So I downloaded the entire Star trek Voyager series, and I have just finished the first episode of the second season. In it Paris says to Amelia Earheart that voyager can travel "warp 9.9, in your terms thats about 4 billion miles per second"
I am a mechanical engineer and could not help myself checking to see if it would actually take you 75 years as is stated at the begining of the series to cross the galaxy.
The milky way is approx 100,000 ly across, at 5.87849981*10^12 miles per ly this is 587,849,981,000,000,000 miles. A truely massive number.
The problem is that at 4 billion miles per second, or 126,144,000,000,000,000 miles per year it would take you only 4.66 YEARS ( not 75 years) to cross the entire diameter of the galaxy.
This seems like a gross miscalculation. Am I missing something?
