20:05 "Sometimes, nature guards her secrets with the unbreakable grip of physical law." Beautiful.

His enthusiasm is so infectious!

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.

god I love theoretical physics!!!

stuff like this makes me tear up because of how little we understand

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 ..

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.

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.

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.

Given that we don't even know how large our own universe is I can't imagine there NOT being a multiverse

How incredibly interesting!

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.

Tesla once said everything can be thought of as vibration,frequency and energy.I can relate it to this video

I love this speech. I've watched it many times. It's absolutely fantastic.

brilliant, he who remains brought me here.

I think my mind just had a Big Bang.

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

This is definitely what i need. It feeds my soul.

Got goosebumps. Made it more wanting to become a cosmologists

Just want to say never hesitate to question the best and the greatest minds. As you might be correct somehow.

How incredibly has he explained the possibilities of unimaginable things!

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.

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 !

Brian Greene! He has such great inflections in the way he speaks, similar in ways to NdGT. Mind blown, as usual!

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....

i love how much he gets into it, true passion

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.

Human lifespan feels like a blink when we think to explore the universe

20:10 "The true nature of reality beckons from just beyond" TED Radio Hour Intro

So there could be some kind of Goldilocks zone for universes :0

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.

Basically gravity is still in effect while we are still under the acceleration of the big bang theory.

Excuse me this video has only 39,280 views and 791 likes? What the fuck is wrong with the KZfaq community? This is the most intriguing video I have ever watched on KZfaq.

This is was a fantastic lecture. Not only is it brilliant and groundbreaking; but it’s even engaging.

This is the first time someone explained dark energy in a way that's easy to understand

Probably the most amazing thoughts and theories of a multiverse. This why is I believe a multiverse can exist

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.

Brian Greene is the single most brilliant speaker in the history of history

we need more science communicator like him

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! 😂

@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 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 🥰🥰

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

I don't understand much of it, but I love listening to Brian Greene.

I hate being curious, I want definite answers God dammit 😭

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).

Wow, Im working on a housework and I just noticed this is the guy of one of my books I read x).

Update : The large hadron collider was unable to find anything supporting the string theory.

"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.

When he mentioned gravity I thought he was going to say that the gravity of the other universes is dragging ours apart.

Not only don't we know what we don't know, we may never know what we cannot know.

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.

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.

Please provide us subtitles, thanks

loki series brought me here and i'm amazed at the possibility of multiverse actually might be existing

This is best ever done by Prof. Brian Greene

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?

This is interesting. I'm happy to be living in a dynamic cosmic symphony.

love this guy's enthusiasm!!!

12:37 Asking wrong questions. Brian is a genius.

"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 :)

18:32 is a scary thought.

(inside our simulation control center) Hey Bob, they’re starting to catch on. Oh? (Adds 500 zeros to possible dimensions) That should slow them down a bit.

Really privileged and blessed with the talk too

Well, the center depends on where you're observing from, so you're always at the center of your observable universe.

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.

He is a good story teller and a science fiction writer!

This was remarkable. I loved it

As he mentioned in an interview "the cosmos is not ours to understand"

Imagine living 2 billion years go, the universe would of looked so different

I've never ever hear such type of thoughts thank you Brian greene

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.

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 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 😻

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.

I go through many books, but love to hear prof Brain green's lucter very much.

Im just excited for Dr. strange: Multiverse of madness 😀

what if the universe's are different shapes

Thank you brain ❤️❤️❤️ loved this explanation 😘

Watched his string theory video on discovery long back. At that time that was the best thing ever.

Damn, Data gives some good presentations!

If you’re new to these ideas, and want more, read “The Goldilocks Enigma” by Paul Davies.

Brilliant !! I am truly touched.

good approach and beautiful technical background but Also think and understand about iota energy in very cold temperature

That Was Fantastically Awesome. Whooooaaaaa

So, lets figure out how far this will go with this youtube recommendation chain. I was impressed by the fact that seemingly there was 25k people who came from scythe lady video to the scythe festival one. From now on i am going to watch next 100 videos with this comment numerating my path. This is comment №95

This is one of the best Recommended videos in KZfaq

Awesome video it increases my knowledge and interest in cosmology

anyone else felt goose bumps!

this video gave me chills. such an amazing place we live. reality is so much more interesting then "god did it."

Thanks Google and all comments Boss 🙏 Dropping my knowledge

The idea that in the far future we might lose all this knowledge terrifies me. How utterly depressing

I just completed watching LOKI KZfaq Algorithm: Recommend this video

woah, this is sick

WOW,THAT JUST BLEW MY MIND!!!!!!!

Mind blowing stuff. Fascinating.

I'm getting the strange feeling that he is trying to sell me something...
