It has recently struck me that despite my interest in both physics (as a qualified physicist) and philosophy (as a complete amateur), I have not encountered any philosophy regarding the 'origin' of the universe or indeed aspects of the Cosmos as a whole. While metaphysics is increasingly dealing with questions and dilemmas in modern theoretical physics, I have not seen anyone address the question of *why* the Universe/Cosmos exists.
I raise this point purely from a metaphysical standpoint. (The religious aspect is irrelevant.) I am curious whether most philosophers would even think it is a valid question to ask *why* the Universe exists. That is, why not nothing? (I do not mean the Universe is a limited physical sense, as part of a great "Multiverse" perhaps, bus as the all-encompassing everything.) If it does not sound too strange: why does nothing not exist? The temporal problems that some consider; for example the "beginning" and "end" of time do not particularly bother me as a scientist, since time...
