As a few may have noticed, I've been watching Voyager episodes lately, and someone brought this to my attention. They say that Voyager is over 70,000 light years from the Alpha Quadrant, and Voyager is a vessel capable of sustained flight at Warp 9.975 (which is over 21,000 times the speed of light, or a light year every 25 minutes). So with that said, shouldn't the flight of Voyager back to the Alpha Quadrant take between 3 and 4 years, instead of 70 years like we're told?
