The Albert Einstein's Special Theory of Relativity results from two
statements, the two basic psostulates of special relativity:
\begin{itemize}
   \item The speed of light is the same for all observers, no matter what
   their relative speeds.
   \item The laws of physic are the same in any inertial (that is, non
   accelerated) frame of reference.
\end{itemize}
Given these two statements, Einstein showed how definitions of
momentum and energy must be refined and how quantities such as length
and time must change from one observer to another in order to get
consistent results for physical quantities such as particle half-life.
To decide whether his postulates are a correct theory of nature,
physicists test whether the predictions of Einstein's theory match
observations. Indeed many such tests have been made -- and the answers
Einstein gave are right every time!
