Of the 2 compatible explanations, I really like the many worlds theory over hidden variables. Many worlds explains this unexplainable randomness, the probabilistic nature of subatomic particle movements, by saying all possible movements happen…. The probabilities just indicate the likelihood that our reality is the one that movement X happens in.

And then you throw the block universe in, and it’s just all the more beautiful.

All possible combinations of atomic interactions all happen. Well “happen” is so linear time thinking, they all just exist.
