Lets say we have a space ship traveling at exactly the speed of light, and u decide to walk forward at 5 mph thru the ship...you would be technically breaking the light speed barrier yes?
No...mass cannot travel faster and in order to keep this constant, time itself slows down to barely a crawl to keep you under the speed of light, so yes this is the way relativity works.
Just because we see something does not mean that is occuring to that object.
actually ....
1st we must establish a reference frame from which we can say " this ship is travelling at the speed of light "
once we do this however , we would perceive , from this reference frame , that a clock on board the ship , is not moving ( the second hand never moves , " time " on board the ship never " advances " )
therefore , we are unable to actually perceive anyone , or anything , " move forward on the ship " , as it would seem to be " frozen in time " , from the perspective of a reference frame that perceive's it as moving at light speed
again
always remember that a clock that moves at light speed does not change its " time " ( but rather is considered as " frozen in time " )
once again
if a person was on board a ship , that from a reference frame " a " ,he is travelling at light speed , and that from refernce frame " a " , that ship , and the person on board , can be observed for millions on years ( in fact , an infinate amount of time ) , and absoulty no internal motion would ever be observed ( the person on the ship would not age one second , his heart would not beat even once )
it is in fact impossible to observe a person move , if he is travelling at light speed .....
