Just a query(space time and evolution):
If time runs very fast things will disappear. similarly if time runs slow or very slow things will be stationary(w.r.t what i don't know). But time is uniform at present. I don't know, on what factors does it depend. May be some Gravitational forces between galaxies or matters trying to confine these things together and may affect time and evolution of the system also. One thing that i believe(rationally) is that if forces in matters will decrease system will evolve fast(can't say about time variation).
