Physics is related to experiments. If we cannot even do an experiment in the unobservable universe, why should we talk about the physics there? I think it will only be a philosophical question then.

Shanker's Principles of Quantum Mechanics is quite good and I learned it by myself. Griffiths' book is also very good. Laudau's book is much more difficult and I think it is not easy to read.
