The Big Bang theory is the leading explanation for the origin of the universe. It suggests that the universe began as a singular, extremely hot and dense point about 13.8 billion years ago and has been expanding ever since. The theory was developed through observations of the redshift of galaxies and the cosmic microwave background radiation, indicating that the universe is expanding. Groundbreaking work by scientists such as Georges Lemaître, Edwin Hubble, and others helped formalize this theory.

FAQs & Answers

  1. What evidence supports the Big Bang theory? Evidence includes the redshift of galaxies and cosmic microwave background radiation, which indicate an expanding universe.
