Question

What does Hubble's law as discussed in Toolbox 16-1, Discovering the Universe, 10th edition, give for the distance at which the recessional speed of an object equals the speed of light?

Answer 1

Answer:

4225 megaparsec                        

Explanation:

             Recessional speed of an heavenly object can be defined as the speed or velocity with which the object is moving away from the earth. The recessional speed of any cosmological object at a certain distance is also called as Hubble velocity.

            Hubble's Law describes the expansions of our universe and the galaxy.

            According to Hubble's Law, 5224 Mpc is the distance at which the speed of light becomes equal to the recessional speed.

Therefore, the answer is --- 4225 Mpc
