What evidence supports the Big Bang theory of universe origin?

Correct option is B

The correct answer is: (b) Redshift of galaxies
Explanation:
· The observation that light from distant galaxies is redshifted shows that galaxies are moving away from us, indicating the universe is expanding.
· This expansion supports the Big Bang theory as the origin of the universe.
Information Booster:
· Proposed by Georges Lemaître in 1927, later supported by Edwin Hubble’s observations.
· Cosmic Microwave Background Radiation (CMBR) discovered in 1965 gave further proof.
· The universe began around 13.8 billion years ago.
· Redshift is explained by the Doppler effect in astronomy.
· Hubble’s law states: greater the distance of a galaxy, faster it recedes.
Additional Knowledge:
· Sunspot cycles: Related to solar activity, not universe origin.
· Solar wind: Stream of charged particles from the Sun, unrelated to Big Bang.
· Volcanic eruption on Earth: A geological event, not cosmic evidence.
