What is the Big Bang?
Question asked by: knowitall
This is the hypothetical explosion that occured at the origin of the universe. The title Big Bang was actually used in a derisive manner to mock the theory, but it actually stuck!
At the time, the universe was superdense. It exploded under the pressure of itself, and threw material outwards like the biggest bomb ever. The cause of it is unknown and it is also not known if this event actually occured, though evidence to date is compatible with the theory and there is background radiation that is currently put down as remnants of the explosion.
Under the theory the universe went from being the size of a pea before the Big Bang (if our current dimensions have any meaning in the context of before a Big Bang) to the universe we know today over time after the Big Bang.
