What evidence supports the Big Bang theory of universe origin?
Show answer & explanation
Correct answer: B
Explanation
Answer: Redshift of galaxies
Explanation: The Big Bang Theory explains the origin of the universe as an expansion from an extremely hot and dense state. One of its strongest pieces of evidence is the redshift of galaxies.
What is redshift?
When galaxies move away from us, their light shifts toward the red end of the spectrum, indicating that the universe is expanding.
This observation was first supported by Edwin Hubble, leading to Hubble’s Law in cosmology.
Additional Key Facts
Another key evidence is Cosmic Microwave Background Radiation (CMBR)
Universe is estimated to be about 13.8 billion years old
Theory developed in modern form by scientists like Georges Lemaître
Expansion of universe supports the idea that it began from a single point (singularity)
