What scientific evidence exists for the Big Bang Theory?
assistant
The Big Bang Theory is widely accepted in modern science. It is supported by a variety of scientific evidence, such as the observations of the redshift of distant galaxies and the cosmic microwave background radiation. Studies of the relative abundances of light elements created in the Big Bang have also provided evidence for the theory. Finally, the discovery of gravitational waves, which are predicted by general relativity, has bolstered the case for the Big Bang.
