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. Is homogeneous and isotropic.
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.
