Question

Is there true randomness in the universe?

In: 80

Answer 1

We don’t know.

Let’s first think define true random. True random would be given an input we could in no way figure out the output no matter how much information we have. This would be the opposite of pseudo-random where we could figure out the output given enough information. What computers do is pseudo-random. Whenever a random number is generated, it’s based on a key and if you knew the key, you could figure out what “random” value would be produced.

Currently, we don’t know the key. Maybe the universe has one and maybe it doesn’t.
