The big bang theory states that the Universe began by expanding from a small point nearly 14 billion years ago. Since that time, the Universe has continued to expand, and it is still expanding today.

In 1964, two scientists, Arno Penzias and Robert Wilson, were studying electromagnetic radiation emitted from space. During their research, they detected background radiation coming from all directions in the sky. This background radiation was found to be microwaves created during the big bang.
