Einstein proved (w/ relativity):

* There is no absolute distance
* There is no absolute time
* There is no absolute velocity including "at rest"
* There is no absolute mass

However there is absolute acceleration (which is key to General Relativity). But what is cool is how it also shows even the fundamental forces arent absolute. A magnetic field arrises from an electric field due to relativity and vice versa. Very little is absolute but some things are, so cool...
