 * The theory of relativity is still proven to be true and and is used in society today. **




 * In Einstein’s theory of relativity, he proved the speed of light is constant in space and also in inertial, all physics laws are the same. In other words, Einstein proved that time changes depending on your reference location. His most famous formula, E=MC^2 is commonly known throughout the world and refers to relations between mass and energy. So when a change in mass occurs, a change in energy results too. Also, another relationship proven by Einstein was the idea that acceleration and gravitation are equal and therefore when in the same reference frame it is observed equally. **

Einstein's theory of mass-energy relation is evident in society. His knowledge that when mass is lost it gives off energy (Relativity) is used today. Our nuclear power plants use the idea of change in mass to create energy in today's world. Nuclear fission is a great supply of energy, although it has its bad effects, the benefits outweigh the negatives. This is one part of Einstein's theory of relativity that is evident in today's world.



Einstein is quite well known around the world for many of his theories, and is known by many. One miraculous discovery was that gravity is equivalent to acceleration. Therefore, gravity can also effect time and space. So one can always feel gravity in the opposite motion that one is traveling. Overall, Einstein's theories are impressed upon us routinely (NOVA).

Another field Einstein contributed to was astrophysics. He theorized that when a star's gravity is so strong, it sucks all the light and communication in forming a black hole. It is when a stars collapses that their light cannot withstand the gravitational pull forming the hole. This was an amazing find of Einstein and contributed greatly to the world of astronomy and understanding of star cycles (NOVA).

Einstein's theory changed our ways of thinking and took a new turn in the physics world. It was the beginning of imagination being used in the world of science. His theory of relativity led us to observe time, space, mass, and energy differently. He also came up with more efficient ways for energy. Overall Einstein's theory of relativity has allowed us to progress into the future of science.

Lightman, Alan. "Einstein's Big Idea." __NOVA.__ 1 June 2005. PBS. 1 Jan. 20 .

The author believes that Einstein made some great discoveries. He expresses different parts of the theory in clear words and gives examples to make it easy to understand. The expressions used follow the content of the Relativity Theory and is very informative.
