- Is there more than one universe? In this visually rich, action-packed talk, Brian Greene shows how the unanswered questions of physics (starting with a big one: What caused the Big Bang?) have led to the theory that our own universe is just one of many in the "multiverse."
Talk by Brian Greene.
20:05 "Sometimes, nature guards her secrets with the unbreakable grip of physical law."
Beautiful.
What are you doing after this mysterious number " 7 " Years ago
so we break the laws of physics🤷♂️
@@ILLUMINATO01 It's not that we break the laws of physics. It's that we discover that it wasn't a law in the first place, we just thought it was due to our current/precious limitations.
@@DEEPAKKUMAR-ch6cb I'm eating breakfast in bed.
@Michael Antonio welcome to future after 7 years..
His enthusiasm is so infectious!
That's how anybody would talk if they were living the dream!
😂😂
I wish I could talk like that. Not talking about the intelligence and knowledge, which I am jealous enough of, just his ability.
@@johnphantom that's what only few had mastered
@@arpitb75 I think it is more of a gift than mastery.
Never ever have I watched such a beautiful engaging Ted talk. Honestly it was the best talk ever. The way he presented everything was even more beautiful. Even I believe in the multiverse theory but then it makes us question everything we already know . It puts to test all our beliefs The universe is truly a mystery and so are we.
blessy george it’s incredible!!
No one knows that humanity would ever conquer our galaxy or we would just be stuck inside the solar system. No one knows the future.
Truth!
@@halweilbrenner9926 right
Have you watched 'World Science Festival' channel on TH-cam? This guy founded it.
How incredibly interesting!
yes it is.And now i feel why did not i watch the video before.
Omniverse is the ENTIRETY of multiverses which the INFINITE universes define.
god I love theoretical physics!!!
You funny 🤦☮️☯️🎭
No she not god made the universe.
Bro i am going to become soon
I was born one. Lol
Me too....and Metaphyics !!! Even better stoned !!! 🤔
I have read lots of books and seen lectures on theoretical physics but clearly he is the best. His books and presentation akes me want to switch my major from medicine to physics ..
Biochemistry is more lucrative & applicable to making life more survivable
Please don't. Pseudo science has less chance of being real than Avenger saving our planet from aliens.
@@halweilbrenner9926Don’t you know Earth will not last forever, and we have to evacuate from it sooner or later. Hope biochemistry saves people lives then.
stuff like this makes me tear up because of how little we understand
It makes tear up because, I believe in the multiverse model, there is so much that we haven't discouvered that we don't have a way to discouver right now
How does not understanding make you tear up, tf
@@rattlebbones6651 she doesn't know why she tears up. What a vicious circle of pain she's feeling...she'll either dehydrate or suffer the most extreme depression known to ever exist.
Kinda makes me tear up not knowing how she'll deal with it...
@@user-dx4br5gd1r That really puts her name into perspective.
@@huey6944 all of you are such losers lol
This is really freaky. That would mean we cant exist outside the bounds of our own universe, since we are made like a programm that works only on that particular machine. It would mean that everything is bound to its own universe and simply cant exist anywhere else. This is kinda depressing, there goes the idea of traveling to one lol.
Zevin X Yes, that's true. It's just that this never hit me before while thinking about multiverse.
nanotech2080 Yeah for sure, it's mind boggling to think about. Not to mention life as we know it is just that as we know it. We have barley even traveled off of our tiny little rock in our tiny speck of a solar system. It might turn out that the "Goldilocks zone" really only applies to our type of life that specifically evolved to adapt to our specific environment. There could be gas based life, non carbon based life, life in the center of frozen planets kept warm by the planets molten core. Life could be a inevitability caused by energy, meaning sun's could even be "alive" just not in a way we currently comprehend. Now this sounds like crazy science fiction and it may be, but the universe just gets stranger the more we discover, and we keep adding pages to the book of science.
Well, it's a bit different from a place, where even our periodic table would not be possible, or elements in general.
What if someone tried to travel to another universe and just...dispersed...or collapsed. What are the chances that we will be able to create something that exits our universe as it expands ever faster and our technology might not keep up?
Pretty late answer but if there could be so many other universes, maybe if we die, we get to live again, but in a different universe?
Prof Brian Greene is a brilliant and engaging speaker. Recently I read his book The Elegant Universe. The book, though dated by now, goes far deeper into the subject. It is a good introduction to Relativity theories,Quantum Mechanics Standard Model and Super String Theories.
Humanity is capable of incredible thoughts and scientific achievements despite being a breakable, fragile form of life, limited by our physical form to live in a very small spot in the universe and for a very short time.
beautiful-
I fact that I find Physics hard and that for the first time I understood it so well without feeling dizzy, is just mind boggling.
