Since the "Big Bang", the fabric of Spacetime has "stretched", so much so, that the resulting expansion of the universe could be called the "Big Stretch" (Carroll & Ostlie. Intro. Mod. Astrophys.). Now, when any physical object stretches, it thins out. Thus, the fabric of Spacetime could (conceivably) have been "thicker", in the perpendicular Hyperspace "w" dimension, back when the universe was younger. Now, Variable Speed-of-Light Theories posit that the Speed of Light was significantly swifter in the early universe. Thus, it could (conceivably) be the case, that the Speed of Light is faster in "thicker" Spacetime.

 

 

It seems to be said, fairly often, that "gravitationally bound objects experience no expansion of spacetime". For example, the incessant "stretching" of Spacetime does not "rip apart" our Solar System, nor our Galaxy, nor our Local Group. So, once a "glob" of matter becomes "gravity bound", the Spacetime it occupies (apparently) stops "stretching", and "freezes out" of the background Hubble Expansion.

 

If so, perhaps archaic bound objects, like the early dwarf proto-galaxies (which were ~1% the mass of current galaxies) which formed in the first billion years of the Cosmos' existence, managed to "lock in" and "preserve" their local Spacetime fabric, in its original "un-stretched state" -- in particular, with its original & greater "hyperspace thickness" ??

 

Indeed! In my theories, the "Big Bang" is simply an illusion due to this expansion.
