Lets say we have a ship 100 meters long with one person up front and one in the back, call it a 100 meter long hallway. Let us say it has attained a speed within a centimeter of the speed of light per second. Let us say that each person heads to the front or back of the ship. Wouldn't the one heading to the back of the ship have no problem getting there, while the one heading to the front be limited to a speed no more than one centimeter per second? It is said that all things would seem normal to a person approaching the speed of light, but how can it be normal for the dude in the back of the ship? This person would expect to see things like as if he were traveling at walking speed as he heads to the front of this ship, but that speed is not possible.
