14 billion years ago the Big Bang began, it was a cosmic explosion. The Big Bang is the origin of space and time itself. Everything in the universe is made from matter. Our Big Bang is just one of many Big Bangs said by scientists. The first real evidence of the Big Bang was that Edwin Hubble discovered that galaxies were not stuck in one place they are moving away from earth very fast. Hubble said that the universe is expanding and that it started from a single point. The first force that came out of the Big Bang was gravity. Gravity shaped the universe. The universe expanded faster than the speed of light, which is called plank time. The particles of the universe were moving around like crazy and as it expanded the particles slowed down.
