Question
Hubble was able to calculate a rough estimate for the formation of the Universe by_____________.
- Calculating the rate at which the Universe is decreasing.
- Calculating when hydrogen was first created.
- Calculating the rate of the expansion of universe.
- Calculating the age of the chlorine atom
Hint:
According to him the universe was expanding.
The correct answer is: Calculating the rate of the expansion of universe.
- Edwin Powell Hubble is an American astronomer. He played an important role in the field of extragalactic astronomy.
- He explains the origin of the universe in terms of its expansion shape, age, etc.
- This theory was explained in his 1929. It takes place in an event called the Big Bang.
- It states that the galaxy moving at high speed in all directions.
- Hubble was therefore able to calculate an approximation of how the universe formed by calculating the rate at which it is expanding.
- So the correct option is c.
