Ken,

"Just how much information can fit in one universe anyway? Why should it need an infinity of information just to function? Nothing else seems to."

I dont know, but I'll take a stab at it: What if infinties are compulsory for a universe to be truly open-ended and non-deterministic? It just seems that maybe the universe would not be as complex, dynamic and creative without infinite values. In a weird way infinity is like an automatic driver of creativity because nothing repeats exactly ever and ever.

"There's no evidence that we could. At present, QM appears to do everything that can be done, except when that involves unification with general relativity-- and there's no immediate reason to think that making QM deterministic will allow that unification. Most experts seem to think it will require removing the determinism from general relativity. I cannot say why!"

That interesting because as far as Im aware the classical macroscopic world is as non-determinstic as is the quantum. I dont understand the need to make GR non-determinstic when we can already observe non-deterministic behaviour in nonlinear (non-idealised) open ended systems. I know many dont agree but i think there is a correlation between the HUP at the quantum level, and unpredictability on the macroscopic scale due to unknowable initial conditions. The key factor in both physical laws or principles is exactly the same; it being that total certainty is not possible.

To me GR is covering completely different part of nature's behaviour. I see qm as way more fundamental on the question of determinism/non-determinism than GR but that is just my personal speculation.
