No Cable,the expansion rate is relative to gravity.Gravity slows time down
Space is thinner in a low gravity field,so time passes faster,relatively.
This is by,implication,not uniform across the universe.the 'independant'
observer would see the passage of time as universal,but that is the
observers evaluation within the time frame the observer is in.Change
the gravity field the observer is in,and change the perception of the
observer,Galaxies do not expand,gravity holds the whole thing together.
The space between galaxies expands because the matter it contains
is so diffuse as to present no resistance to the expansion.Gravity does.
