy. But I'm not sure if its only due to Rogan. It could also be because people are spending more time online during the pandemic.
@@stevencoardvenice if the deal didn't make sense to their bottom line, I am not sure they would have done it. Their share price jumped on the news of the deal, and it is still up above that level even after its recent drop in value from its highs. I doubt they would ever release the actual data but they have said that they got more traffic because of JRE than expected. I'm assuming some people are signing up as premium accounts as a result. I'll try and see if I can find anything concrete.
Each pen in his pocket is gifted by aliens from different planets.
this guy never runs out of pens
I have 1 pen and I've had it for at least 2 years🤣😜
You see all those pens in his pocket kids??.... Your looking at a Legend
Frank's point that the answer can't be more precise than the question went completely over Lex's head 😂
Lex-Highly intelligent Frank-Highly intelligent and lived longer....To your point Louis it did go over Lex head that the answer can't be more precise than the question.
The laughter you hear from lex is him thinking what a bullshit phrase that was said as if it's some universal law. The guy has obviously used the phrase before . You can come up with examples of why that type of thinking is ridiculous. What's 2 + x = 4? Not very precise....answer? 4. Precisely .
@@NoflectioN My assumption for Frank point is the if you give a broad or vague question than it has multiple answer which than can cause confused...But the process the question, and the understanding between both parties of the question being asked gives a prices answer or you could come to a conclusion that you don't have enough information to give an answer either which is an answer in itself.....
@@NoflectioN also your function understand of math or that subject matter alllows you to give that answer...But if your talking if subject you don't understand than you probably want to ask a precise or clear question to have an answer you can understand in your level
@@SkeemingforaBillion It's not a vague question. We *do* have a definition for "life."
If memory serves (from high school biology class):
- Can reproduce
- Can grow
- Is aware (can respond to its environment)
I forgot a couple, but it's not true that "we don't have a definition of life." The question is as precise as any other.
This man needs to see the problem solving ability of birds. I was absolutely stunned at their intellectual capacity.
Ravens can be scary smart
@@benparrish672 Exactly! I've seen them solve some completely new puzzles so quickly!
@@FuriousImp This is an added 60 million years of evolution to modern birds, so I suspect instinctively they're a bit smarter than dinosaurs 250 million years ago
@@jonathanbatista6135 From what I've understood from evolutionary biologists, high intelligence is a luxury. That's why it hasn't happened as frequently.
When you compare them to humans, its completely different. If humans go to another planet and find birds, no one would be as surprised as if they found other creatures similar to humans.
Only things to add in shirt pocket,
pen sized screwdriver for his glasses.
small slide rule , for sentimental reasons.
pen light.
Lex is cool , new favorite podcast.
the fear of not having a fucking clue kills them
2:30..."intelligence is kind of a luxury..." and harder to find around this days!
When I was 9 i would tell my friend's that there could be thousands of civilizations out there in space. Now I'm 56 and say millions. The universe is too big to comprehend.
It's 2021 and the government is admitting that UFO's exist.
We live in crazy times friend.
@@grindcoreninja6527 Do you think it's a smoke screen to hide new tech military aircraft?
@@humamumtaz2719 i think its unlikely to be a smokescreen to hide new tech. If anything this becoming public could increase other countries researching and spying into this matter.
@@humamumtaz2719 I thought that at first, but no, which makes me even more uncomfortable.
If it was our own technology it would be hidden safely away around groom lake, I also can't imagine it's a foreign weapon as we spend more on our military budget than our two "advasries" and allies combined.
I'm not saying it's alien's, but holy shit it could be.
Too many people (in my opinion) are approaching the question incorrectly-from a philosophical perspective.
There are 10^22 (or 23) stars in the known universe-and there are good reasons to believe the universe is vastly larger than what we can observe. That’s a 1 followed by 22/23 zero’s.
They say to themselves there could be millions of civilizations and many billions of exoplanets with primitive life (many will say far less) However, that would still make up an exceedingly small percentage of life harboring solar systems.
