The Nature of Space and Time | Brian Greene

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.

Perhaps our understanding of gravity, currently GR, is not a complete understanding and there is more to the story, yet to be uncovered?

    What a crazy universe we live in. I guess Douglas Adams got it right: "There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened."

    Stefan Hensel , Any theory however advanced it may seem can never go further than the understanding of a human mind. I also wonder if we are not discovering what we already know. When I remember my childhood I ask myself: Am I the same as I was? but... if my mind couldn’t remember... so... What is all we see?

    Brian is a joy to listen to. A wonderful communicator and a very good person. I don’t have a science or mathematics background but still I’m interested. Just one question, so much is theoretical physics based on ideas and math. A little more applied physics would help me to understand and then perhaps buy in.

    The title should be changed to include some mention of black holes, since THAT is the actual topic of the talk. That said, I just finished "Einstein's Monsters: The Life and Times of Black Holes," by Chris Impey a few days ago and, sadly, most of it went right over my head. This talk, with its amazing graphics, filled in most of the gaps. Brilliant!

    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.
