Recent results in the study of black holes and string theory suggest new perspectives on the nature of spacetime. In this talk, these advances will be explained and illustrated visually.
Brian Greene is a professor of physics and mathematics at Columbia University, and is recognized for a number of groundbreaking discoveries in his field of superstring theory. His books, The Elegant Universe, The Fabric of the Cosmos, and The Hidden Reality, have collectively spent 65 weeks on The New York Times bestseller list.

@@ireneduncan863 He's lying about physics. Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 is F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. A PHOTON may be placed at the center of what is the Sun (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light (c); AS E=MC2 IS F=MA; AS ELECTROMAGNETISM/energy is gravity. The stars AND PLANETS are POINTS in the night sky. The ultimate unification of physics/physical experience combines, BALANCES, AND INCLUDES opposites. E=mc2 IS F=ma. This necessarily represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Gravity IS ELECTROMAGNETISM/energy. GREAT !!! GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/AS) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/energy is gravity; AS E=mc2 is F=ma IN BALANCE. BALANCE and completeness go hand in hand. It ALL CLEARLY makes perfect sense. By Frank DiMeglio

HUGE intellectual win for me tonight. For 20 or so years I have been trying to fully understand black holes--and I mean really understand the minutia of their genesis and existence. Tonight, I found a lecture which included a most amazing video graphic that opened the door and allowed me to truly comprehend what black holes are. Further, it clarified the idea of the fabric of space, and clued me in on the missing concepts I have had in understanding both gravity and quantum entangled. I feel like I won a million bucks. I learned more tonight than I did in a physics class at university. I shouted out loud when I had my "Eureka" moment watching this and probably woke my neighbors. It's been an exciting journey!! Dr. Brian Greene has been a favorite of mine, and once again he demonstrated why that is, in his latest lecture. Dr. Greene please come to NYC for a lecture.

He is good, isn't he! However, I still do not think that any theory completely explains or truely understands Black Holes or describes what happens as our current laws break down in the centre of these amazing phenomena! Perhaps our understanding of gravity, currently GR, is not a complete understanding and there is more to the story, yet to be uncovered?

wow .. his talks have unique style and are separate from others in that he emphasizes on the questions our curious minds ask like HOW does gravitation pull occur in empty space, is black holes just a theory etc., and the ending on quantum entanglement is genius .. thank you sir

First off. Thank you professor Greene. I enjoyed this last hour. Also Thank you for the headache it gave me. I have for some time been thinking about things such as was discussed. I had many years ago a rudimentary education in Calculus, Abstract Algebra and Physics. That being said I'm way behind what has taken place over the last 50 years or so but my interest and curiosity has not waned.I have always thought that since Spacetime itself may be the actual foundation of our Reality we can never really know What,Why and Where we are and where we may ultimately be going without a clear understanding of The Nature of Spacetime itself. Several things have come to mind while thinking about Spacetime not the least of which is the following. 1.Could it be possible that Spacetime does not have a "uniform Density" throughout our Universe? 2.If Spacetime were in fact to have areas of differing densities could some of those areas be connected to the concept of "DarK Matter" and its apparent effect of controlling the distribution of Matter across Spacetime. i.e. Could Dark Matter be more of a "result" of Density differences in Spacetime rather than an expression of some unseen Material Existing "within" Spacetime? 2.If Spacetime does indeed have areas of Greater and lesser Density would light travel through those areas of differing density at the same speed? 3.Could something exist that I have come to call "Negative Spacetime" and if it does exist what would be its effect or effects on Normal Spacetime? 4. If wormholes do exist then there must be a point at which the "fabric" of Spacetime is ruptured and if this is the case then what would Spacetime look surrounding this point of rupture? These are just some of my thoughts. 5. Also while I am at it there is one more thing. Would it be possible that the observation of the existence of Dark Energy is the result of processes taken place at the singularities of Black Holes where by Energy is being fed into Spacetime itself from those Singularities. Why I am wondering this is partly because of the fact that Dark Energy seems to be increasing in strength over time and that may be correlated to the increase in the number and size of Black Holes over Time? I keep thinking back To "Energy can neither be created or destroyed". If anyone would care to comment or perhaps direct me to someone or place where I might become better informed it would be greatly appreciated.

Always the same old kind-of wrong stuff. We need to start talking more about quantum gravity already (the stuff he mentions at the very end). Things come out very differently in that research. Like, dark matter even goes away, being revealed as an artifact of a non-quantum description of gravity.

Well, there is certainly some brisk disagreement about the essence of our apparent universe/space-time. Since you're listening to BG, here, you're probably aware of dissenting interpretations and neither of us grunting, smashing apes (not monkeys) should imagine ourselves competent to understand or interpret the evidence.

That's very binary of you. I didn't vote to dislike this video, but I'm skeptical when somebody gets that true believer smile on his face and talks about scientific theory that hasn't been proved. Halograms? That's a theory without proof. We see that in the string theory talkers. Waiting for proof. The theory that the earth is round was laughable until Magellan's crew sailed back into port. And the black hole theory was just a theory until they could observe the orbits of stars at the center of the galaxy. So, I'm waiting, because just because there is a theory, and it makes sense on paper, does not mean it's real. Some scientists think the galaxies are connected by electric forces. I'm waiting for the proof. I dislike belief. The last 2 people I want to hear belief talk from, is politicians and scientists. The scientists should know better. People want to believe, especially if it's told by a skilled speaker. See the responses to this video for some of that action.

I expected this answer, as I've received it before in under a political video. They posted up with, "The 3 people who voted this video down work at CNN" My rap was that I didn't like it for several reasons, which I laid out in a clear manner. And his response was, it was just a joke. No. Your response is a statement that only kooks would vote down this video, and it's simply not the case. Green is selling this theory, which he might believe in, but I don't like belief....also, he might be selling his book. He's a good salesman.

​ 03chrisv - Thank you for your advice. I am from a century where criticism wasn't put down as being "too serious". We developed a tough hide and were expecting criticism, knowing that people have difference of opinion. In this century, when criticism occurs, people think it is an emergency of some sort, and feel the need to circle the wagons, as if they are being bullied. I think it's stemming from the schooling, where conformity was stressed somehow. People value conforming to the group over discussion involving differences of opinion. When you post on the net, you should expect difference of opinion. If you disagree with something, tell us how or why you disagree. To defend a statement that is under criticism as 'just a joke', that may or may not be valid. In this case, the so-called joke sent the message that any disagreement would have to be kooky flat earth types. And when I'm told to try not to be serious, what is taking place is I'm being told that criticism or difference of opinion is invalid.
