This structure contains infinite mathematical models that we can define as limits of infinite converging sequences of finite models which realize successive approximations more and more precize, in the same way we can define real numbers as limits of converging sequences of rational numbers.
We can virtually consider that any mathematical model generates a universe, but this universe really exists only if it contains spirit that perceives it. According to the fundamental metaphysical principle, every infinite mathematical model generates spirit perceiving this model as an external reality constituting the physical universe in which this spirit lives.
The existence of an infinity of mathematical models yields to the existence of an infinity of universes. Each of these universes, including of course our universe, would then be the materialization of a mathematical model, or rather what we perceive as a materialization, because in fact everything would be only relationship between mathematical beings.
We will now examine the consequences of this hypothesis of mathematical universes, trying to answer to some metaphysical interrogations at the light of this hypothesis.
This hypothesis of mathematical universes gives a new lighting on the non-determinism of quantum physics when the wave function collapses and about the many worlds hypothesis.
