In 1919 Albert Einstein became famous for his theory of Relativity. It all began on a night when a solar eclipse appeared. This was one of the first theories of gravity since Newton's 3 laws. 1905 was when Einstein first developed this Theory of Special Relativity. Einstein proposed that the theory was based on things near or at the speedof light. He helped us lead to new insight about the structure at creation of the universe.

The theory of relativity affects our society in many different way involving branches of physics as well as in cosmology.

-Black holes are very common in space and this thoery helps to show us what would happen if someone was to shine a light beam on a black hole. 1. The light would approach the center but you specifically would approach the center even quicker. 2. An outgoing light beam that is shined on a black hole will move away from the person at exactly the speed of light. - No matter what space-time may be an obsever will only see the light beams in one direction at the same speed. The black hole example explains with the theory of relativity that nothing moves faster then light.(Felder)

__**Particles**__ -Einstein's thoery is still affecting us today in certain particles - Some particles have a clock that is calles "intrinsic", they determine the decay process of the particle. -The rate that a clock ticks in a frame that is in motion observed by a stationary person is slower than the rate of a static clock. -The decay process for moving particles for a stationary observer is increased by the factor gamma From this example we can see that with the help of Einstein's theory we can determine things so hard to beleive such as half life particles (Theory: Special Relativity (SLAC VVC))

__**Cosmology**__ Cosmology is the study of the whole universe - It helps us to know that the distance between each star will eventually shrink or even expand -We now know specifice information about our universe If it was not for Einstein's theory of relativity we would not know we had an expanding universe. (Felder)

In conclusion without Einstein's theory of Relativity we would have very different perspectives. We would not be able to have some of the technologies we have today that help each and every one of us. This theory that Einstein discovered is continuing to change our world because of the other theories that came from it. Also I think it can still help us to improve our deception of time and help with the use of technology.
