  • i love the lecture indeed.. not boring.. lol ofcourse, because i love it..

  • @megacaviagek No it's not... But then it took an arrow to the knee...

  • I used to know about the Arrow of Time, but then I took it i...

    ...Okay that joke is really lame.

  • how does it feel to waste you life on soon to be proven beliefs

  • At 0:30 You can hear him fart. =)

  • pshh this dude with the dumb ass questions at the end cracks me up.

  • The arrow of time is not absolute & there is a small amount of non-linearity in quantum mechanics. Retro-causation is not impossible, you can influence the past. You can also see the future before it happens. These phenomena have been recorded & documented. Go look it up.

  • Pro Tip: Watch the at 360p. Audio is drastically better in the 360p version than in the 480p version.

  • The Matter Universe began from negative 4D Minkowski continuum

    The formula of this negative space is T=- 273,16 = 0K

    The negative 4D is a flat Infinite Pseudo Euclidian space

    The 4D is Vacuum, Nothingness , Emptiness

    But the Emptiness isn’t emptiness

    In this Empty space virtual particles exist

    From these virtual particles stars were created

    These stars (3D) exist in infinite space

    All billions and billions stars and Galaxies exist in this infinite Pseudo Euclidian space T= 0K

  • So... if there are many Universes, what's inbetween them and what's 'holding' all these universes?

    For example, a House plant, in a room, in a House, in a Street, in a Town, in a country, on earth, in the galaxy, in the universe, in the...?

  • @TheMassAnnoyance : you're thinking in 3d terms. The additional multiverses imply additional dimensions to our know 3 spacial dimensions

  • "In our Galaxy, there are 100 Billion Stars. In the observable Universe, there are at least 100 Billion Galaxys, each with 100 Billion Stars."

    Makes our 80 Year lives seem pointless, really.

  • Good seminar but I disagree that the arrow of time is determined by entropy. Ultimately measured by perhaps, but you could reverse entropy in a sealed box would time go backwards in that box? The arrow of time seems to me like any other spacial dimension, he says that up is only up because we have a point of reference but in a 1 dimensional space the spacial arrow would be apperent.Time is 1 dimensional, and the idea of a negative spacial dimention does not seem to make sense.

  • The speaker is correct when he says that the lowest degree of entropy existed during the earliest time of the universe. However, he contradicts himself when he says that the stars, planets & galaxies were formed at a later time because that constitutes a greater degree of order & therefor, a decrease in entropy as time moved forward

    Entropy disallows Cosmological Evolution from ever occurring. Thus Abiogenesis, being dependent upon Cosmo Evo, couldn't have occurred either & Bio Evo didnt either

  • The reason why he says that they get stuck at the point of the Big Bang is because they refuse to recognize that is the point of creation. Einstein's math revealed that space/time is finite & must have a beginning. That caused Big Bang theory. However, space/time is the universe, & the universe is nature. Thus, logically, naturalistic causes cannot account for the Big Bang because an effect cannot be its own cause. Logic dictates that a supernatural cause must have produced the Big Bang effect

  • The speaker speculates that the Big Bang wasn't the beginning, but that something existed prior to the Big Bang. However, that merely adds an extension of time to the phenomena & its still necessary to explain its own beginning... resulting in the same scenario, once again

    Time/space didn't exist. Then, from one moment to the next, the universe was spoken into existence. It suddenly exploded onto the scene... hence, the "Big Bang". This is consistent with the 2nd principle of the Law of Thermo.

  • 1:04:08 He finally says what bothered me when he brought up the Boltzmann brain problem. For a signal, it's easy to describe a complex waveform with only a few parameters--if the waveform repeats forever. But it can take an infinite number of parameters to describe a single pulse while keeping everything else static. It may be "cheaper" to change a few parameters that cause galaxies to form around the whole universe, rather than one galaxy while everything else stays in equilibrium. Brains, too.

  • @CHRIS3BEVAN You realize he's saying this was a proposed idea that is known to be wrong, i hope....

  • @cloffff Yup.

  • He kinda talks like Michio Kaku, lol

  • 40:30 - wait long enough and you'll get an universe like ours.

    Wait long enough and a hundred monkeys with one typewriter will produce the complete works of Shakespear too.

  • @CHRIS3BEVAN ....true. That's no refutation.

  • @Raflegan - let me know when a hundred moneys have written the complete works of Shakespear - then I'll grant it is not refutation.

