The Age of the Universe
Knowing the current
rate of expansion of the universe, we can estimate the time it took
for galaxies to move as far apart as they are today:
T ≈ d/v = 1/H ~ 14 billion years
Time = distance / velocity
velocity = (Hubble
constant) * distance
Light we see today left
this galaxy when the universe was only ~ 1 billion years
old!
