In fact, I would go much further than that: science cannot prove the non-existence of anything at all. All scientists can do is to support positive statements with circumstantial evidence (Lakatos 1974), or disprove them by refutation (Popper 1968). So, we are left with the rather unsatisfactory position that science throws a little bit of light in the abyss of the unknown, but not enough to answer perhaps the most important philosophical question of them all: is there something beyond matter and energy?
