Question on time dialation

  1. Oct 14, 2009 #1
    If you where going to use a ship to go 99.999999% of the speed of light, for one hour of non dilated time, how much fuel would you carry? enough to keep your ship going for the amount of dilated time or non dilated time.
    (sorry for the badly worded question.)

    Do you mean the energy necessary to accelerate a ship from 0 to 99.999999% the speed of light relative to its starting frame? That will, of course, depend upon the mass of the ship. But you also talk about "keep the ship going". It requires NO energy to keep something moving, without friction, at a constant speed no matter what that speed is.
