Aristotle and science So the cosmological argument was mentioned. Matter is able to be explained according to material laws. If an aspect of eternal time and infinite space, both of which can be in various ways, is accepted the cosmological argument is not necessary as a proof. In fact, calling objects hybrids of form and prime matter most nicely sets up a system within which relativity and quantum mechanics can exist side by side. Nor does time have to be infinite, but could have existed in a finite loop as it was creating with the first motion of matter following the laws of gravity. Einstein and Hawking each had a theory as to how the cosmological argument fails and any appeals to the contingency of the world is going beyond science and into unfounded philosophy. The universe is contingent and necessary at different times in that it changes from substance to flux, always following the laws of matter-energy equivalence. There is no need for non-material energy in the world
