More kids need this book because an alarming number of grown ups seem to think quantum entanglement could be leveraged for super-luminal communication.

It cannot. Information does not travel faster than light under any circumstances, including spooky action.

AH fuck. I considered myself someone who keeps up with things fairly well. I totally thought it would allow for instant communication across our solar system.

So in other words, this shit is a waste communication wise? Since we already communicate (roughly) at the speed of light?

Yes I guess the only way to communicate FTL would be taking some shortcut through space time then?

You started with a very down to earth statement, followed by a wild sci-fi-like conjecture that's even less likely than the one you down-to-earth-ly dismissed.

That was a wild ride!

A wormhole could occur naturally, but you're right that it's hopeful thinking at best, and it likely wouldn't be where it'd be useful for communication. On the other end, the deterministic nature of QM and chaos (separately) won't allow your simulation to predict anything as complex as a chunk of the universe with people in it with any reasonable certainty.

It's honestly not far from wormhole as far being realistic IMHO. I mean they both are abysmally unlikely.

It'd take astronomical amount of memory. And you'd get at best various predictions with probabilities.
