Perceived rate of time |
In relativity, the perceived rate at which time passes is identical for
everyone as far as I understand it, but the amount of time which passes can
be different. If this perceived 'speed of time' where changing (say slowing
down as space is expanding) could we detect this?

The amount of time which passes, with respect to a specified observer's
clock, can be different.

Nope. Our perceptions, biochemistry, measuring instruments, and
everything else moves with time. The universe as a whole could be
bouncing forward and backward through time like a yo-yo and we wouldn't
know it. We can only measure a difference in time rates, like
gravitational redshifting.

All the individual clocks are percieving exactly the same rate of flow of
time, regardless of their relative positions. Could we detect if the rate
of flow is changing relative to yourself?
