- Опубликовано: 22 апр 2012
- www.ted.com At the heart of modern cosmology is a mystery: Why does our universe appear so exquisitely tuned to create the conditions necessary for life? In this tour de force tour of some of science's biggest new discoveries, Brian Greene shows how the mind-boggling idea of a multiverse may hold the answer to the riddle.

The more you know, the more you know you don't know.

kand m16 he got it from socrates i bet.. the infamous “scio me nihil scire”
lol
Yes
I feel like everything we think we know is as far away from what really is as possible, and what actually is, is far more complicated than we can even comprehend, even on the most fundamental levels. We may never come to understand existence because existence was never meant to be understood.
@current_interest I love Quantum Mechanics because it put contemporary physics on its ear. So much for (one era) of scientific knowledge explaining everything.
Brian Greene is indeed one of the greatest scientific speakers.
Wheter you like his ideas or not, you have to admit, he's good at presenting them!
overTIMe He failed to note a minor detail.
The multiverse doesn't evade the strong evidence for design, it actually compounds it.
Design is even more implied by a multiverse than a universe.
There is no way out for atheists. The way is shut. Come back to the light.
jonesgerard *Design is even more implied by a multiverse than a universe.*
This would only make sense if every universe within the multiverse was complete and fully formed. Smolin's 'Daughter Universe' theory, although not testable, still uses the same framework of basic evolutionary theory and proposes that the many variables that make up a potentially stable universe are not often/rarely met, leading to catastrophic collapse of the vast, vast majority of other universes. The ones that are left over, that are stable, are merely a product of insanely large number survival theory.
If, however, we found good evidence that ALL universes within the multiverse NEVER collapsed then I think this could be a solid foundation upon which to hang a possible theistic hat. I think we're a long way off from assessing any of these claims so what's the most honest position to take? I don't know? OR, I know, I believe based upon a really terrible bias and globally recognized ineptitude by people to misconstrue and misunderstand anything to do with probability and large numbers that a god(s) exists? Anyone who has ever taken a probability or statistics course(s) understands just how natively crap we are at these things.
jonesgerard So what designed the designer? And what designed the disigner of the designer?
+overTIMe Indeed, he is one of my favorite speakers.
+overTIMe I felt the same way, he sure is a great speaker. My only concern is the content of this speech.
There were a huge gap in his argument, when he connected that infinitesimal small number to the fingerprint of our Universe. How exactly did he connect those dots?
That was just a speculation on which he didn't spend much time, and that was the core of his talk.
I agree that we're in an exceptional position, starting from the conditions of our planet, to the very laws of physics that support our existence. And it's very likely that there are other universes with different laws of physics that would evolve differently. And this miracle is worthy of extensive investigation. But taking that huge leap of faith, just so we can say that we understand our world is not scientific.
I admire how Brian Greene is so absorbed in his explanation. It is like an adult telling children's stories to small children. :-)
he is a well paid actor
Yeeeees!!!
It’s almost exactly what it is since what he’s talking about is basically philosophy and imaginary, not real life. He’s not doing physics anymore.
@@JPoleet you have to admire his intellect and how the way he do lecture
@@alpacino4857 Indeed he is extremely intelligent and I would be stupid to pretend otherwise, I just think he is a peddler of pop culture science, a woo spreader not quite to the degree as What the Bleep Do We Know, but still.
I feel so good reading this comment section😭
Some of my friends told me that I'm mad because I am interested in stuff which is not related to my engineering branch
Dear, we're not robot, but we live life from different perspectives:
1. Humans made this SOCIETY through thousands of years of learning and everyone in it lives as per norms(social, economical, etc.)
2. Some try to understand the BEGINNING and END, how things works, where it is going
Live your life on your terms what makes sense to you. Enjoy your time. Don't exaggerate, if life is true so death.
Me too brother
It's ok to be mad. I have interests in music, dance, nutrition, health, chronic diseases, healthy aging, consciousness, cosmology, quantum whatever ... I half understand but so what. You are just more curious and multi-faceted. Celebrate your madness :D