  • @CHRIS3BEVAN ....statistical likelihood makes it likely I'll have been dead, and you, many times over. The universe will have achieved a near zero thermal state, many times over, before it happens. Yet in an infinite amount of time, it must happen.

  • @Raflegan I love it when the scientific mind shows its madness.

    Fair play Raf... I find that very entertaining.

    God Bless You <3

  • @Raflegan The statistical likelikood is one huge fat zero.

    I guess this is where we differ... coz you look at reality as a finit thing where everything decays whereas I see reality (the true reality) is not what scientists think is reality.

    The true reality is finite where nothing decays.

    The latest results from Sweden are already starting to confire the big bang theory is complete bull. When will scientists realise they are trying to measure an illusion?

  • @CHRIS3BEVAN It's just following the second law of thermal dynamics, not anything to do with big bang or what-have-you.

  • @Raflegan - I take it you haven't heard of the latest that's coming out of Sweden (particle accelerator project).

    Oops...

    Better hold your breath on that one... lol

  • @CHRIS3BEVAN You mean CERN in Switzerland? I think that just had to do with Higgs-Boson, that doesn't really pose a refutation to much else AFAIK. Anyhow, I am not much of an empiricalist; because empiricialism is its own antecedent.

  • @Raflegan Yawn.

  • @CHRIS3BEVAN Monkeys don't live long enough to produce Shakespeare's works by chance, but they do reproduce and introduce changes into their species. Given enough time, combined with natural selection where intelligence increases survivability, one of the descendants of those monkeys might write the works of Shakespeare. It happened once already and took only a few million years, if you consider our last common ancestor with monkeys to be a monkey.

  • @HitfulVids

    {Given enough time, one of the descendants of those monkeys might write the works of Shakespeare. It happened once already and took only a few million years}

    This is circular, or "tautological" thought. You began by seeking to explain the postulation of evolutionary theory. Then you presented the assertion that evolution occurred, as evidence that supports the explanation of the postulation

  • @Chuichupachichi I wasn't arguing for evolution. I was using it as an example of a process by which monkeys could (indirectly) produce the works of Shakespeare in much less time than the age of the universe. Yes, the example presupposes that evolution by natural selection is valid.

  • @HitfulVids

    Appropriately enough, considering that Evolutionary theory was born of tautology

    "the individuals of a population that are the most fit (identified as those producing the most offspring) will produce the most offspring"

  • @Chuichupachichi Huh? That's not evolutionary theory. What source are you quoting?

  • @HitfulVids - and your evidence for this is?

    ...lacking any credibility - yawn.

  • @CHRIS3BEVAN Evidence: Monkeys only live for a few decades. The number of possible letter combinations the length of Shakespeare's works has an exponent in the millions. By "Borel's Law", It is so improbable for a monkey to type the text by chance within its lifetime that we can consider it impossible.

  • @HitfulVids You may have descended from a monkey - but I have not.

    Just to let you know about that particular (evolution) lie. It was cooked up by a person called Nimrod who was responsible for building the Tower of Babel.

    Ever seen the program 'Monkey' with the priest caled Tribitaka. This program was based on the ancient writings of the time China saw a man roaming claimed his very hairy friend was a monkey that was half evolved into a man.

    Looks like these facts will catch up some day.

  • Entropy is a point of view. where were the atoms of the egg before it was whole. Where where the atoms in the star before it became one. The only thing Entropy can really be tied with is expansion.

  • i love this video. and btw religion is retarded. enough said.

  • A pity that Google sold us out for CA$H. Lifes do fall onto you guys....

  • "What I'm gonna try to do is to connect things that happen in your everyday life" 2:35

    Why don't you just get back at connecting blocks in tetris. and the guy at the beginning introduces him like god is about to appear. he should marry him.

  • i know in whom i have believed...also, if gravity is the ashes of electricity & time is a function of the square root of negative infinity, then I have had too much time...Thanks for sharing the letter from young Wing, cool. ALSO--take your Baby Universe, here in ours (amongst particular "brains") and have it's TIME run backwards...not for eternity, just back to where it would "ensure" the meeting of all yall. P.S. Time is not straight line it is a 3Dwave contained within 3D "tube". 3D graphs

  • English is not my first language, but I am really keen on watching this programme; fortunately there is subtitle here so I can quite understand the contend. Thanz to Google:)

  • This presentation was from 2010, and it was hosted by, and, I'm assuming, funded by GOOGLE? Better quality can be found in a junior high classroom and, if it weren't for the qualified, distinguished speaker featured, it would not be worth anyone's TIME.

