Solid evidence for true randomness in in the universe?

[Mazuz]

Again you say that I’m speculating. I always speculate, but not in this very simple argument.

there's nothing that we know of that indicates that there's anything beyond QM

Maybe, except that to say that there is no theory that unites the universe more comprehensively is also speculation. Regardless.. a partial description of the universe, without speculating, can’t speak for the universe as a whole.

I've done experimental measurements on it, see others doing measurements of it, and observe results that simply have no classical analogue!

This is true, however is relative to a theory which does not fully describe nature.

I do not take experimental verification like this very lightly.

Nor do I. I do not dismiss the results, they are real. But to interpret what they mean is not the role of QM.

We are not going anywhere with this argument. I understand your position. You are very intelligent and far more knowledgeable than myself on these matters, I respect your opinion. To sum it up you think QM demonstrates evidence for a truly random universe without speculating, I do not.

I think we can agree on a different question. Is the universe truly random? We don’t know (nor do we know whether the universe is deterministic or not). If we elaborate on this I believe we will end up each repeating ourselves.

Hi Chronos, I truly respect your thoughts and wisdom, but I'm not sure you have been following this conversation.

Golly, I thought determinism had passed on to that big theoretical scrap heap in the sky about 2 centuries ago.

Perhaps it has, I don’t claim otherwise nor is my argument for determinism.

Randomness dominates the macroscopic universe and it does not seem unreasonable to suspect that it's turtles all the way down

No it does not seem unreasonable, nonetheless this is speculation.

Perhaps some things appear to be random because they really are random

Yes, perhaps.

When all observations have suggested randomness at the atom level, and none have have been contradictory, it is enough to convince me of a claimed fact. Physics is based on observation, and it concludes randomness at the atom level without any contradiction yet. Until someone observes a contradiction, randomness has to stay, and such has been the state of physics for the last 75 years.

Everyone is invited of course to do an experiment demonstrating determinism at the atomic level. A speculation is a hyothesis, that's the first step of the scientific procedure. Everyone knows the rest since they were 10 years old, but 6 000 000 000 people have had 75 years to follow through and still nothing.
