The Big Bang Theory

Explanation

What is the Big Bang Theory?

The Big Bang Theory is a theory of how the universe was created 10-20 billion years ago.

Evidence of the Theory

1. Galaxies appear to moving away from us at a proportional distance from the center of the universe.

2. Since the explosion was so hot it left a remnant of heat called the Cosmic Microwave Background that scientists discovered.

3.The abundance of light elements hydrogen and helium support the Big Bang Theory Model origins.

What Happened?

At one time all matter was compressed into one tiny sphere smaller than a ping-pong ball. Then a huge explosion happened creating our universe we know now. Our universe is still expanding at a proportional rate.
