What is Cosmic Inflation?

Cosmic inflation is also known as the Inflation Theory which says that shortly after the universe came into existence, it expanded very rapidly. This relates directly to the Big Bang Theory. From nothing, or singularity, an explosion occurred, and from that point, all matter expanded - or like a balloon, inflated and is still moving away from the original point of creation. Imagine dropping a stone or rock in the middle of a very calm lake - from the point where the rock entered the water, you get a round ring, or wave, moving away from the center. However, in the universe, there are no boundaries to stop this expansion outward. This is cosmic inflation.
