**Elbert Einstein first introduced the theory of relativity was in 1905. Einstein experiment of theory of relativity played off of Newton’s theory of motion. it does not make what newton's work wrong. Einstein's work is well known as the correct description of motion and relativity objects."Einstein's predictions may seem strange. However, many years of high energy physics experiments have thoroughly tested Einstein's theory and shown that it fits all results to date."( special relativity) "Note that this is quite different from the motion of ordinary, massive objects. If I am driving down the freeway at 50 miles per hour relative to the road, a car traveling in the same direction at 55 mph has a speed of only 5 mph relative to me, while a car coming in the opposite direction at 55 mph approaches me at a rate of 105 mph. Their speed relative to me depends on my motion as well as on theirs." (special relativity)**  The equation //E=MC2// shows how to convert between energy units and mass units. this equation will help you through out life when unavailing energy. this is a very important equation. " This tells us the energy corresponding to a mass m at rest. What this means is that when mass disappears, for example in a nuclear fission process, this amount of energy must appear in some other form. It also tells us the total energy of a particle of mass m sitting at rest. Einstein also showed that the correct relativistic expression for the energy of a particle of mass m with momentum //p// is //E2 = m2c4 + p2c2//. This is a key equation for any real particle, giving the relationship between its energy (//E)//, momentum ( //p)//, and its rest mass (//m)//. If we substitute the equation for p into the equation for //E// above, with a little algebra, we get //E = gamma MC2//, so energy is gamma times rest energy. (Notice again that if we call the quantity //M =gamma m// the mass of the particle then //E = MC2// applies for any particle, but remember, particle physicists don't do that.)" (special relativity) "For example, let's look at a particle sometimes created at SLAC known as a tau. In the frame of reference where the tau particle is at rest, its lifetime is known to be approximately 3.05 x 10-13 s. To calculate how far it travels before decaying, we could try to use the familiar equation distance equals speed times time. It travels so close to the speed of light that we can use //c// = 3x108 m/sec for the speed of the particle. (As we will see below, the speed of light in a vacuum is the highest speed attainable.) If you do the calculation you find the distance traveled should be 9.15 x 10-5 meters. //d// = //v// //t// //d// = (3 x 108 m/sec)( 3.05 x 10-13 s) = 9.15 x 10-5 m" (special relativity) work cited Chopping, Peter T. .

 * Theory of relativity is an interesting concept but it can be very confusing, the three things that are important about this topic is the equation for energy is E=MC2. Energy and mass are interchangeable, and d=v* t.**
