QUANTUM COMPONENTS. “To a modern relativity theorist, mass and energy don’t exist independently, and these ideas are replaced by a single thing called mass-energy. Similarly, space and time are discarded as independent entities, and are replaced by one thing called spacetime. Spacetime does not consist of space and time, it is one indivisible thing which replaces them both.”
