The distance is always positive, so it should be |p1-p2|, |s1-s2|, |g1-g2| instead of (p1-p2), etc.
I agree, was wondering whether to use such symbols, not sure of reading age to target.
speed[]
The name "speed" is deceptive IMNSHO. The reason it contributes to travel time by its square root is that it's actually the maximum scalar acceleration value.
This makes sense for space travel since there's no "fixed" reference frame by which to measure speed. Galaxies, stars, and planets are all moving at different velocities relative to one another.

Non-looping[]
Does this mean that the longest travel time in the same galaxy will be from System 1 to system 499 (and back)?
By Loop, I thought that 0 would be just as close to -1 as it was to 1. Not infinately far away.
So I'm guessing that system 1 is closer to the black hole or whatever nearest to the center of the galaxy and 499 would be near the edge?