Because you haven't seen the math yet
@@uddhavgokarn357 😂😂
So... instead of feeling dizzy you're feeling mind boggled? I'd probably want to rethink that thought into one that made sense.
Given that we don't even know how large our own universe is I can't imagine there NOT being a multiverse
We are even smaller than a microorganisms (much much much smaller) in terms of universe.
Before contemplating other universes, please explain this one.
Does size even matter in a multiverse? Maybe Horton did actually hear a who?
Wrong question, what do you mean by large?
I can tell you very confidently that this man does not know about the universe more than four five years old thinks of Avengers being real. This is bs and pseudo science should not be taught as being real.
I love this speech. I've watched it many times. It's absolutely fantastic.
Tesla once said everything can be thought of as vibration,frequency and energy.I can relate it to this video
Imagine in future there are no stars twinkling but only darkness and ppl may be thinking stars don't exist because they never saw them
I don't think people will exist without stars
Not our species at least
If stars die,a blackhole is created ,and it sucks matter,even light.
Multiple other factors that planets will not exist
Edit:I just got what you said ,I do understand it
They probably wouldn't spend so much time dreaming about a new world, and used their home planet properly and respectfully. Maybe it would be better that way.
I think they will believe that these things existed, as yes it's "ancient" data, but this data will always be conceived as true and as today's scientists grow old and die, they will prolly tell their next generation that these proofs are infact true and correct, and the reason behind and the way we found it out, and maybe who knows, if we were at today's tech and knowledge a few million or even billion years ago, who knows what we could see, maybe even the edge of the universe? We could maybe even graph the entire universe and properly study it, and maybe then we can get a theory of everything, but sadly it's never gonna happen
We are the future itself. Time only exist to us
We wont be seeing an empty dark sky, beacuse the stars in our galaxy will atleast stay they wont be dragged away beacuse of the expanding force. So dont worry they will know about the stars.
This is definitely what i need. It feeds my soul.
How incredibly has he explained the possibilities of unimaginable things!
I think my mind just had a Big Bang.
Ok.
Wow
How big is it now?
@@Gingnose or how small it is
Reverse Big Bang
Probably one of the best ideas we have about the universe with the current evidence. And a real problem to the scientific method if future humans remain stuck in the milky way.
Brilliant lecture...I’am an engineer and know basics physiques I was taught how Nucleas Reactors work...but he takes me into outerspace where we can’t measure anymore or even down to the tiniest level where can’t measure anymore...amazing stuff! Happy to be able to graps what he is saying...and making me aware that getting my groceries is what I have to do daily....
Got goosebumps. Made it more wanting to become a cosmologists
brilliant, he who remains brought me here.
Bruh 😂😂
This dude is a kang variant
Lmaooo😭😭
You can’t kill me because I already know what’s going to happen
Just want to say never hesitate to question the best and the greatest minds. As you might be correct somehow.
We need more people like Brian Greene and Neil deGrasse Tyson , those bring science into a non science public in an understandable way! That's what people , especially children needs !
i love how much he gets into it, true passion
Brian Greene! He has such great inflections in the way he speaks, similar in ways to NdGT. Mind blown, as usual!
@Brian Greene, your way of communicating it’s just magic. You make it sound so simple and understandable, it could be a language of its own. Thank you so much for your passion and enthusiasm, and for existing. Big fan 🙌🙌
I recently stumbled upon Prof. Brian Greene' talks and books. His explanations are so engaging and captivating that it always encourages me to study and learn more about the universe and its secrets.
I hate being curious, I want definite answers God dammit 😭
Welcome to science man. Science lives in the unknown.
Please don't use the Lord's name in vein.
@@BennyNegroFromQueens from what we can tell from the present evidence the lord doesnt exist so it doesnt matter.
@@unseeneye1 oh yea...what evidence?
@@BennyNegroFromQueens exactly.
This is was a fantastic lecture.
Not only is it brilliant and groundbreaking; but it’s even engaging.
So there could be some kind of Goldilocks zone for universes :0
I dont think its like a solsr system, but i think its similar in that some universes are too extreme for life, but some others sre just fine for life
Probably the most amazing thoughts and theories of a multiverse. This why is I believe a multiverse can exist
You didn't finish your thoughts? You ended with "this is why I believe a multiverse can exist" and then nothing? Tell me your thoughts on why you believe what this speaker made perfectly clear sense to you.
@@user-dx4br5gd1r doesn't it make sense to you?
@@zz.des1 "this is why I believe a multiverse can exist"...why? They never said why.
