There is an idea that if the Universe is closed then its total energy is zero and both space and time are emergent (one from entanglement and the other from a superposition of all possible configurations of the Universe). The Universe as a static wave function. What do you think?

I would add that "why is there something rather than nothing" might not be a good question to ask, because you're including any possible answer in the question itself - you can't reference an answer since you're including everything in the question.

In the case of a wave function from which space and time can emerge you can't ask for an answer other than the abstract nature of the laws of physics and math, which don't need any creator and don't have a beginning, they just "are" - there's no way you can "destroy" them or prevent them from existing.

This is my favorite answer.

What do you think about the black hole information loss paradox? There was word some time ago that it was solved. On the other hand, Penrose bases his Conformal Cyclic Cosmology on the fact that information is actually lost in the black hole and it's a proposed mechanism for getting the entropy back down for a new Big Bang in the future.

What's your take on this idea and Conformal Cyclic Cosmology in general? My own personal take is that Higgs field fluctuations could get rid of mass in the future such that there's no particle with mass to measure space and time and fulfill Penrose's take.
