<human>:  Explain the basics of Albert Einstein's Theory of Relativity.
<bot>: Albert Einstein's Theory of Relativity is one of the most renowned scientific theories ever. It is based on the concept of special relativity and general relativity. Special relativity states that the laws of physics are the same for all observers regardless of their relative motion, and that the speed of light is the same in all inertial frames of reference. General relativity is an extension of special relativity, and states that the space-time aesthetic of the universe is curved due to the effect of gravity. This is known as the ‘curvature of spacetime’ and explains the gravitational effects seen in everyday life. Together, these two theories explain gravitational phenomena, like how stars move, how light interacts with matter, and the way objects move when accelerated. It is also used to explain things like dark matter and dark energy.
