The Holographic Universe Explained

Here's a video that made me feel like I almost half-way understood one of the main underlying principles (AdS/CFT correspondence) [VIDEO] re: "Following the discovery of this duality by Juan Maldacena" Semi-unrelated: If you like articles like this, I bet you'll love that whole channel.

PBS Space Time have done a number of episodes on the holographic principle[1] I strongly recommend anyone interested in physics check out the channel [1] [VIDEO]

There's a lot here but this specifically talks about AdS/CFT which seems to be a pretty core concept [VIDEO] Just linked this on a similar information theory thread [1] (glad it's so popular on HN right now!) 1: [LINK]

I'm not sure why you're being downvoted. It's not an unreasonable question/thought. The heisenberg uncertainty principle says we cannot know both position and momentum perfectly at the same time where I believe your comment is originating from? In theory, if we perfectly know the quantum information then a system's state is perfectly reproducible (probably not us... ultra aliens?) since no quantum information is ever lost (probably...). To my best understanding, this is the idea of the holographic principle[0]. [0] [VIDEO]

I think that's the million dollar question. :) This episode touches on that a bit (but not really), and we're getting into holographic universe theory - [VIDEO]
