Answer 2

ANSWER:-

• B. the observation that galaxies are moving away from each other. is the correct option.

• The observation that galaxies are moving away from each other was used as evidence to develop the big bang theory and the origin of the universe.

EXPLANATION:-

The Law of Hubble enabled astronomers for calculating how long ago galaxies commenced moving apart from each other, which provided an estimation of when the Big Bang developed and the age or origin of the Universe.

• Hubble originally underestimated distances to these isolated galaxies so he evaluated that the Universe was nearly 2 billion years old. Geologists instantly criticized the findings of Hubble because they had quantities that showed the Earth to be around between 3 and 5 billion years old.

• The Universe couldn’t probably be younger than the stars and planets in it and this issue was resolved in the 1950s when contemporary information showed that the Universe was between 10 and 20 billion years old. In recent, the best estimate is that it’s 13.7 billion years old.