Dear bro I'm also an engineering student but I love lots of things like science,philosophy and mysticism etc things and its normal it's nature of human beings they love to explore and that's not madness that's something Good
@@younaughtynaughtyboy9980 me too brother, me too.it certainly seems very strange that most of the people don't have interest in science and cosmology.I MEAN THAT IS LIFE THAT IS EVERYTHING
Love his PRECISE AND CORRECT wording: ""our form of life"" , as opposed to just saying "life".
Many forms of lies.
Don't you know it?
@@arreff2012 how so
Me too. Life in its current form literally only exists due to our current climate and environment. If the earth changed dramatically again then some life would die off and new forms of life would evolve to adapt to that new world. It was mind blowing for me to realise this after years of being brainwashed into being told evolution was a lie and life was specifically created as it is now.
@@adrianneavenicci , Micro evolution can be proven and shown by science, Macro evolution is just a theory. Until science finds real evidence that one kind (species) can evolve into another kind (species) I will be very skeptical of it. I always keep an open mind, but if they haven't found anything yet, they probably won't. DNA needs a cell, a cell needs DNA/code, information to know what to do, what to become, and how to form. The question is, who or what designer, programer created the DNA code/information?
@@adrianneavenicci .. wait! You carefully avoided explaining what 'new forms of life would evolve to adapt to that new world' - there's a different process when something adapts and adaptation is not 'evolution' in the sense that different kinds (species) are generated. Even current real world observation does not show that adaptation produces anything new > no new genetic code. Environment does not change the DNA sequence for offspring. Kinds remain kinds - birds remain as birds - cats remain cats, dogs remain dogs etc. > can be proved that all species have genetic boundaries. Modern scientific research proves Darwin was wrong.
This guy is a great teacher. I actually understood everything he said, even the little details. That is a gift, not many can pull that off with these kind of topics.
i like his clarity acsent and he seems cool - hes good on giddence but on universe knowledge soon will gange soon all we all be joing a better idea we all need of madonas people,gravity and electromagnetism all seperated will not make it any sistem that you tell me of
I love the topic and also think he's a great speaker. And, yes, he has a gift for putting things in simple terms (something that only people who truly understand the subject material are able to do). That said, there were still several things he said that I didn't understand.
@@responsibleparty keep in mind that understanding, and agreeing are different things, you can understand something without having to necessarily agree with it, maybe that's what you are referring to.
if anyone understood this subject completely they would simultaneously be able to fill all the gaps in quantum mechanics and there'd be the 'theory for everything'. Physics would be solved.
@@espaciohexadimencionalsern3668 I don't recall any specific stuff he's said, but the above paragraph just leaves me with about 95% confusion. (I understand up to "... seems cool ..." - what does "… on universe knowledge soon will gange (change, I'm guessing) …" mean? Our knowledge of many many things has changed and grown virtually exponentially after ~1900.
Then, what does "… we all be joing a better idea we all need of madonas people …" mean? It seems completely senseless, unless you think Madonna's fans are going to save the world for some reason?
Finally, what does "… gravity and electromagnetism all seperated will not make it any sistem that you tell me of …" mean? Did I miss something about him theorize separating gravity and electromagnetism to make some system? Regardless, gravity and electromagnetism are already "separated" as much as any other forces of nature are (strong and weak nuclear forces, even electrons self repelling (whatever that's called, maybe one of the two nuclear ones above?), plus the 2 you mentioned. They're separated, but still all part of the same system (our universe) just as the parts of the engine of a car (like that new "1") are separate, but must work together, or it all fails.
"sometimes nature guards her secrets through with the unbreakable grip of physical law.Sometimes the true nature of reality beckons from just beyond the horizon"
Brian Greene has so much passion, we as viewers are lucky to have him... His specialty is making it exciting and accessible for regular,ordinary people. I remember watching “ the Elegant Universe “ when i was a kid,and being extremely inspired. Its amazing the stuff he (and others)predicted so long ago, is finally coming into light.
What happened to him?

