A spaceship moves near the speed of light. Its time becomes slow for an observer on earth. 1. Does 'time' slow only in and around ( i.e. the space inside and outside) the spaceship? If yes, to what extent ( i.e. how much meters or centimeters) above the physical boundary of spaceship. 2. Suppose, the space ship has something vertically projected from it ( a thin antenna etc.) that reaches a height of 100 km (or even 100000000.......km, just suppose). There is a watch at top of this antenna. a) Would it also slow down? b) Would all the space between bottom to top of this antenna experience slowing of time, as seen by an observer on earth?
