How Does Relativity Work?

What is general relativity? Essentially, it's a theory of gravity

. The basic idea is that instead of being an invisible force that attracts objects to one another, gravity is a curving or warping of space. The more massive an object, the more it warps the space around it.

How do you explain relativity to a child?

1. The principle of relativity: The laws of physics are the same for any inertial reference frame. 2. The principle of the speed of light: The speed of light in a vacuum is the same for all observers, regardless of their relative motion or the motion of the source of the light.

How does relativity affect time?

In the Special Theory of Relativity, Einstein determined that time is relative—in other words, the rate at which time passes depends on your frame of reference. ... The faster a clock moves, the slower time passes according to someone in a different frame of reference.