  • @zachflame123 Exactly! The qualified, distinguished speaker is the reason people spent their TIME listening. Sorry the chairs weren't comfy enough for you.

  • there is no such thing as time its just passage of eternity

  • @Singerjoy wow, i didn't know idiots like you watched videos like this. you clarified that you do not understand the definition of INFINITY - they never said the monkeys can write the entire works of shakespear within the lifetime of the universe, they said within infinity - which means forever. i once tried to explain this to an ex gf, took about 20 minutes and she still didn't believe it. used words like 'hypothetical construct' - so dont worry, your not the only person thats severely disabled

  • DId someone at Google just ask about 2012? Am I imagining things?

  • Time is Maya...an illusion.

  • think about this~if we could put information on a light beam and send it into space we could hook up all the info on that light beam to all the computers on earth and know the future einstein said that the faster you leave the earth the slower you live compared to people on earth so if we could read the light signals as it go,s away from earth we could hear the future over via" radio waves or computers think about this~we would hear the future as light go,s faster away from earth time is speedup

  • @55painterman no you would not!the information will still have to travel back to you and it will take time ,even with the speed of light!

  • @aqaehsan11 yes" I know this? but if we could do this for just one year? I mean send light out and wait just one yr, for it to come back to us? 18 yrs, will have past" and this is alot of time to see whats going to happen" I might be wrong about the physics of it and' or its probabley impossible? but if we could do this? it would be fasinating" but I doubt if this could really be done, its just a theory of mine...

  • to me? we could see the future just by building a computer where as if you send a light beam into space and if we can retrieve that first light somehow that we sent in space and the information on it then we could see the future if its true that einstein said if we left the earth at light speed? and came back yrs, would of past on earth where as minutes would of past for the light think about this~the light will have the info from the future when we look at the info it collected when it left !!

  • ~all I know is? if this happened once~ it will happen again and agan and forever! space is infinate in every direction! inwards and outwards space is so infinate? that this big bang? was as a firefly in the middle of noplace, and in fact? space is so infinate that everywhere there are big bangs going off constantly" and have been doing so forever! no begining> no ending" space is a non stopping life mechanism of nature that makes life that is created and die out non stop" forever! and forever!!

  • @55painterman Too bad for me. I tried to read through your comments but you have such a lousy bad habit of not using punctuation, or maybe don't know how, that it's pretty much too hard to understand what you've written. Nothing is in complete thoughts or sentences. Too hard to know where to start or stop. Half quotes, question marks where there isn't even a question. Punctuation is really important - makes something readable or not.

  • @MrDBarch thats only because what I,m writing? doesn,t make sense either"...:}..plus I,m only 5 yrs, old...

  • "Time is really a big ball of wibbily-wobbily, timey-wimey ... stuff!" - The Doctor

  • You know, its okay to me that the majority of people like to watch other vids on youtube (cuz I've seen my share). I just like knowing I'm part of an elite, intellectual group that watches and enjoys these kinda vids :)

  • I wonder what the universes where you can remember tomorrow are like? Anyone have any thoughts on that?

  • @Sicknessdoa I think he answered that , anyway what you talk about is fantasy and the only ones that has this are people like Nostradamus

  • His idea of time and space is a good one. Expansion of a baby universe creates heat in the millions of degrees? And the part about monkeys typing for infinity will some how get one of them to type a book just doesn't seem logical.

    I wonder how the first atoms and quarks came to be?

  • History vs Science= NOT COMPARABLE

  • Google. Googol.

    There's a diff.

  • im the 33,000th viewer :)

  • So what happens when the expansion rate reaches the speed of light?

    Can this cause dark matter to start fluctuating in strength perhaps?

  • @HerrKnitler The Expansion Rate is already faster than the speed of light! Cutting edge physics can really mess with your head if you let it in too much :p

  • @Relbl

    No, the Expansion Rate is not faster than the speed of light. It's actually not even close.

    However, the more space there is between two galaxies/clusters, the more expansion of space there is between them, so the faster one recedes from the other.  So for very distant galaxies, their recession speed approaches that of light, and those that a far enough away recede superluminally.

  • So basically this is the excuse I need to not clean my room. Who am I to argue with the universe :)

  • Sean jokes that his photo of the Big Bang is a false color image. But interestingly, the earliest view that we really have of the Universe, the Cosmic Background Radiation, as "photographed" by COBE, WMAP, and Planck, while in the microwave range today, originally had blackbody temperature of 3000k, before being red-shifted by its long jouney through space. Which is almost exactly the spectrum of your average 100 watt light bulb.

