Answer 2

Answer:

The Big Bang is a scientific theory about how the universe started, and then made the stars and galaxies we see today. The universe began as a very hot, small, and dense superforce (the mix of the four fundamental forces), with no stars, atoms, form, or structure (called a "singularity").
