   If a spaceship travels to a planet one light-year (as measured in the Earth's   
   rest frame) away from Earth at high speed, the time taken to reach that planet   
   could be less than one year as measured by the traveller's clock (although it   
   will always be more    
   than one year as measured by a clock on Earth). The value obtained by dividing   
   the distance traveled, as determined in the Earth's frame, by the time taken,   
   measured by the traveller's clock, is known as a proper speed or a proper   
   velocity. There is no    
   limit on the value of a proper speed as a proper speed does not represent a   
   speed measured in a single inertial frame. A light signal that left the Earth   
   at the same time as the traveller would always get to the destination before   
   the traveller. The    
   traveler will not measure her or his speed as being higher than the speed of   
   light, but will see a length contraction of the universe in her or his   
   direction of travel   
   vp can “exceed” c,  r / t/   
   vp = r/{t(1 – [v/c]2) ½ }   
   vp = v/(1 – [v/c]2) ½
