This post is a list of fundamental principles of relativity. There are 10 principles listed below.
- Time feels the same for all observers
- Nothing can move faster than the speed of light (670,616,629 miles per hour)
- The speed of light is the same for all observers (670,616,629 miles per hour)
- Accelerating feels like a force, while moving at a steady speed does not
- To an outside observer, an object moving near the speed of light appears to contract in length
- To an observer moving near the speed of light, the rest of the universe contracts in length
- To an outside observer, an object moving near the speed of light feels heavier
- To an observer moving near the speed of light, the rest of the universe feels lighter
- An object moving near the speed of light moves through time slowly
- Massive objects cause time to go slower in the space around them