@@Boogieplex *"What? Salesmen dont make information exciting and accessible for normal people…lol."*
... No, salespeople make their product "exciting and accessible" so that people will want it and buy into it. Greene is a salesman selling you a product: String Theory. All of his exciting graphics, personal energy, and witty prose are part of his salesmanship.

He admits all the time string thoery could be wrong. He simply states facts,and his opinion when asked or needed. If you want to dispute ONE SINGLE thing he’s stated that you find untrue, im listening..Im gonna take a guess that the probability of you being a fan of E.Weinstein is extremely high…lol.😂😂😂
Whoa, I actually never thought about how astronomers in the distant future won’t be able to observe the universe as it is today because of the expansion superseding the speed at which light reaches us. They will see less than we can and they won’t believe a word of our “ancient research”. That’s actually a frightening thought.
Dionisio Those scientist would most definitely know about that and immeadietly understand that the universe looks different to them if not our civilization died today, like Rome to us and some science was forgottrn about. They would still learn it eventually.
I guess you mean that they won’t be able to see as far in the past as a lot of things we see in the universe actually existed many years ago.
He is talking about billions of years. Humans will not exist. This man is preaching to the ignoriant current populas.
@@petergreen4213 why wouldn't we exist?
Well, two possibilities. Neither outcomes warrant any worries. We either went extinct because we are too stupid or get eliminated by aliens, or we live long enough with technology travelling between Universes or dimensions or even be able to slow or stop the Universe from keep expanding.
@@faustacastaneda1578 "why wouldn't we exist?"
In billions of years time, we will have evolved so many times, it'll be Humans 97.0 which will be the dominant species. We'll probably have been driven extinct by Humans 2.0 or 3.0, just like our 10+ previous hominid species are now all extinct.
'I think nature's imagination Is so much greater than man's, she's never going to let us relax' - Richard Feynman
hahaha pleasantly laughing ... natures edge is us so far ... well some of us :)
Nature's imagination,..hmm. Even the atheists can't stop personifying the cosmos. Maybe we are designed for worship.
Humans are personifying the reasons of the processes they cant understand. When thunder struck 1000 years ago, there was an angry Thor/Zeus/(some other good) hurling lightning bolts, and that was a serious explanation.
Humans can personify processes they DO understand:
"She sits above the circle of the sun
Its inhabitants dwell like creatures around a thermal vent
Neither too hot nor too cold
For She wraps her Zone around them like a dwelling place."
[Isayer40v22]
If a love of poetry can be construed as "worship" then all hale to Goldilocks! lol
Mans imagination is much greater because he does his very best to ESCAPE from the Truth of God the Creator with tons of lies and evolution dogma,when he never will be able to. The very "dark energy" that we do NOT see that holds the universe together is the Power and Word of God! Put that in your computation and see what you imagine then?LOL
That part about future humans observing deep space and seeing nothing but darkness really hit home for me
Great job Dr. Greene! I am pleased of the current understanding of this great mystery.
I am both ASTONISHED and SCARED by the capacity of reality.
tosome is not but a cuestion of believing.
they got you now. open your sences and feel it in better way
Reality has no capacity.
@Ronnie McColl d DNA IS MUCH like the sun or a galaxie, DNA interacts cross section from south to north and viseverse exchaging information, the relate to color this are red, yellow, blue and white and the farthest red star of south side relates to the farthest red star of south side and all stars are related the same by color respectibly - take a look to ALTON HARP INTRINSIC RED SHIEFT in here he says that the visible universe counts with 7 steps that are all the colors of a raibow so our system or our universe is a brocken system, wene systems are not brocken there are only 4 colors as I told you - thanx for answearing any way - we may go paralel but stell we are in the same rute.

