This is a new explanation of the experimental physics of mass, space,
time, gravity, and Big Bang theory. It shows that Einstein's
metaphysical assumptions of equivalence, massless photons, and relative
motion are not necessary to explain the measured dynamics of matter,
energy, gravity and the creation of the universe with a Big Bang. The
principle of the Living Universe describes the evolution of matter and
energy in the Cosmos from its beginning and resolves the many paradoxes
and contradictions in Big Bang theory.
