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.

That is true if evern photons passing through the event horizon can't
go faster than c They must be the very bluest of all photons.
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

Space expansion need not obey SR It could go faster than c I know

That's totally nonsensical, but even so, how would that limit
acceleration?
