Discover the origins of the universe with the Big Bang Theory, its evidence, and its implications.

108 views

The Big Bang Theory suggests that the universe originated from an extremely hot and dense singularity approximately 13.8 billion years ago. This singularity then expanded rapidly, leading to its current state. Key evidence includes the cosmic microwave background radiation and the redshift of distant galaxies, which supports the idea that the universe is still expanding. This theory helps explain the formation of galaxies, stars, and other cosmic structures.
