State and explain Hubbles Law?

Solution

Step 1. Statement of Hubbles Law

  1. Hubble’s law states that the distance to a galaxy is proportional to its recession velocity. Mathematically, this can be stated as
  2. The Hubble’s law is not only evidence of the expansion of the universe, but also an important explanation to the big bang model.

Step 2. Mathematical explanation of Hubbles Law

v=H0d

v=Recession velocity in km per second

H0=Hubble constant

d= Distance in Mpc

The Hubble effect shows the direct correlation between the earth's distance to a galaxy and its recessional velocity. Thus, numerically, Hubble’s law can be written as

vr

where v represents the recessional velocity in km/s and r represents the distance of the galaxy in Mpc
