Quantum cosmology is a field attempting to study the effect of quantum mechanics on the formation of the universe, especially just after the Big Bang. Despite many attempts, such as the Wheeler-deWitt equation this area of interest has yet to be fruitful.
Quantum cosmology is a branch of quantum gravity.
the quantum theory
It was Copernicus's theory and Galileo had very little evidence for it at the time of his quarrel with the Vatican, as he discovered when they put him on trial and asked for the evidence.
The 'big bang' theory.
not only is it possible but no experiment has ever been done that contradicts it in any way. it has been shown correct in its predictions to more digits than any other theory.
While that is an interesting theory, there is simply no evidence to suggest it is true... so No.

Not sure what you mean by "derive" quantum theory; that's along the lines of "deriving" gravity. In our Universe, quantum theory is the only one we've developed that matches experimental evidence. In all cases, quantum theory was developed mathematically simply because no other explanation existed that would match what occurs in our Universe. Whether we like it or not, whether we really understand it or not, we are in a Universe that obeys quantum theory.

Quantum theory has been tested and theoretical and experimental values have been found to agree to more digits of precision than in any other theory tested against reality!

Quantum theory is being explored in neurological research to understand how quantum processes at the cellular level may influence brain function and consciousness. Some scientists suggest that quantum effects could be involved in phenomena such as synaptic plasticity and information processing in the brain. However, this area of research is still speculative and controversial, and more evidence is needed to establish a solid connection between quantum theory and neurological phenomena.
The theory of cosmology that Copernicus proposed is called the heliocentric theory. This theory placed the Sun, rather than the Earth, at the center of the solar system, with the planets orbiting around it.
