462 views

The Big Bang theory is centered around the idea that the universe began as a singular, infinitely dense point roughly 13.8 billion years ago. It then rapidly expanded and continues to expand today. Key points include the cosmic microwave background radiation as residual heat from the initial explosion, redshift of galaxies indicating their movement away from us, and the abundance of light elements like hydrogen and helium that support the theory.
