Randomness and Bell's Inequality [Audio only] | Two Minute Papers #31

In this episode, we discuss what makes an event random, and how incredible it is what Bell's theorem (or inequality) has to say about truly random events.

Note: "local" means that information from the hidden variable doesn't travel faster than light.

UUhm but what is this thing that proves it's completely random? The video just cuts off at the good stuff

[zzador]

If you want to look it in that way: Even in nature there is no randomness. Everything is just cause and effect. Even radioactive decay can be deduced to cause & effect. So every apparent Randomness is just a causal effect on the initial seed before the big bang i guess.

I first thought about this about 13 years ago and have been under the impression that nothing is random (given a computer bigger than the universe).
I haven't heard of Bell's inequality theorem until today and after looking into it I don't understand how it proves randomness.
From what I understood it disproves Einstein's paradox, which would help the randomness' cause, but not prove it.
If anyone has any useful links or help me understand this better, that'd be great.

Bell's inequality theorem is surely one the best genius strikes ever. It silenced Einstein ( unfortunately he could not witness the proof of which came after 60's).

I love the simplicity of the argument used. It wasn't new to me but it never ceased to be awesome and amazing.

How abbout the violations of Bell’s inequalities and entanglement?!

Well, I have just posted a comment on randomness on your simulated universe video. Basically, the concepts are conflicting because as randomness cannot be simulated, we cannot be in a simulation. So if randomness really exists, we are not living in a simulation. As quantum mecanic is random, we may be saved :)
