Einstein’s Theory of Relativity Albert Einstein’s theories of relativity changed what we originally believed about the physics of our world, and also added new dimensions to our understanding of physics. Einstein combined two previous theories: the Theories of General Relativity and Special Relativity, to create his Theory of Relativity. This theory changed our ideas of how to do rational science. It also added to the basis of modern quantum mechanics by stating that light really comes in little bundles of energy called quanta.
What Are These Theories? The General Theory of Relativity demonstrates that time is related or linked to matter and space (AllAboutScience). For example, a period of time for someone on Earth that lasts for hundreds of years might only be a couple of hours for someone speeding around in a rocket at nearly the speed of light (IFLScience). Another example is the …show more content…

One consequence was relative simultaneity, two event, simultaneous for one observer, may not be simultaneous for another observer if the observer is in motion. The relativity of simultaneity is closely related to the constancy of the speed of light. For example, imagine two trains, A and B, moving relatively at half of the speed of light. A flash bulb is triggered in the exact center of one of the A-train cars. Since the speed of light is the same in all directions to the A-observer, the light strikes the ends of the car, which are 10 m away from the center, at the same instant in the A-frame. However, to the B-observer, the A-car moves forward so that its front wall moves away from the moving light signal and its back wall moves toward the light. Since the speed of light to B is unaffected by the relative motion of A, the light hits the back wall before it strikes the front wall. Another consequence is length contraction. Objects are measured to be shortened in the direction they’re moving with respect to the
