Special Relativity

Is there such a thing as absolute time? In other words, does time pass at the same rate for everyone? The answer is that it doesn't. The faster you move the slower it passes.

In everyday life objects obey the laws of mechanics that we are familiar with, i.e. Newton's laws of motion. When objects travel very fast, however, these laws need to be modified.