  • Interesting.. I feel we are all underground like in an ant farm. Earth is just a spotlight selected within a broader uncultivated area. Big Bang exist underground only. Then the water seeps in to begin creation. the sun is round because it is seen by us through a peep-hole that size.. so it is actually alot bigger than the circle we see thru underground, it has no shape like pure fire.

  • I found this video amazing. Every time i tidy my bedroom and observe it getting progressively messier, i am really observing the progression of the universe to a higher entropy state...

  • @John2Thornton that's brilliant, that's why the big bang doesn't work because it goes from order to chaos not chaos to order

  • the pinched off energy looks like graphics ive seen of back holes. is this the "we live in a black hole" theory?

  • Hmmm. So how does he propose all this vacuum energy gets concentrated in one pinched off spot? Isn't vacuum energy uniform by nature? I've heard of measurements of vacuum energy -- never heard of vast differences in measured value though...

  • okay im going to reveal how stupid I am. I have absolutely no knowledge of physics whatsoever. I watched some other Cambridge lecture where this other physicist dude was trying to say biology is a fundamental force in physics rather than something that sits on top of classical physics. If biology is a self organizing force, is it possible its just a form of energy tranfer or is it new energy leaking into the system from adjacent universes? perhaps both?

  • @ginsushark

    Fellow idiot here =)

    I don't see the connection between life and other universes. I think it can be explained like you said that we are ultimately a system that can transfer energy to ourselves, actively.

    And yes, biology is ultimately an extension of chemistry which is an extension of the laws of physics. It's all just the human mind that needs to compartmentalise stuff. It'd be pretty hard to learn anything at all if the starting point isn't well defined.

  • @HerrKnitler - ultimately your starting point logic doesnt seem well compartmentalized.  but thanks for taking a stab at my random jibberish. i caught some other lecture series on the historic interplay of religion and science and figred out that the cambridge physicist dude was trying to find a sneaky way to bring creationism or some other intelligent design type theories into the mix.

  • Excellent talk. Loved it.

  • This was excellent. Superb. Thanks.

  • If a yak craps on an airport runway, it falls to the ground as it would in a strawberry patch. Gravity RULES because God made it that way.

  • I'm a nobody, but I just want to say that time is not there because of entropy but time is there because of the existence of irreversibility. The only way to stop time is to prepare for a total reversible state. And going back in time is impossible. If we went beyond the speed of light, then we would've gone faster than our brain electric signals but it doesn't mean that we would go back in time, this is just me.

  • @Melki

    As far as I'm aware, there is no law in physics that says that time can't go backwards. So in all technicality time CAN reverse, maybe loop. That irreversibility you talk of does not actually exist. Just random chance would say to only few molecules of the egg "you can form your pre-cooked state." Given enough times and enough eggs, it IS possible to say that only a few times out of, say, a trillion, the egg will revert.

    This may not be completely accurate, ...cont...

  • @TheCopaceticMan just consider this, if time would go backwards then the going backwards would took place after the current, that's not going back in time but going to the future. In the case of this video there was no guarantee that going towards lower entropies would always took the same path. I still think that physician's entropies are not the real disorder nor the determinants of time but merely some unidentified raw materials. By def, entropies = disorder, our inability to classify.

  • @Melki

    Yah, I posted those comment before I watched the video (wouldn't load so I just read few comments, the refreshed). Frankly, if what this guy says is true, (if I understand it) then what I say does have 'SOME' validity, but would take far more time to occur than the universe is around (it relates to the random motion of the atoms of a gas).

  • @Melki

    but I did get this exact idea from Michio Kaku. The whole random chance thing may not be accurate, it was the best way I could explain it.

    P.s.

    According to the laws of special relativity, if an object travels faster than the speed of light, the laws break down. 1/0 has never been calculated, and that is what happens when you travel at the speed of light. Talking about faster than the speed of light becomes meaningless. (You'd also have the same effect happening with distance, mass, etc)

  • So S equals k log omega is not always the case? I'm a christian and this doesn't shook my faith at all.

  • @Melki I mean delta S => 0 is not always the case not S equals k log omega. sorry

  • Its it rather prpbable every soul exist in bolsmanbrain in its own universe but still conected to the main universe to get the illusion of everythings real due to interaction ?