Out of all the ted talks I have watched till date.. This one deserved a standing ovation the most... :/
This is a brilliant explanation 🙏🏾
This man does an excellent science concert!
I love his energy and dedication to forever learning!
Brian Greene, "the elegant communicator", makes cutting-edge physics understandable even to math dropouts like me.
Yeah. How space is created is unknown. Well we also don't how anything at all is created. So space is constantly being made and the matter the universe is still the same amount from Big Bang. So is it logical to say that the vacuum in newly empty space is sucking at galaxy faster and faster as newer and more empty space is made? Just a thought of none science guy.
Amen!😀
This is the typical disservice that materialistic scientism does to science.
First, to establish that there are innumerable universes - perhaps infinite - with different physical constants, a fundamental point comes in: why in none of these universes is its expansion so accelerated that it would eventually collide with other universes and thus create a cascade effect so that nothing eventually balanced how our universe could exist?
Secondly, how to explain what is this network that holds infinite universes, because a universe generator is something very well adjusted and with completely specific multiversal constants.
Thirdly, no one answered why we are here. Even the multiverse being a truth.
Brian Greene the guy who dumbs science down enough for regular people to think they actually understand it.
@Raw Engineer Could easly be. His head is full of strange fantasies.
I loved the amount of energy he put into this talk. Made the world of difference 😉 my favorite ted talk to date
Brilliant speaker, just sooo captivating. I watch this video every two weeks or so, I feel so energized after watching it
the way he explains his ideas and explode like a supernova is simply stunning.
Love the conclusion wrap up parts. Phenonmental presentation.
best speaker hands down. Just watched his string theory video, best explanation ive ever heard
Coronavirus doesn’t matter is what I’ve learned after watching this
What u mean?
no, comparing with the future, now is more important
Qiaosong Deng nothing is important. You have a false sense of importance.
So, who's ready for pizza?
@@alexo277 hundreds of thousands of people are dead across the world.
The universe is big but we are still human and we are still small. It may not be important to the universe but it is important to us. What is the point of all this 'enlightenment' if you as a human cannot recognize the weight of human suffering and pain? He doesn't have a false sense of importance, you have a false sense of enlightenment.
This talk made me anxious.
Many thanks to ELENA Montasio for her translations. I can finally follow is to understand the various characters that from the TED stage explain their life experiences, scientific research, art and many other topics that are very instructive is also socially useful for many people. This lesson in cosmology and astronomy struck me as much as it is the subject that fascinates me the most. I believe in the theory of many other universes. It was a wonderful lesson. A cosmic hug at TED.🙏👏👏👏👏👏👏❤️
Thank you Brian Greene, you are a wonderful science communicator.
What a talk. Spectacularly mind-blowing!
May be somebody is watching us who are in a packet of multiverse through a large microscope. Saying “How dumb these microbes are..."
In case they are watching, when you go outside, be sure to give them the one-finger salute.
and they might just comment on how clever those microbes are.....
Lol, I like that one! Could be true!
ZaphodBeeb1 haha! But if we piss them off they might spray some disinfectant on us
@Emilio Ortiz. Ah yes ! But through natural selection we would evolve into super bugs which have a built in resistance to their disinfectants. Then we show them TWO fingers.
I'm not a science person but in fact I fell in love with just the introduction and I understood everything Brian said. Thanks so much Brian.
So you understand the multiverse that has zero proof and defies all physics. Great, tell us how it all started with creation happening naturally with science. In other words, give me a good laugh.
2fast2block what are you even saying?
@@incognito7843 "What I think he is trying to say is:"
Who is the "he"? It's not Brian Cooley and it's not Brian Greene that gave any notion of, "This entire lecture is based on the non scientific string theory, it´s a possible mathematical model among 1000s of others."
Where was the math that showed it's possible? This video was one long wanking off to the god of nothing of showing no science (which includes math) for a multiverse and never praising God for this universe that we know of and all the info I gave to show such things can't happen naturally.
Take a stage with TED behind it, an audience who is wowed by a dumbass who made NO sense, and it somehow is important to people. Such things this dumbass mentioned can happen if only we leave our imaginations open. Gee, how scientific.

