The speed of light is constant relative to the universe - whether that is shrinking or growing in "real terms" but I think I might have an answer as to why this must be the case but I am seriously confusing myself:
If we assume energy is constant (safe?) and E=mc^2 then if c is getting smaller in "real" terms m must be getting bigger to balance the equation, surely?
On the other hand if we look at Neuton's gravitational equation:
F = G(m1+m2)/r^2
If the "real" distance is shrinking and the masses increasing then unless the force is getting larger G cannot be constant.
I think? My brain exploded about 20 minutes ago.