This conclusion is reached on a bad assumption in my opinion. And that is that life is a result of chance (accident ).
I believe life is not a result of chance, but an inevitable consequence of the governing rules/forces of nature.
I will provide you with a philosophical argument for why life exists in the vast majority of solar systems.
When we observe the known universe we see uniformity; it’s a real lot of the same things. The universe is governed by a specific set of rules/forces, which we can label natural laws. These natural laws govern matter/energy causing it to take on specific forms, e.g. quarks, protons, neutrons, elections, atoms, elements, molecules, amino acids, proteins, moons, planets, stars, galaxies, etc.
All of these systems of matter/energy do not emerge by chance (accident). Instead they are an inevitable consequence of the natural laws of the universe at work
Let’s take an atom, the building blocks of larger systems including life.
The strong force (or strong interaction) takes quarks, which are the smallest forms of matter we have observed and binds them together to form protons and neutrons. On a larger scale it takes these protons and neutrons, binding them to form the nucleus of atoms.
The electromagnetic force takes electrons and binds them in orbit around the nucleus and the result is an atom.
Two distinct forces are operating here together to produce a highly creative effect, the formation of atoms. Other forces/rules of natural laws then work upon atoms to form larger systems of matter.
Why then should we assume that life,-the most sophisticated system of matter-which is actually comprised of these smaller systems of matter I mentioned, a chance event (it happened accidentally).
As a matter of abductiive reasoning (inference to the best explanation) the best conclusion considering all of the current data is that life is also an inevitable consequence of the natural laws of the universe. And is part of and not distinct from the uniformly we observe all throughout the universe. As a result, life exists all throughout the universe as does all the other mentioned systems of matter.
Science is teaching us that rocky exoplanets around other stars exist in abudance. Mars is believed to have had a thicker atmosphere and rivers of water on its surface.
The evidence for my hypothesis is growing over time.
Car keys, check
Glasses, check
50 pens, check
Six pens.. six! Sorry.. the amount of pens in his shirt pocket was distracting me for the entire duration of the conversation..
Does he have 7 rulers in his pant pocket ?.
Is a "comb almost" an incomplete comb over ?.
"Big stomachs and small brains" he must know my wife.
William! You should be ashamed of yourself lol! 😂
Damn homie 😂😂😂
That's a good one reminds me of my first one LOL
What also scares me is that we might not comprehend other forms of life well enough yet, like there could be life forms in the Sun that we can’t comprehend yet, but they have been comprehending us and have been watching us this entire time...
Lifeforms in the Sun cannot comprehend us because they can't see anything.
anyone with that many writing utensils in his front pocket is for sure a go-to guy.
a few hundred years ago, his ancestors had big feathers...
James Bond Weapons!
Lex: may I borrow a pen?
"I have different opinion on different days of the week" this will be my new catchphrase.
Awesome stuff lex the way you use that out of focus mark at the end really made me think my eyes were going crazy
the parameters that human life needs to survive temperature wise has a fine margin. But other life forms can survive freezing and also high heat such as at the foot of thermal vents , so we should never limit the search just for human like life
I agree . Also think pressure is a big factor too for humans . I really believe intelligent creatures can exist under the craziest extremes .
Life can exist in the relatively small "habitable zone" portion of the galaxy. If life exist it would be inside the10,000 light year radius from earth. - could intelligent life evolve the same way in earth? - of the 50 billion species that had appeared on earth, only one specie - the homo sapiens rose with consciousness, to build his cities and his technology.
This is human ego, case and point. We always think we are the best and anything else must be like us.
@@lebowskiunderachiever3591 humans have been part of the universe on terms of this planet for only a blink of an eye, maybe there are other human like species out there but in a world where truth is often stranger than fiction I would say expect anything. Imagination and humbleness and forget the usual arrogance of man who seen to believe we are the only intellectual intelligent life in the cosmos.
Keep them coming Lex.
Para Adelante!!!
How many pens do you really need to carry around with you?
