Quick question:
Assuming that the expansion of our universe DOES cause time to accelerate, does this mean that life within our universe is shorter, or longer? I.E., if two men lived to be 80, man A living in the 18th century and man B living in the 21st century, who has lived a longer life? Do both men live the same amount of time, or does time acceleration cause man B's life to go by faster?
Just something i was pondering today.
If this is in the wrong section, please excuse, and mods feel free to move..

Expansion of space is creating distance inbetween the galaxies. Creating distance is not motion and won't effect time. Therefore time everywhere in the universe is runing at a near fastest rate outside of gravity's slowdown.

Ohh, thanks for your reply Nicholas! Other comments?
So universal expansion in no way effects time here on earth?

No we live in the near fastest time. Einstein's General and Special Relativity are about the Two ways time slows down from this fastest point; those are gravity and high speed motion which requires an acceleration.

So when you say near fastest speed, that means in no way can time, or anything else, get faster?

Right. The limit for everything is C or the speed of light. You could associate a kind of speed of time with the speed of light.
I have had a strange thought that time might get faster in the future. If it did we couldn't tell just as when your clock slows down you cannot tell of your own frame. You would have to look out at other clocks to see that yours has changed.

Ooh i get it. I remember in '04 there was some internet hype about some new theory about universal expansion causing time rates to accelerate or something. There was actually an article published about it, ill have to get the link for it

It looks like if time can slow it get faster!

If time were to get faster, how much faster would it be from the reference point of Earth?

It can't be noticed. All time rates have a proper time in experience. No matter the speed of your clock you cannot observe is to get slower or faster. It is undetectable just like steady motion through invisible space.
The speed up would have to happen universally.

Well yeah i know that, but i mean what would be the rate of change? For instance, 10x faster, 20x faster..
