Yes, that is a key I guess - how would you measure such a thing. For space we can measure the expansion through some means because we can measure distant galaxies, but we cannot measure the time for those distant galaxies - or can we? Would there be some event that takes a known time so that we...

But LOCALLY there is also no expansion. The expansion happens in the large scale (cosmic scale). So the question remains how time expands or contracts or what on the cosmic scale.

I have one question I hope someone here can answer for me. Relativity theory tells us that space and time are sort of the same thing, as a spacetime. So when space is expanding, what happens to time? I find it hard to believe that time is somehow unaffected by the expansion of space, so while...