It depends. I think, once a advance thought appears, he quickly needs to form the words and colour in writing in order to fully understand the sweeping thought. That's wise thinking if it's the case.
Yes.
@@iced3263 you make a solid point
@@mdarey13 - a solid ball point
I'm crying! I love the pens 🖊 and the comments now I'll watch the video again to absord the knowledge.
I wonder if a hundred years ago his ancestors had big fancy quills on their lapels?
😂😂😭
Lex has begun to develop a level of clout that his scientists are nervous
There are billions of planets and billions of stars.
It seems very arrogant to believe we are the most intelligent.
Probably there is no life elsewhere in the universe let alone intelligent life
@James Buck It’s hard for people to come to terms with the fact that there is so much humanity doesn’t know.
Heck, just go back 100 years and look at what life looked like compared to life now. Think of the jumps that we will make in the next 100 years.
“There is no life elsewhere”
In the future this comment will be similar to when people thought the earth was flat and the center of the universe.
@James Buck looking at the problem backwards and assuming the universe wasn’t purposefully designed for life to emerge. For a self replicating unit to emerge from a system of rules depends on how conductive that system of rules is to producing such a unit.
I’d argue that the vast majority of rule system configurations will not be very conductive at all to producing a self replicating thing, however with enough time and space a self replicating unit will form somewhere in such a system so long as the odds are not zero.
It seems to me that if you are a sentient self replicating thing and 1) you identify only a single origin event behind you 2) the universe around you looks silent/empty 3) you are having trouble fathoming an easy abiogenesis pathway based on the rules of your system, that:
You are most likely in a case where what you know as life emerged as part of a very very very low probability event in a very very big amount of space and time and the next place it happened is so far away as to effectively be outside your visible universe.
Could be wrong but it’s an intuition.
Where's the proof that there are billions of planets and billions of stars? There is no proof...that's just something that you have been told.
To think that we are the most intelligent life would infer that there is other life in the universe.
Where's the proof of that? There is no proof. You can come up all the equations you want to...that's not one thread of proof.
What makes us so arrogant is the fact that we spend trillions of dollars on Space exploration while ignoring the problems we have on planet Earth.
What difference does it make what's out there? How's what's out there affecting anyone's life on Earth? It's simple it's not.
@@kennethcraig8410 lmao
Drakes Equation pops into mind
No way to tell how many civilizations are out there, I'm sure it's more than we imagined and more than we can deal with.
On the question why more advanced beings wouldn't invade us, I would postulate that since they are capable of covering the distance between stars, in doing so they are also breaching the boundaries of time. Perhaps as a species humans play a vital role in the timeline they come from and are therefore very selective with how they interact with us; so as not to disrupt the said timeline.
All I want for Christmas is to be able to xsplain stuff just like lex. How is he able to stay so calm whilst talking about th stuff he do! All I have to do is think about lookin up at the sky and I instantly frazzle min and Everyone around me within seconds
"Two possibilities exist: Either we are alone in the Universe or we are not. Both are equally terrifying."
Extremely interesting points raised by Lex and points relating to liquid crystals and cell membranes.
Our cell membranes are liquid Crystal's. Never looked at it that way before. Pretty amazing
If i was a betting man,i would bet that:
1)Life is ridiculously common in universe.
2)Intelligent life (self conscious) on the other hand would be ridiculously rare as brains/organs capable of necessary computing are a huge burden evolutionary wise.Even we went almost extincted numerous times.
3)Intelligent life that produces technology, would be even rarer. That might seem odd, but intelligence's leap to technology is HUGE and depended on so many factors. With the current data i believe that we are probably the only species capable of technology in our galaxy cluster.
Hey real Lex, there's a fake Lex lurking on your comments asking people to direct message him on whatsapp. I reported it just thought you should know. Fake Lex has same pic but mark above the "e" and a period after name.
Hello lex, what is the small cube that lights up when you talk?
TIME CRYSTALS !?