Do you not understand that what was said was an incomplete thought? If you don't see or understand that...well....yeah, you'd be an easy sell on the idiocy of a multiverse.
tEll mE yOuR thOUghts On wHY yoU blablabla goh 💀 out here tryna start some bs
@@user-dx4br5gd1r the "why" is the video bro did you watch the thing?? they commented "this why i believe multiverse can exist". that comment is literally under the video about why. that is so not hard to comprehend what are you on
Regarding the last point he makes about how future astronomers won’t be able to tell that there’s more space out there makes me wonder if maybe the reason we can’t figure out Dark Matter & Dark Energy is because something is missing that we won’t ever know about simply because we came along when we did and that window has long passed us.
He is such a fantastic speaker. I love listening to him. He's so captivating.
I love smoking cannabis and then having the great minds of Ted talks pick my brain apart and then put it back together! 😂
Wut
I just sniffed ketamine and he has pickled me lol
I do methadone
🥶
@ibrahim hamid
I don’t smoke cannabis for a good time I smoke it because my brain takes advantage of it and starts homeostasis in brain to help me regulate! The fact that one feels amazing when smoking cannabis is just natures way of taking care of you learn more about your brain chemistry and how your brain goes into a state of homeostasis when you consume cannabis.... mouth breather 🤦🏽♂️
I am sure that with the knowledge you have, your life and thinking would be freakkkkin' awesome, needing no one but your mind and its imagination to keep that spark of excitement always alive in you. I always believe that the one who explains physics in a way that a layman with minimal knowledge of physics would understand, is the one having a deeper understanding of the same (as believed by Richard Feynmann too).
Excuse me this video has only 39,280 views and 791 likes? What the fuck is wrong with the TH-cam community?
This is the most intriguing video I have ever watched on TH-cam.
thats because people are trying to find out what color is the dress
Victor Alejandro ...and, most important, there are no kitties involved
***** it has 18 dislikes.
I came in the comments looking for this comment.
Yes sir

"The true nature of reality beckons from just beyond"
TED Radio Hour Intro
I don't understand much of it, but I love listening to Brian Greene.
I want to meet him the way he teaches is awesome I am now 10 th but after watching his 4-5 video's i understood the Enisten and string theory 🥰🥰
This is the first time someone explained dark energy in a way that's easy to understand
love this guy's enthusiasm!!!
This is best ever done by Prof. Brian Greene
Human lifespan feels like a blink when we think to explore the universe
Please provide us subtitles, thanks
Thanks are due for speaking simple and clear English making it easy for an eastern student to pick everything easily.
Brian loves what he does. He goes right into his subject.
Basically gravity is still in effect while we are still under the acceleration of the big bang theory.
we need more science communicator like him
Awesome video it increases my knowledge and interest in cosmology
This was remarkable. I loved it
I’ve played with the idea of a multiverse and the idea that if there are infinite universes then there must exist universes identical to each other, and while this is possible, there is also the possibility of infinite universes that aren’t like each other one bit. Let’s look at something as simple as our natural numbers. They go on infinitely in a positive and negative direction however while there are an infinite set of numbers not one value repeats. The odds of finding a number identical to the value of 1 are 0 and that goes for any value.
And as far as dark energy goes; with our current laws of physics we can’t create nor destroy energy however it can be manipulated. Could there be a way to someday manipulate dark energy and would doing so damage or better the universe we live in?
18:32 is a scary thought.
Bruh why am I just now getting this on my feed??? Better yet why after watching the finale of Loki????
his storytelling and clean, concise, and clear explanation of something so complex and nuanced is a credit to his truly and absolutely deep understanding of the theory.
Just in line with this, there can be a possibility of being multiple big bangs having their own set of multiverses - one more level deeper
Wow, Im working on a housework and I just noticed this is the guy of one of my books I read x).
WoW, this theory is super cool, it answer the so much asked question if there are many other universes out there. The real question is why there is more matter then antimatter in this universe. For any universe to start their existence MUST have the perfect explanation and to explain why it also must have the perfect questions. Why the universes are created and what is between universes.
Really privileged and blessed with the talk too
It’s easy to see how the universe is expanding at an increasing rate. We are surrounded by dark matter even here on earth quantum physics proves it. In fact; what we perceive as solid is far from it.
Between every atom there is space. Inside of every atom the subatomic protons, neutrons, and elections have space between them. Even smaller particles called quarks and leptons have space between them. So considering the density of subatomic particles being suspended then the infinite amount of dark mater is what is pushing the universe apart.
This is interesting. I'm happy to be living in a dynamic cosmic symphony.
Thank you brain ❤️❤️❤️ loved this explanation 😘
Brian Greene is the single most brilliant speaker in the history of history
it's sad to know that future astronomers will forget our discovery and knowledge about other galaxies and how big and old our universe is , or dark matter, string theory etc, just like we ignore cave men's drawings of gods and aliens visiting.
I like that analogy.
