**Albert Einstein is best known for creating the Theory of Relativity in the early 20th century. So what's the Theory of Relativity mean, the theory that space and time are relative concepts rather than absolute concepts. You're probable thinking what does this is even mean. Albert Einstein theory is the most simplest terms mean, that time and space can be bend by mass. The bending in space causes the mass to move. The theory of relativity breaks down into two subcategories. Special Theory of Relativity and General Theory of Relativity. Special theory of relativity, no matter how fast or slow the observers are the speed of light is the same to all. General theory of relativity, an object that is in motion.** 

Relativity, theory, developed in the early 20th century, which originally attempted to account for certain anomalies in the concept of relative motion, but which in its ramifications has developed into one of the most important basic concepts in physical science The theory of relativity, developed primarily by German American physicist Albert Einstein, is the basis for later demonstration by physicists of the essential unity of matter and energy, of space and time, and of the forces of gravity and acceleration.(Lawrence A. Borntstein)

Here are some example : the twin pardox- one of the twins stay on earth, while the other travels in space. when the other twin comes back he or she will be younging then the twin on earth, why because for the twin on earth time really passed and the uter space twin experienced less time

speed and distance traveled were dependent on the frame of reference of the observer. For example, if you are on a train and you roll a ball in the same direction the train is moving at a speed of 5 feet per second, you will observe the ball moving 5 feet in one second. Suppose however that the train is moving down the tracks at 10 feet per second. A person standing next to the tracks will observe the ball moving at 15 feet per second and traveling 15 feet in the same one second. So who's right? The both are, but from their own frame of reference. ( [|www.**thebigview.com**/spacetime/ **relativity**.html] )

General theory of relativity, an object that is in motion. one of an example that work would be the twin pardox- one of the twins stay on earth, while the other travels in space. when the other twin comes back he or she will be younging then the twin on earth, why because for the twin on earth time really passed and the uter space twin experienced less time.


 * Work site:**
 * Some things that people can find out are when the theory was developed. also the general laws before the development of the theory of relativity. including the different types of theory the writer is Lawrence A. Bornstein, M.S., Ph.D. He is a professor at the department of physics at the New York university. Also th author of a contemporary view of elementary physics and calculus of the physical sciences.**
