Question

10. How was Hubble able to calculate a rough estimate for the formation of the Universe?
A. By calculating the rate at which the Universe is expanding
B. By calculating the rate at which the Universe is shrinking
C. By calculating the age of the oldest atoms
D. By calculating when hydrogen was first formed​

Answer 1

It was Edwin Hubble's seminal 1929 PNAS paper, “A relation between distance and radial velocity among extra-galactic nebulae” (1), that led to a turning point in our understanding of the universe. The graph reveals a linear relation between galaxy velocity (v) and its distance (d)v=Ho×d.

Answer 2

• Edwin Powell Hubble was an American astronomer.
• He was the one who played the important role in the field of extra-galactic astronomy.
• He explains the formation of universe as by the form of expanding ,age etc.
• This theory was explained in 1929.
• It takes place at the event named BIG BANG.
• It states that galaxies are moving away from our own at a great speed in all directions.

• Hence,The Hubble was able to calculate a rough estimate for the formation of the universe by calculating the rate at which the universe is expanding.
