**Albert Einstein introduced his theory of Special Relativity in 1905, which helped proved the behavior of matter, energy, and time and space.

Special Relativity was introduced in 1905 by a man named Albert Einstein. His theories explained the behavior of matter, energy and time and space. Theories of relativity made it impossible for people to believe the strange events. The theories of Relativity referrers to two specific theories, General and Special relativity. Special Relativity says that nothing can travel between two points faster than the speed of light. ** **General Relativity is basically the theory of gravitation introduced by Einstein.

Theory of relativity, states that objects will move slower and shorten in length from the point of view of an observer on Earth.(Theory of Relativity) E=mc2 is the famous equation, Einstein created to reveal the equivalence of mass and energy. Einstein developing Special and General relativity proved that Newton's three laws of Motion were correct by breaking down when velocities approached that of light, along with Newton's law of Gravitation breaking down when gravitation became very strong. ** 

Albert Einstein went through a lot of work proving that each and everyone of his theories were correct. It took many experiments to make this happen, but in 1905 he proved his theory of Special Relativity and in 1916 theory of General Relativity. Special Relativity is when no accelerations are involved and its effects become noticeable near the speed of light. On the other hand, General is when accelerations are involved and in the presence of strong gravitational fields.

The famous equation E=mc2 proves that mass and energy were related. This was determined most dramatically to the world when nuclear bombs released the energy of mass in Hiroshima and Nagasaki at the end of World War II. This is when Einstein knew for sure that his theories were correct. However Einsteins theories were not immediately accepted by other physicists, because it seemed so theoretical. This topic was so controversial to everyone around. When he received a Nobel Prize in 1921, it was only for his solution to the photoelectric effect, and for all that he has done for the contributions to Theoretical Physics.

As you can see Albert Einstein was a very busy man during the beginning of the 1900's. With creating and proving different theories, that he thought one day could change the ways of Physics. He accomplished all of his goals he had for his all of his experiments. He created a famous equation that proved mass and energy were related. After all of his hard work proving his theories, many physicists of that time thought that it was to theoretical to be true. They didn't quite believe what his theories were. He then was awarded a Nobel Prize in 1921 but only for his solution to the photoelectric effect and for all that he has done for the contributions to Theoretical Physics.
