Holographic Cosmology with Leonard Susskind - part 1
About | Information | History | Online | Facts | Discovery
NOTE: Audio clears up at the 8:20 mark Part 1 of a conference lecture given by Leonard Susskind on Holographic Cosmology. The holographic principle provides an extraordinary new picture of quantum gravity and the universe. Ideas are gradually beginning to take shape on how concepts like holography (and other deep insights uncovered in the past two decades) may lead to new fundamental principles for cosmology. Undoubtedly new insights will emerge on long-standing fundamental issues in cosmology: the nature of the big-bang, the initial conditions and fate of the universe. However, these new approaches will most likely lead us in new directions and allow us to formulate the "right" questions. This informal workshop will bring together leading researchers working in cosmology, string theory and quantum gravity to exchange ideas on recent progress and discuss promising future directions.

If people will watch this video in the future to see Mr. Susskind, they will wonder if video cameras were very rare in the first part of the 21st century.

"Season of mists and mellow fruitfulness!"
The Holographic Principle on the boundary can't possibly reproduce even all the information included in that one line of poetry.* I'm fed up with this reductionist nonsense which can't be tested. It's meaningless. I'm glad he mentioned Bishop Berkeley. That's pertinent. Black holes as mirrors? This will be scrunched information, not useable. In other words, high density in, low density like infra-red out. Eternal inflation? Now we're into Nietzsche territory! Sir Fred Hoyle must be rolling in his grave.
* That's because I can't know the associations it invokes in your mind, everyones different. -
I'm completely lost from 18:24 forward. Where can I start to learn this?

what kind of socialization produces a meat machine conditioned to arrive in such an intrusive manner. why are adults so rare? this is not solvable with QM. some kind of wet mess walks into what is being said @5:35. you missed the talk, stay outside and accept the consequences of acting like an adolescent selfish shit

Does the Everett interpretation of QM change something for the time of appearance of an observer?
-
The continuous changes in the camera view is terrible... very low quality work. Look at the lectures on theoretical minimum, and learn how to record useful videos.

What's with the insane camera switching?
Obviously someone is extremely proud of having multiple camera viewpoints he/she can play with but each is set to a slightly different color temperature, and each 'flares' on start-up.even the volume level goes up and down as if someone is switching mics too.
The lecture is fascinating - but it gave me a headache to watch it. -
Thank you for the video.

Is it possible that the apparent flatness of the Universe, is just a function of the 2-D event horizon of a 3-D Black Hole at it's center (i.e. The Big Bang)? The Universe is a Hologram! An ever axpanding event horizon that began 13.8 Billion years ago, and all information is encoded in the Voxels "smeared" across it. The Universe beyond "our" light cones may behave differently, but we will never know, since we can't ever observe them. ;)

Just Listen to how asinine this teachers logic thinking is..1-Cor 2:1-16.

Probability can be defined as the proportion of possible Universes in which a certain property holds given some other properties. e.g. For all the universes in which exist the Milky Way galaxy, the planet Earth, a casino, and a gambler who has the brain configured with the memory of just having rolled two dice. The proportion of Universes in which the pair of dice on the table will be snake-eyes will be 1/36 all things being equal.
One can calculate this as the sum of all histories of the Universe from a presumed unique big bang state.
So I don't see any conflict here with the observer being part of the system in quantum mechanics. Just that one could never calculate exactly such a big system only approximate it with heuristics. Just like no dice is exactly perfect.
I believe this is called the Many-World interpretation of quantum mechanics. I thought most physicists took this view. The "collapse of the wave function" with god-like observers interpretation is very old fashioned. -
Lenny's so cool. Homeboy early on, regarding the computer thing, was being a dick.

Can we get a better quality than 240p upload pls?

(1.)You would think that Stanford could afford an HD video camera... and this is pathetic. (2.)The 'bangers' seem to be getting restless and frustrated with their own tired fairy tale, very interesting....(3.)Also, if the universe is 1000 times bigger then the present visible portion (I agree on that) then the big bang could not have happened.

Susskind is in a league of his own. His indefatigable enthusiasm for cosmology is infectious and the impress of his teachings and generosity of spirit has left an indelible impress not soon to be equaled. Thank you, Leonard.