Humans: discover the multiverse
The multiverse: why do I hear boss music?
Atom 1: oh no i think i lost an electron!
Atom 2: you sure?

Humans: name "everything" the universe

Tiny universes: *chuckles* "im in danger"
Multiverse might be horrible! What if we travel alternative dimensions of our other same lives but worse copy of them 😱 just a sleep and wake up in another dim. Would be nightmare...
Ultimate Meme I don’t think anyone discovered the multiverse. It’s still a theory(a good one) but it can’t be proven with evidence.
Theoretically possible but there’s no way of proving it is possible.
15:00 THE BANG
Even though my comment will be one that is made by the ever expanding amount of 'nobodies' who have watched this video, I would have to say that this is THE BEST TED TALK I have ever listened to. I could seriously listen to this guy lecture forever and it really makes me wish I could have gone to college at some point. Though some of us are less fortunate than others we have people to thank, like this man, for providing the effort to teach us on a free platform such as this. Keep it up, Brian Greene, you're a very motivating speaker and you make my brain think of things on an existential level that most people couldn't bring out in me and for that, I thank you.
Check out Hugh Ross "Why the universe is the way it is" and "Improbable Planet" here on youtube.
Brian Greene is such a master of explanation and so passionate about the subject matter!
ricomajestic he is wrong in everything, well I have no underground for that but after some years please read my statement and you will think I was a genius 😉
I just love this...sometimes the nature of reality beacons from just beyond the horizon...
Wow Brian, I love you amazing content and intellectual forward thinking.
I like Brian Greene, he has an infectious sense of wonder and enthusiasm concerning the potential for further discoveries, as well as the gift for being able to convey the complex ideas that fuel that wonder and enthusiam to those who are not nearly as well-versed as he has worked so hard to be - but that was the most long-winded explanation of the anthropic principle that I've ever heard.
Translation: "I've heard of the anthropic principle before, and this is what Greene is describing, so BOOORRRING."
Reality: Greene is doing more than regurgitating the anthropic principle---he's proposing an explanation that justifies it as a valid scientific---not merely philosophical---hypothesis.
The problem with the multiverse based on string theory is that we are guessing an explanation (multiverse) for something not understood based on predictions made by another unproven theory (string theory).
Exactly !
Physics used to be such that you made a hypothesis about the real world and you tested it. If it disagreed with experiment or if there was no way to test it you would dismiss it or looked for some other explanation. Now, we have a theory that cannot be experimentally tested, and instead of looking for something that can be tested we say to ourselves, "Well, we cannot test that, but probably we can come up with another non-test-able explanation to explain the original non-test-able hypothesis."
Christian Farina So you're an atheist?
Yes.
what makes vibrate the strings?
Great talk . This guy is one of the greats for his ability to communicate such complex ideas and theories in such a " user friendly" fashion. Dr/Prof Paul Davies has some great ideas and insight about the Universe not only being fined tuned, especially being fine tuned for our kind of life (and all the support it needs) . He worth reading/listening to as well.
Amazing talk by Brian Greene.
It feels astoundingly incredible to realize that we are living in a remarkable time, where we know that we have lost much of the critical knowledge in the past due to cosmic evolution, and that our future generations will lose more such information due to ever expanding multiverse.
Deep space remains a deep mystery.
wut do u mean about multiverse
@@nerdonspeed3493you need to watch the video

I've always just loved his way of explaining things.
Had the opportunity to meet him in person. Wonderful guy as well.
this guys seems to love that presentation he is doing, like he planned for months, that makes me so excited
To get an answer with single approach to an problem is quite difficult sometimes. But at a same time it is quite difficult to forgo that path for which u spend too much of efforts.

