I have a doubt that in Albert Einstein s theory it is there If a spaceship that is going at the 5 0 speed of light so the person in the space ship feels that for everyone time is very fast so if the spaceship goes to 99 at speed of I ight so the time for everyone will be even mo re faster and finaly the spaceship goes at th e speed of light so the time for everyone will stop so my question is why this happens and why the spaceship not stops as the time for t he people will stop and in 99 of speed of lig ht the time for people will faster and why not in the speed of light that happens
