special relativity -if you are travelling inside a train that is going at a constant speed, you do not know whether it is travelling or at rest...(of course without looking outside of the window)...usually we replace train with the term 'inertial frame of reference' where it means it is travelling in a uniform velocity or at rest...

ok, this is the principal <---- i think
and if you understand the principal, read Jacaranda pg 85 where it talks bout light travelling inside a train where it is travelling at the speed of 'c'. And either side of the train is a door that opens as soon as light hits on it. According to the theory, the person inside the train will see both door open, but an outside observer will only see the backdoor open...
