My understanding was 'measuring is touching' with light, imparting energy into the delicate system, and no measurement can be done at that scale (thanks to the rules of light frequency/energy) that can both detect it and be weak enough to not bother the result.

So when I say like the double slit needs to be adapted, it would need to account for such. It would need to test for 'choice' from a particle... somehow...

Or... maybe randomness as a concept is flawed. Maybe randomness === '(some level of informed?) choice' from particles we are not privy too. not some 'hidden variable' but a dynamic ability to 'choose'?

How would we prove random is random and not a choice/decision we can't see or understand?
