john ur not quite right they were saying that you wold run out of fuel
im saying that no matter how much fuel current rockets have speed limitiation based on the speed at which they exhaust gases
u r all missing the point the reason why we cannot move at this speed
a rocket can only accelerate at the same speed as the gases it exhausts
our current fuel powered rockets only expel gases at 20 000km/hr
u ppl take this way to serious it was just a hypothetical
it takes longer from the outside frame of reference not on the ship there is no canceling out that occurs
also as the ship is accelerating there is no need for an outside frame of reference
