@darkw00d Reality is an illusion, the universe is a hologram

@darkw00d oh, and this is considered the multiverse theory by the way
-
@darkw00d oh, its actually fairly simple, i can explain that, just not the movie
-
@ceruleanspark Did you read "The Black Hole War," too?
-
@scribus I was quoting Gravity Falls. I don't *think* the "Is the universe a hologram" tests have come back either way yet.
-
@ceruleanspark Ah. I know Leonard Susskind put forth a heartfelt and presumably well-reasoned argument for it, but he didn't entirely sell me. Though, that might just be because I'm dumb.
-
@scribus They're testing it at Fermilab right now using some methods and equipment I don't quite understand. The gist of it though is that they're looking extremely closely at the fabric of reality to see if they can see the pixels.
-
@ceruleanspark Ah, that one. Susskind's argument was more about the amount of information that can be stored in one place and entropy. But speaking of pixels, I guess those would arguably be Planck units, wouldn't they?
-
@scribus For a given energy in a given volume, there is an upper limit to the density of information (the Bekenstein bound) about the whereabouts of all the particles which compose matter in that volume, suggesting that matter itself cannot be subdivided infinitely many times and there must be an ultimate level of fundamental particles, which Claude Shannon (Of "Shannon Entropy" fame posits to functionally be 1 bit. The holographic principle goes on to say that the entropy of ordinary matter is proportionate to its surface area, not its volume, because volume isn't real because the third dimension is an emergent phenomenon that doesn't functionally exist at quantum scales.
-
@ceruleanspark Yeah, that's about it. Susskind did go on about surface area being the deciding factor rather than volume, but I don't think he mentioned the third dimension being an emergent phenomenon, or at least not directly.
-
@scribus Well, nobody says anything directly in QP
-
@ceruleanspark True.
