Official Description

The three most important postulates of the Special Theory of Relativity of Albert Einstein applied visually and interactively.
By varying the speed of an object and the duration of the trip, we see the various postulates are met:
- Length contraction
- Time dilation
- Increase of the rest mass (energy)

This application is not a game, but a didactic way to understand the equations that make up the theory. Very useful for students of Physics.
It lets put exact values of speed and time as well as accuracy.