  • @Qulopuaa The only souls i know of are on the bottoms of shoes haha

  • Comment removed

  • why was there a vid of some guying eating and drinking in the backround? and wtf is wrong with 1/3rd of google employees?

  • So black holes give birth 2 other universes and then disappear?? could that be possible?

  • i say there is no such thing as the arrow of time. we experience time different from person to person. one person can do the same work in one hour when the other person use two hours to do the same work. thats because for one person the signals in his brain is going really fast and for the other person the signals are going alot slower, but both of them have experienced one hour. we made the minutes and hours, and not the universe. nothing goes faster than the speed of thought.

  • @coldarc

    the signals are all going by roughly the same speed. Whether or not these forms neural patterns that are useful from a pratical perscpetive of fx work and perception of time is of course varying from person to person, situation and time, and that people biological clock vary too so that they experience an hour differently, is true too. You got that right. But that doesn't really have much to do

    with the arrow of time, and thus you're probably still wrong..

    Try watching the start again

  • great talk Sean, i was wondering if you could highlight the difference between your scenario and Roger Penrose Conformal Cyclical Cosmology.

  • I do feel compelled to comment because I have my own theories which I think fit and are indeed within the realm of explanation. Ill note two, 1) Time is actually Gravity, because they are directly dependent upon each other ex. when speed is infinite, gravity is also infinite, but time stops. 2) I have a video on my YouTube account showing how I believe the universe came into existence, kind of like 2 groups of dimensions meeting, while keeping a point of creation as it's origin, have a look!

  • @heavensrevenge Saw your video, and though I do find it interesting, you need the math to back it up ;)

    It does not seem to be at odds with the Big Bang theory either, which is just expansion of space itself. It actually seems to fit in with it.

    Anyways, I liked your video.

  • pretty fucking absurd that im even typing this..

  • I love this

    

  • Seems like Google can't afford a HD camera.

  • the great thing is it's much more difficult but somehow we understand it :)

  • @DRG575 drago???

  • @DRG575 I agree totaly

  • i never liked the forever expanding universe idea but i guess if it makes a lot of baby universes its not so bad

  • Its always a little disappointing to me that TechTalk videos tend to have a few thousand views, but skate boarding dogs get millions. Just a random observation.

  • @srushaggs I think exactly that every time I watch any of this kind of lectures. But, people always watch only videos that they have any interest. And if you dont have any interest in this kinda stuff, this is boring as hell.

  • @srushaggs

    Not really, there is only a small number that can or are able to drive the future. And among those who have the raw potential, there are so many different potential directions that you would expect them to be spread pretty thin.

  • @srushaggs indeed, reflects the population in general sadly :/

  • @srushaggs : "Just a random observation."

    More than that, it's an impending disaster in a world which insists upon democracy. An unenlightened democracy is far worse than even a moderately enlightened dictatorship.

  • @srushaggs "Just a random observation"

    You are absolutely right. People are more interested in fun than knowledge. We have not developed taste of knowledge. Those who develop this taste they can not live without learning and discovering something new everyday... We need a department which would be responsible to keep feeding rebellious thoughts of existing things..Keep them disturb from what is available. Make them motivate to create which is better... Only then we can get more hits here :)

  • @srushaggs I recently came across this very funny video of the 2007 Miss South Carolina. She had difficulty time answering why so many American can't locate the U.S on the world map. As you said, just a random observation!

  • @srushaggs - It's a repetitive phenomenon unfortunately. Tell people there's a soccer game on this weekend and you'll get 1000's of people attending. Tell them there's a working bee for an underprivileged community and tumbleweeds are seen floating by that day. Horse race meeting vs litter clean up day, same result. It's been like that for centuries ie. Roman Colosseum days. People are more often enticed by depravity, carnage, violence, etc, than wanting to better another's life or their own.

  • @srushaggs its cuz dogs are in ya face

  • @srushaggs The dumb folks don't care, and the smart folks get their info elsewhere.  That leaves the dumb folks who aspire to be smart, watch shows like this, and try to act all superior to the skate-boarding dog-watchers. There are a few thousand of them.

  • @cosmicharlie1970 then you must be the dumbest!

  • @srushaggs whats that say about the average intelligence of the population?

  • @srushaggs Kind of like how more Americans are concerned about who wins American Idol, than who gets elected to public office. The elite and their MSM mouthpiece like it this way, too. Keep the masses interested in mindless garbage of no particular importance, and ignorant of the things that actually affect their lives, and they will be easy to control.

