This post is a collection of 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
Accelerating feels like a force, while moving at a steady speed does not
To an observer, an object moving near the speed of light appears to contract in length
To an observer, an object moving near the speed of light feels heavier
When an observer is moving near the speed of light, the rest of the universe contracts in length
When an observer ismoving 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
