# The Theory of Relativity

Most of what we know about space (at least in the modern sense) is due in large part to Albert Einstein’s Theory of Relativity. Relativity comes in two parts: Special and General Relativity. Special Relativity deals with objects moving at a constant speed (no acceleration). General Relativity deals with objects that are accelerating. Regardless of the type of relativity you enjoy learning about, both are remarkable and, at some times, completely bizarre.

The Special Theory of Relativity:

In fact, the math used is no more difficult than high school algebra. However, just because the math is easy to understand, it does not mean that Special Relativity should be taken lightly. It is a monumental scientific achievement.

The General Theory of Relativity:

http://www.pbs.org/wgbh/nova/einstein/relativity – This link deals with Relativity and its relation to the universe. There are some great animations demonstrating the physics of Relativity.

Einstein and his Accomplishments:
