In a refined version of Wigner's interpretation of quantum physics, the Universe is explained as a part of the mathematical world (a specific history inside Everett's many-worlds) that is distinguished by the event of being consciously perceived. Physics focuses on the mathematical side of this combination, that is a Platonic mathematical realm slightly less than infinite. Consciousness provides the substance of time and randomness (beyond their mathematical forms as 4th dimension and probability laws).