It's quite disturbing to think that in an expanding universe, every passing minute the windows of discovery and understanding is not only getting more narrow but in some cases might have already been closed off to us forever.

Excellent presentation!
Especially the closing ideas
It's amazing how finally tuned the universe is to prevent life and destroy it. No where else in the universe have we found where life is possible and yet even here on earth it's a chance we even made it this far. The odds are against our survival from within the earth itself. Not to mention cosmic events that can end us in a flash. The universe is a very scary place my friends and we shouldn't think of it as a generous provider.
Entropy is our biggest enemy. Everyday is a battle against it.
Great description and reminded me of mel gibson young frankenstein film delivery, particularly the 'its alive' monologue.
flat eathers: the earth is flat
normal people: bruh we now believe we are in a multiverse
some flat earthers believe that the flat earth, surrounded by an ice wall that is endless, has other pockets of area like earth. So in their own way they have a multi verse theory. XD
@AllSeeingEye ofGod Atheism isn't the assertion that there is no god. They aren't claiming there is no god. They just don't believe in any of the ones proposed so far.
We are also normal people you dumbo and yes earth is flat
I believe in infinite number of universes with infinite number of realities but in non of them the earth is flat ...
@@user-rn5dl6tf8r haha you're so silly
The Universe, we have come to observe is indescribably amazing !The more you strive to see and measure it, the more it goes on expanding. Now, the concept of Universe is maturing in to Multiverse which awaits to be explored.
xdddddd Oh God.. What a bunch of stupid things.. If these stupid ppl really knows you... They will be terrified of your power.
I wonder how he feels now knowing that they found a stellar mass that red shifts older that 13.8 billion?
And not to get all theist, but how he compared handing down ancient records and how they would be perceived by the far future makes a compelling "the shoe is now on the other foot" argument for how we now view religion.
This was a good thought provoking video.
Simply amazing
One of the best ted talks ever
Science of the universe touches something inside like a dream which was interrupted by sudden awakening and can't be interpreted yet lingers in my subconscious and keeps appearing this time not as a dream but while I am fully awake. I give up on many things that don't make sense except the science of the universe.
19:40... interesting perspective. The evolution of cosmology is fascinating. Great video!
I'm glad you enjoyed it but to me, the mystery he posed is just another speculation. A spectacular one. Good show.
It's fascinating to consider what kinds of answers have already drifted out of our reach. We already can only refer to the observable universe for answers. Imagine a time when the entire universe was observable. What would the edge look like? What answers would it hold?
Brian Green is so good at explaining science because his passion matches his intelligence. But we must be sure not to get carried away. Everything he says here is speculation. The whole rests upon string theory and the strings themselves have not been observed. There are many equally smart, equally passionate scientists who dismiss strings. Greene and the others will keep working until we know the answers. That contention and that effort IS science.
I like finding documentaries titled with a question I already had.
Please make more TED talks like this
this man can tell you things that you already knew
but make it sound like you never knew them at all, with his passion
We are merely the explorers to the infinity in the pursuit of absolute perfection...we don't invent anything they already exists...
- The man who knew infinity
Perhaps it's the best quote fit for all of us .. maybe we never be able to understand the ultimate secret of the universe..but there is always a immense and unexpressible pleasure of defeating in such aspects..
I believe the quote is originally from G H Hardy's 'A mathematicians apology' rather than from the film. There's tons of quotes from his life & works scattered around ('if I were to prove you'd die in 5 minutes, I'd be upset but my sorrow would be very much mitigated by the pleasure in the proof') probably to please the ones who've read deeply into his life.
Incredible how back in the 1920's Einstein predicted what we now called dark energy!
+Neil McIntosh Einstein stole all his information lmfao. Dont give him that much props.
Let me guess he stole it from you! LOL!
ricomajestic
🤣..you probably killed him
Well the interesting part is that when he realised the equations of general relativity pointed toward an expanding universe, he introduced a new idea of a cosmological constant which would be a sort of "push back" force, which could account for the static, non expanding universe he knew he lived in.
Except not long after observation showed he was wrong and the universe is indeed expanding, at which point he embarrassingly erased the cosmological constant idea.
Then much later even, when it was discovered the expansion is accelerating (like Brian was talking about) the idea of a cosmological constant was brought back in. And while this constant accounts for the expansion of the universe (not the stillness of it) it's still very synonymous in many ways to Einstein's original idea. Even when the dude's wrong, he's right ay
Neil McIntosh there is no dark energy
Mind blowing presentation!
That "Peter Falk's Columbo style" finger is perfect for this mystery drama.
How can we be certain that we are existing in the most optimum time to know that what we’re observing, is everything?
depending upon the facts we know so far, if something new/different will come, we might say otherwise
Seeking Yu everything is relative, facts and our knowledge too
you sound like a cat that do not know but mabe you do.
JRR Tolkiens creation myth has the "Gods" creating the physical world thru music.. Always thought it was a beautiful idea but damn!
He actually has just one God. Eru Iluvatar. Manwë, Melkor, Sauron, Olòrin and the rest are all his creations, more archangels and angels of sorts that wield just small portion of power Eru does.
What about one God who created everything by speaking it into existence
Haha, yeah that's true. The strings are like the music!
Probably the best explanation of modern cosmology I've heard.
His excitement for physics is really lovely❤
It's so frustrating to be in that state of 'yeah, I think I get it!'
They are achieving a point where they won't be able to deny the existence of different forms of life. I can't wait for that moment.
Dr. Brian Greene never disappoints
As the number 1 is a massive logical underpinning so too is scientific explanations away from design and into extravagant explanations of the reason for a fine tuned universe.
My sister, Sophia, who's 8, has a similar response, and says she loves me "more than anything in the multiverse." These kids pick up on extraordinary scientific theories so quickly...
David Elliott
Unfortunately they pick up on anti-science quickly as well...
Maybe she likes watching BEN10
Certainly better to learn science (especially Cosmology) before learning about religious belief systems.
indeed
I’m okay when I gain weight - the universe is expanding.
Lol
It's the spacetime between matter expanding, which the matter floats in.
I've noticed a lot of RUclipsrs gaining like 15-20 lbs each since from about 4 years ago to now. A host from SciShow and Danielle from Animalogic as examples.
That ending blew my mind. Such an eery thought
this is disturbing to think about, we are infinitely more insignificant than we initially thought, and that the nature of the universe goes much further and deeper than our current understanding implies. excellent speech
Chicago isn't even fine-tuned for human life. If not for our fine-tuned environments we'd have all died this winter.
Joe Giuffre that comment just won the internet!

