Las evidencias del Big Bang

The video explains the Big Bang theory, supported by three key pieces of evidence: the expansion of the universe, cosmic microwave background radiation, and the abundance of light elements. Edwin Hubble's discovery of redshifted galaxies supports the universe's expansion. Cosmic microwave background radiation, discovered in 1965, is consistent with the Big Bang. The abundance of light elements like hydrogen further supports the theory, making it the most convincing explanation for the universe's origin.

How does the abundance of light elements support the Big Bang theory?

In what way does the Big Bang theory provide a convincing explanation for the origin of the universe?