Great video thanks
Humans from the future, wormhole traveling squid, rock people from space.. "alien" is a very broad term.
In the North Vietnamese Army that many pens denotes a 5 star general.
If you think about it we have many different life forms already here on earth.
Who are you to decide an elephant is more important than an ant ?
the strange thing is that life only emerged on earth ONCE. They are like, its super easy - barely an inconvenience, happened as soon as Earth was formed. yet, it only occurred once. It seems reasonable there should be many lineages, many different types of like (such as silica, non dna, etc.), but there isn't.
I listened to this whole episode and it was fantastico, like all the rest of them.
The bottom line is we don't know. Other than on earth, life has not been found anywhere else in the solar system. Other solar systems are too far away to be thoroughly investigated, at least so far.
Until we set up the James Webb Space Telescope! :)
@@tinman652 An exoplanet atmosphere does not necessarily prove the existence of life.
Certainly not definitively, but detecting methane and nitrous oxide, or chloromethane gas would be very interesting potential biomarkers.
@@tinman652 I agree. I guess my broader point is that some people see a video and assume it is an alien spacecraft. Some people say that there are billions of planets, so aliens must live on some of them. But that is not really how scientific facts are proven.
@@deanalbertson7203 yeh. As far as we know and can to date assume we are alone in the universe until proven otherwise. It is interesting though that plant life can live inside spacecraft and Tardigrades, the Only Animal That Can Survive in Space.
Great video!
Fun fact, Wilczek in polish means "wolfie"
If anyone wants a deep dive into the fermi paradox. Look up isaac arthurs youtube channel. He goes into in depth more than any other youtuber.
However, once you watch it.. you will see comments on videos such as these as very ignorant of the insane amount of factors which can go into the fermi paradox.
Yes and no. You will have a better understanding but also if you truly understand and open your mind then you should let the ego go and realise we really don't know shit
@@sheshd have you watched any of isaacs videos on the fermi paradox?
@@mikeunleashed1 absolutely have. It's exactly as I've said. We don't know shit
@@sheshd then you should realise there is no ego going on here
@@mikeunleashed1 ohhh nah you mistake me. I'm not talking about your comments I'm talking about those who claim such possibilities are fake etc
Octillions and beyond. It doesn’t end.
The amount of colorful pen in his front pocket
““The Milky Way has 570 billion suns w/ planets, and about 7 million solar systems w/ planets on which higher life forms exist. In this galaxy, there are 2.63 million highly-developed human civilizations and another 1.141 trillion from other galaxies. There are about 1.04 million civilizations in The Milky Way that are developed only to a low form of evolution. Plejarens estimate that approx 6-7 trillion human civilizations exist in our space-time configuration in this universe.”’
-You’re Welcome
You know someone is a a true scientist when whats he is saying is barley catching up with what he is thinking or imagining. Great stuff out there!
"My feeling...." @3:44
enough said...
Lex needs to get Tommy Lee Jones on the podcast. He found intelligent life near the edge of the solar system.
Which movie was that? MIB?
@@TheJeremyKentBGross Ad Astra
@@iverstim He didn't find any, brother.. that was the entire point of the film
trade you a pen for this comb? 👀
Lex Friedman your awesome man keep up the good work I listen to everyone of your podcasts and I can’t get enough. A like would mean the world to me
I’ve just given you a like
@@bl1398 and I disliked
Latest estimates by astronomers: Water is a plentiful molecule in the galaxy & in the universe as a whole. So it's reasonable to assume that life as we know it is plentiful.
Lex "those are just words" Fridman
Yeah the pens are great, but this dialogue would have been much better structured around the great filter.
LEX is asking about alien civilizations other than his own native alien civilization
Great videos & I'm glad you are of a peaceful species
I love all the pens in his shirt pocket. This guy is real
Shabbat shalom and also Israel is forever 💖
The Local Galactic UNION of Star Systems consists of over 100,000 Star Systems that form the Orion Spur of the Cygnus Arm of Our Galaxy.
