What is the big bang theory?

• A theory that states that the universe started in a large mass and then imploded to form everything.

• A theory that states that the universe was there, will be and is there.

• A theory that states that the universe is slowly coming back to a center.

• A theory that states that the universe started in a small mass and then expanded, the expansion cooled down the temperature and that resulted in the formation of matter, energy, space and time.
