<human>:  Explain the theory of relativity in plain language.
<bot>: The Theory of Relativity is a scientific theory developed by Albert Einstein that explains how gravity works and why it affects the way we perceive time and space. In brief, relativity suggests that time and space are relative to the observer and that the speed of light is constant regardless of the observer's movement. It states that the laws of physics are the same in all inertial frames of reference, and that the speed of light is the same regardless of the speed of the observer or the strength of the gravitational field. This means that, for example, two observers moving at different speeds with respect to one another will measure different times for the same event, and that the same laws of physics apply in all frames of reference. The theory also suggests that gravity is a result of the warping of space and time by matter. In layman's terms, this means that gravity is the result of energy and mass deflecting and redirecting other objects in its vicinity.
