Can anyone explain the theory of relativity to me?
Without going into a lot scientific mumbo jumbo, Einstein’s theory of relativity states that nothing in the universe is ‘absolute’. Your perception of anything (e.g. size, speed, position, and even passage of time) is relative to how you are moving. In short, your measurements for size, speed, position and time, will be different from another person who is travelling at a different speed to you. The differences are neglible at low speeds but can vary dramatically when dealing with speeds approaching the speed of light. The speed at which we see light moving is the one thing which is the same for everybody. No matter how fast you are moving (relative to someone else) you will record the same speed of light – roughly 186,000 mile sper second.
