Comment on 'Frozen time in hyperbolic spacetime motion'
  We show that the conclusion in version 3 of the paper 'Frozen time in hyperbolic spacetime motion' that time does not move in a spaceship undergoing hyperbolic motion is wrong because of a trivial error in interpreting the distance and time variables used in the paper, and because it now incorrectly states that "Hyperbolic motion does not imply constant acceleration."
