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.
| Relativity theory that explains Lorentz contraction and time dilation for observers in relative motion. | E = mc2 (where m is mass, E is energy and c is the speed of light) | Lorentz contraction and time dilation | Einstein (1905) | | relativity theory |
