Our universe is about 14 billion years old. The most common theory of how the universe started is the Big Bang theory. This theory is most commonly accepted because it has the most evidence to support it. Some of this evidence can be listed here: the abundance of the "light elements" Hydrogen and Helium are found abundantly in the universe., background radiation has still been found in the solar system, and the fact that galaxies are still moving away at speeds proportional to their distance. The universe contains many characteristics such as:
-It is estimated that the Universe is 156 billion (156,000,000,000) light years across.
-consists of approximately 100 billion galaxies
-the Earth and planets in our Solar System are part of the Milky Way galaxy
-turbulence of the explosion resulted in the spinning of the galaxies
- the shape is said to be curved