Because humans represent all forms of life. #sarcasm
Why does earth provide so many things we need to create the things we need to maintain life on earth
@Donald Pierce. Because during evolution, animal life adapted to exploit the things that earth provided.
I like how he says the question is why our universe is conducive for "our form of life" rather than simply "life". This is because the patterns we call life can be expressed in more mediums than the chemical. Perhaps they could be based on tangled lines of magnetic force, or patterns on the surfaces of neutron stars, or in other mediums we haven't thought of yet. It's easy to think of chemical life as special, so I say Kudos to Brian Greene for correctness, both physical and political.
Melinda Green it's all imaginary speculations. There is zero evidence for any of this, it all requires total faith.
Amazing talk I have ever seen
Brilliantly, elegantly, put.
Now this is what we call the most beautifully presented TED talk
I think we need many people like Brian Greene,Neil deGrasse Tyson.they actually make sciences interesting and inspire curiosity of mind about sciences.
degrasse is a hack without an original thought in his head
Manas Sharma that’s out of interest! The most important problem in all human history we facing is gender issue and hate speeches
brian weed is good. not recomended in the morning show with empty stomack
Thank you for the German subtitles ❤️
This is good information.
I like it a lot
it looks like the more theories we create and more data we collect, physics starts making no sense as we go more advanced.

