He introduces the Principle of Relativity , which states that the laws of physics are the same for all observers moving at constant speeds, and the fact that the speed of light is constant regardless of motion. This leads to the famous conclusion that time and space are relative and linked as "spacetime". He introduces the Principle of Relativity , which