  • @dslgunner1977 as i watch my step sister eat nothing but steamed dim sims..(too lose weight)

    and idolized the models we see on TV...

    i have to say you are dead right....

    some peoples ignorance is so depressing...

    our race is screwed...

    Idiocracy has already begun!

    peace

    -Peely

  • @srushaggs i guess we as country (U.S) are not on this intellectual level yet and it seems like it's more popular in russia than the U.S but at least it's more popular in the U.S than australia and canada

  • @srushaggs heres a couple other observations. I can come to a party and talk with no more than one person about something besides gossip, drinking, partying and unintelligent topics. The one person I do sit down with and discuss space and time with has a passion for it. Even more interesting is that even when talking with him/her about this people will walk by informing us that "no one cares"...even though were both discussing it. Intelligence is looked down upon and its now cool to be stupid :(

  • Love the Sean Carroll. There are physicists who disagree with him strenuously about his many-worlds theory -- I'm not qualified to have an opinion -- but he's a terrific speaker and wonderful at explaining things. We're lucky to have him.

  • Really interesting.

  • i didn't like that way of showing the video the man in a very small at the top corner they could have made it in a different way like showing the man then when he brings an image they show the image instead of him for a minute then remove it and so on!

  • thanks God universe expanding , i like to have a lot space of living

  • Very very good!

    clearly explained, even to non-physicists, a very abstract and complex cosmological theory

  • An universe with Sarah Palin being a president is a very nasty one...

  • I need to find the universal chicken!

  • i like the experiment where they make people play video games were the controller works a second before the game. after they synced the controller with the game the subjects said they felt like they were ahead of time.

    something like that. Rob from the "10thdim" channel speaks of it.

  • If one uses fractal patterns as placeholders one can achieve the answers to the questions you are asking. Make your placeholders dynamic, not static. the universe isnt static. its a simple conversion, its the same math but its in motion and you will get more answers than you had questions for.

  • If entropy raises because there is higher chances for it to raise, doesn't it mean it can't go down sometimes for a little while (like for example making ourselves). According to QM it should be possible just unlikely, maybe big bangs are just things that happen from time to time, or maybe, just maybe, this weed was way too good.

  • @rata0071 hmmm maybe i should've waited, i always ruin the movies too

  • @rata0071 Lol! I see what you mean.

  • @rata0071 you are on to something cause i totally get what you are saying however I think my weed is great tonight so im not sure ill understand it later.

  • Thanks for this talk. Very interesting.

  • Thumbs up for cosmological chicken!

  • "The fact that we are first born..." - That's definitely a funny sentence when you've read the Time Odyssey trilogy by Clarke and Baxter

  • "Things don't completely rearrange themselves from moment to moment" - I reject this statement based on empirical observations of my closet.

  • lots of assumptions...

  • Why does he insists that we are not disembodied brains when it is more probable situation (52:30)? Can anyone help me out?

  • @jonask9 Ok, I got my answer at 1:03:16. Someone at Google had the same doubt.

  • @jonask9 - He explains it's pointless to asume it, even if there is the possibility. Also, he explains that it's more probable to create a baby universe in which, at relative low entropy you and your brain exists than have a single, high entropy universe where you are just a disembodied brain for a few seconds. So, from a multiverse point of view, it's more likely you're not a disembodied brain.

  • I read the book a while ago. Unfortunately, I was completely bored by the book and this talk. I'm just too educated about thermo to begin with to find much novel about his material, which is mostly basic physics prerequisites.

    His only distinguishing claim is the gas model that collapses to a low entropy point making a double arrow of time. Unfortunately, requiring an infinite amount of time fails the basic existentialist usefulness. If all possible universes exist then we exist, QED.

  • really interesting and well explained, thanks !

  • Really good talk, wish i could have been there, i would have had a few questions to ask myself.

  • So the entropy at the big bang was lowest then ever?!?! Little particles running around is lower entropy than galaxies with stars and planets and life. hm... again ... hm

  • @iTravelHD "So the entropy at the big bang was lowest then ever?!?"

    Entropy is a decrease in chaos. It can also be thought of as order, or even information increase.

    Mostly, it's used to denote stagnation. And certainly, the Big Bang was the opposite of stagnant.

  • There's an annoying high frequency buzz when played at 480p. I recommend going down to 360p.

  • @BigYellowKY I can barely hear that anymore, don't worry just give it four more years.

  • @BigYellowKY  Thanks
