Varying G Vs Cosmic Acceleration

The Gravitational Field of a uniform spherical mass M is a product of volumetric acceleration G [(m^3/sec^-2)/kgm] multiplied by M. Over time, the volmetric acceleration of the Hubble sphere diminishes as 1/R (R being the radius of the Hubble Sphere) whereas the increasing size of the Hubble Sphere extends the field of M. In consequence, the measured inertia of M is increasing in proportion to R, so the MG product remains constant. This is why attempts to measure changes in G by orbital tracking always produce a null result.

A diminishing G and increasing M could, however, explain why distant 1a supernovas appear to be less bright - the event involved less energy because it resulted from less mass compressed by a higher G factor.

The premise of Ia supernova's as standard candles may be entirely incorrect. Because the apparent brightness of the more distant events appear dimmer than expected, the data has lead to a theory that the universe is accelerating - but this result can also be regarded as evidence that the gravitational constant is not constant.

A higher gravitational Constant in the past also explains another cosmological puzzle - how galatic formation took place so quickly in the early universe?
