FANTASTIC TRAVEL TIMES

Travel times at relativistic speeds are generally easy to calculate. Simply determine how long it takes to arrive at the destination while traveling at the speed of light, then divide the result by the light speed multiplier of the drive being used. Some sample travel times appear in Table: Fantastic Travel Times.