They won’t forget.. never make another comment on TH-cam please 👎
@@almostrich4013 they will, that’s how it’s always been
@@joker3053 I don't know man, cave Mens drawings were drawings whereas there is recorded evidence of this eras findings and even if they cant understand our languages there are saved mathematics and codes we have created that are binary that they should understand. Plus some people belive the Carmen's drawing and are extremely interested in them and research them so what's to say future people wouldn't do the same and unlike cavemen there is much more evidence of our eras inteligence, not to say cavemen weren't also intelligent as they did set the ball rolling so to speak
this makes very little sense. I'm worried that so many people liked your comment.
When he mentioned gravity I thought he was going to say that the gravity of the other universes is dragging ours apart.
WOOOAAAHHH
What an idea!
i thought the same thing
I've never ever hear such type of thoughts thank you Brian greene
Anyone know who created those great videos, and where they may be available
The greatest minds sometimes come to the conclusion that the more you start to learn and understand about our reality, you conclude that you know relatively nothing bc we can’t fathom infinite wisdom. There will always be finite limits to what you could possibly know, yet there are infinite subjects that you will never remotely understand or comprehend.
Update :
The large hadron collider was unable to find anything supporting the string theory.
But we found "evidence" of another universe that collided, but we can't really know if that is it or another phenomena
@@user-ib1dx4dh3n But there is also evidence that the eridanus supervoid caused the CMB cold spot, and not another universe
@@tres-2b299 I'm aware of that
They don't even know how to test let alone finding any proof, it will not happen
its not big enough....not enough energy
Brilliant !! I am truly touched.
Mind blowing stuff. Fascinating.
"Which means that we are living through a remarkably privileged era. When certain deep truths about the cosmos are still within reach of the human spirit of exploration. It appears that it may not always be that way." This made me so sad, one day these records will most likely be lost, and that hurts my heart. We are probably meaningless in terms of a multiverse, which I think is ok, we just have to accept our role.
That Was Fantastically Awesome. Whooooaaaaa
This is one of the best Recommended videos in TH-cam
"the true nature of reality beckons from just beyond of the horizon"
eventually I understood what's talking about and who's saying these words at the beginning of each TED Radio Hour episode :)
Well, the center depends on where you're observing from, so you're always at the center of your observable universe.
True but also we know the sun is the center of our solarsystem. But it isn't the center of the Milkyway
If you’re new to these ideas, and want more, read “The Goldilocks Enigma” by Paul Davies.
That just blew my mind!!!!
Not only don't we know what we don't know, we may never know what we cannot know.
I think I was about 10 & tried to read a book by him. I'm sure I had no idea what he was talking about but from that day forward I've been interested in Physics.
He's cute too 😻
You work with physics ?
WOW,THAT JUST BLEW MY MIND!!!!!!!
I've just come to accept my role in this universe, I can't take more than I return and I'm just a momentary blip in the grand scheme of things. My existence means nothing, and this really helps me keep myself happy and content with all the thing in and around my life. The unimaginable beauty and mystery of the universe is just that beauty and mystery, I like her that way. Stay humble and curious friends.
I'm getting the strange feeling that he is trying to sell me something...
He's selling you on the idea of a multiverse :-p
Ikr, he seems kind of like one of the guys you'd see posting videos on his get-rich-quick website for 24.99 a month
Cheesyc that's the sign of a good communicator.
this video gave me chills. such an amazing place we live. reality is so much more interesting then "god did it."
Stabbing Squidward that’s what makes God interesting. God made all of this.
@@Rich-je9fy proof?
@@Rich-je9fy
This is what you believe. Maybe multiple Gods did it, maybe Aliens did it, or maybe it happened without a God, like Evolution did. Without evidence you can only say "I BELIEVE that a God made all of this".
god is one of the dumbest myths ever
Wow - so inspiring talk🙏
He is a good story teller and a science fiction writer!
Imagine living 2 billion years go, the universe would of looked so different
Damn, Data gives some good presentations!
Watched his string theory video on discovery long back. At that time that was the best thing ever.
What a fascinating lecture 😊
As he mentioned in an interview "the cosmos is not ours to understand"
Indeed it isn't. There's only one being who is meant to understand it and that's the genius who created the cosmos to begin with... God
5:24 anyone else think of the Misfits?
138 is everywhere. "We are 138"
The best of Brian.
Thank yooou Long Beach I love you too, peace and love, Dougy :).
anyone else felt goose bumps!
what if the universe's are different shapes
Incredible talk!
I have been looking all over the internet to see if there could be a universe without strings, and I really thought this would answer my question. darn it, I have to keep looking.
Why are you looking all over the internet to see if you could find a video about the universe without strings? That's oddly specific.
woah, this is sick
If the level 1 (quilted) multiverse contains an infinite number of copies of me and you, does it also contain in real space copies of fictional characters, like, say, Sherlock Holmes or Captain Ahab? As long as they can physically and logically exist, do they?
