Explain Einstein's Theory of Relativity to me.

Einstein's Theory of Relativity states that the laws of physics are the same for all non-accelerating observers, no matter how fast they are moving. This means objects in motion experience time at a slower rate than that of objects at rest, and the faster one travels, the slower the time. This idea of relativity also explains how gravity works, demonstrating that massive objects cause space-time to curve, thus creating the force of gravity. Other conclusions from this theory involve the equivalence of energy and mass as well as the mass-energy equation.