It’s because they’re no longer doing physics, they’re doing philosophy. None of this is even falsifiable. It’s just mental masturbation at this point.
@@JPoleet he explained it in a philophical manner because everyone doesn't understand the math behind it . You are such an idiot to say this. How did they even find the amount of dark energy without the maths.
im not even interested in this but this guy was so interesting it became interesting
Jesse Ω same here! I started listening to Neil DeGrasse Tyson, Brian Greene and others, (and The Big Bang Theory :), now I’m hooked on astronomy and all of its other disciplines. I wish my school teachers had been half as enthusiastic as these guys!
Thats interesting
But what's more interesting than the origin of literally everything? People? I just don't get why it's not the most interesting thing to everyone
hes nowledege is as ablack hole that calls you on
@@8beef4u people have different interests, deal with it
I learned a couple things from this particular talk. Brian Greene loves the word "particular", and we are all floating around in a cosmic bubble bath.
Respect..👍 thank you Mr brian greene🙏
This guy has ridiculously good charisma and knows how to work the stage.
Teacher he is
imagine when you dream your soul takes a trip across the multiverses
I dream kinda like that
How can you believe in soul and multiverse ??

Astral Traveling. I do it all the time.
If your soul travelling across the universe after your death is true I'm gonna kill myself immediately
Everything can be calculated by gathering all frequencies and putting them into a "perspective". Simply drawing patterns will paint a picture of what is going on. This can be used for a next-dimension string of calculations that give some axis into what the parabolic stretching is.
Its really amazing. I love it.
great video. i've always wondered why the cosmological constants like gravity etc. work out just perfect for formation of stars, galaxies, planets, life, etc. this theory, if i understand it, is that big bangs are going off all the time, most of them fizzle and die because the laws of physics that come out of them, don't add up. but once in awhile, a universe pops up by random chance that has all the right rules and ingredients to make things work. i'm sold, i buy that explanation.
Naw, I still think it's turtles all the way down.
?!?!? think about the chances of each of these fine tuned conditions and add them up ..are the chances not astronomical ? pun not intended...basically the chances that it the whole universe, with all its fine tuned conditions randomly came about are next to impossible..if not impossible.
basically this leaves room to consider intelligent design
Granted i did not really this video but I've heard and read other things..

Sure, it seems astronomically unlikely that we would have the conditions necessary for life to evolve in our Universe. But the chances of an intelligent Designer just happening to be around are much smaller yet.

Next to impossible and impossible are highly different states. Next to impossible gives us a statistical possibility. This then, given time and enough events to have occurred, gets increasingly closer to a likelihood event. So if we factor in the next to impossible nature of our universe, we then factor in t, (time) and n(p), (number of events), this universe is as likely to of happened as its statistical eventuality, however small.
Impossible suggest absolute nothing. 0. Even the plausibility of a creator or intelligent designer is fractionally higher than this.
It seems you wanted to nurture the idea of intelligent design with statistical possibility whilst using that same technique to refute the same likelihood that our universe isn't of intelligent design.

Either you're responding to the wrong person, or I didn't make my position clear. I'm not arguing for an intelligent designer, nor for turtles all the way down, but for an unknown amount of order/information at the beginning, but probably no god.

After watching this video I want to study physics and go help humanity discover things but I know I'm way too dumb to ever be helpful
You're smarter than you think
But they are too smart to see the “dumb stuff” youll find. For example gravity - It pulls us all the time, so smart people will ignore it and be focusing more on something complex and unusual, like what causes a lightning, tornadoes, raining etc.
So we basically need both dumb and smart people because only then we can discover *everything.*
I played this video with a mindset to put it in watchlater
Guess wat....it was so good, now iam commenting
God bless you all.
