A physicist would call the universe an emergent behavior of quantum theory, but not an epiphenomenum.
The latter implies a lack of causality and I don't know any physicist who credibly believes that. Quantum is still causal in that the universe as it is observed is an emergent and causal outcome of processes which are at their base, non-causal.
We see the same process in biology. Although evolution is blind and random at its base, natural selection leverages the random variations into a very powerful model for how life in the universe operates.
I firmly believe that quantum theory provides the base on which the universe operates. It is non-causal at its base, but the emergent behavior is causal, just like biology.
I think that if one strays far from these principles, one may be wasting ones career. But one never knows.
I wish these people luck, just like I do the String Modelers. Both are long shots. But we all need lots of ideas on the table, even if they seem weird.
And this does have that Time Cube element to it.
thanks for your response.
