general relativity			Gravitation is a curvature in four-dimensional space-time rather than as a force existing between two masses.	gravity	special relativity	twistor theory	four-dimensional structure of space-time	Einstein (1915)	Einstein's theory of gravity
special relativity	A spaceship (or other enclosed vessel) traveling at uniform speed through space contains its own space-time continuum. A ray of light passes an observer at the speed of light no matter how (uniformly) fast nor in what direction the observer is travelling.	E = mc2 (where m is mass, E is energy and c is the speed of light)	Relativity theory that explains Lorentz contraction and time dilation for observers in relative motion.	Lorentz contraction and time dilation				Einstein (1905)
