JUMP TO LIGHTSPEED!!!!!!!!!!
The basics of space travel in Star Wars require huge amounts of handwaving for it to work. This will haver real science considerations but I'll warn you, this will fall on the soft sci-fi spectrum of things. First, jumping to light speed is not enough to travel around the galaxy. Just for comparison, the closest star system to ours is 4.37 light-years away. Even if we don't know the distance between planets in the movies, it would be odd to have a galaxy with a cluster of extremely close star systems. But assuming that you can jump to light speed, ignoring any relativistic side-effects for now, it can be extremely useful. Travel between planets in the same star system would take minutes and it would make Poe Dameron's "lightskipping" make sense in Rise of Skywalker. Whatever is the tracking system that they use to track each other (radar, sight, whatever), the signal of the sensor picks up travels at light speed at max. So short bursts of light speed would b
