Following four different fundamental principles, plus Weinberg's universal relation, we find five reasons that demand that the gravitational masses and the speed of light vary with cosmological time (the masses increase and the speed of light decreases). We prove that this is consistent with Einstein's theory of general relativity. We call this effect a “mass boom,” which is a linear increase of gravitational masses with cosmological time, with a corresponding decrease of the speed of light and the gravitational constant. In the lab system no such time variations can be detected unless we are dealing with cosmological observations (e.g., the redshift). We integrate Einstein's cosmological equations and find the solution for the cosmological scale factor to be a(t) = constant × t2, implying an accelerated expansion for the universe. This is the interpretation given to recent observations obtained from the Supernova Type Ia.
