What does Hubble's constant measure?
Hubble's constant corresponds with distance. Hubble's constant can be measured by velocity (km/s divided by distance (Mpc). It is part of an equation that measures the velocity of celestial bodies rushing away from earth.
The velocity is measured by:
v = velocity in kilometers per second (
d = distance in mega parsec (Mpc)
For example if a typical galaxy is at a distance of 100Mpc, it would be rushing away at 7000