3:56 listen carefully
We can't even imagine
Another wonderful and thought provoking vid. Dude just needs to breath normally instead of gasping while talking. I've never he+ard someone talk like this before. It's almost as if he was so excited and liked talking so much that his brain told his body to stop breathing and focus on just talking and then once his "point" was made,j take a quick and loud gasp.
Warning!!! Alien civilizations hidden in plain sites disguised as pens
Brad Pitt should play this guy. He would have to carry multiple pens for 8 hrs a day to prepare for the role.
for me my life too much struggle lots of pain I suffer myself but never give up and keep going
This guy has many coloring books in his car.
Is it arrogant to say we are the ultimate intelligence? Our judgements as creatures seems to be quite limited. We run headlong to extinction.
Waiting for 1 of his pens to leak!! 😂
Is this that scientist from Half-Life?
That guy without hair would look like Jeff bezos
I wish I had just one more pen !
"in the spirit of being humble"... Lex always goes there. There is no rationale or logic that is improved or worsened by 'humility'.... The guy with the pens is plenty humble, he simply has a difference of opinion. He believes the requirements to achieve our level of intelligence or beyond is astronomically difficult to occur. Humility has nothing to do with it. Think of all the mass extinctions, perfectly timed, while orbiting a stable star, just the right distance away, had to happen so that primates could form... and then from those primates, intelligent humans.
My guess is as good as any Intel ectual because nobody knows and nobody is ever going to know so stop the guessing
Stretch out Danny DeVito and you get this guy.
For the millionth time , are there alien civilisations? For the millionth time , who knows !
Penmanship..........
Billions of civilizations out there
The conditions list of life, always excludes the most important and most elusive.
A robust magnetosphere.
That can be negated with a thicker atmosphere or shell worlds such as europa. Life can also evolve to live in radiated environments.
@@mikeunleashed1
Perhaps evolve to survive, but to begin in that environment? I don't think so. An atmosphere thick enough to protect itself from the solar winds, and charged particles would be so heavy it would be uninhabitable.
There could be billions but the universe is so vast I fear we are effectively alone.
Lex “I want to believe” Fridman
Aliens styled this guys hair.
What are Yoomans?
Many
I bet his pen is mightier than his sword.
What is life?
Baby don't kill me
Warriors wear their medals on their chest as signs of battle hardening heroics. This guy has a pocket protector with pens. He just needs white tape on the bridge of his glasses. Gotta love the evil genius laugh.
How many alien civilizations are out there? None. A humble opinion in the shadow of the "Fermi paradox".
You poor thing
@@girthbrooks6414 That's rich!
This dude screams mad scientist, just needs the pocket protector.
That is an unreasonable number of pens.
Yes, and a smart person would realize that the odds are in the pens' favor of one of them bursting and leaking all over his Tommy Hilfiger shirt. Ergo, get a protector.
Can a non social species develop an advanced world technology or are all technological worlds if they exist imply social beings.
Is that a comb over?
Love you dude
Instead of a luxury, intelligence might be a bad evolutionary strategy.
Yup. But successful so far
So this is the new JRE lol, im down
3:56 someone stomach is growling. Hear that fasting. 😁. Btw i agree with most of the comments, Lex way better than rogan.
NOT....."what is life?" the question should be: What is intelligence?
Over a million civilizations just in our galaxy. I'm sure many have just invited the wheel.
Dude looks like Jim Layhey from Trailer Park Boys
Is it at all possible that some day we discover these entities are dimensional and not from this universe. Just seems so unlikely that any life form could travel the distances required to make it to earth.
Distance is only relevant if you have a finite life span. If you are immortal then distances and travel time have little influence over you. It's likely any space traveling aliens have solved the aging problem. You would have life like VR for entertainment as you travel or just set yourself to coma with your smart watch and "skip" the travel time altogether. 1000 years at half light speed would feel like a nights rest. We just don't know what could be possible.
For all we know they can take wormholes right into our galaxy
And that's no joke folks.
