Since until there was restrictions on mass, but only on radius for light, think under big mass G can begin to decrease. Situation is hypothetical.

Light doesn't slow from C while leaving gravity therefore it doesn't have an escape velocity like matter does. Mitch Raemsch

Electrons can never reach c,but in the Fermi accelerator going at 99.999999999 of c they weigh 70,000 times their rest mass. All this Einstein told us when he was 26 TreBert
