Space battles
So a lot of sci fi these days involve space battles in which multiple ships fire on one another. Of course the questionable science of the Praxis effect comes up (there's neither oxygen nor sound in the vacuum of space; an explosion would not look like the Death Star's death or the original Praxis explosion from Trek). But I have another question.
An object in motion will remain in motion unless acted on by an opposing force. In the vacuum of space there is no friction and, depending on where the object in question is, the effect of gravity from planetary/astral bodies is fairly negligible. Mostly in sci fi space battles happen outside of orbit. So what happens to the shots that miss. Maybe Captain Kirk fired a photon torpedo at a cloaked Klingon ship and didn't land a hit. Maybe Darth Vader missed when he fired at Luke Skywalker as they flew through space in the vicinity of Yavin IV.
So what happened to those shots. Do these bolts of energy keep flying through space at constant velocity, forever??? Are their trajectories somehow recorded and plotted, so space bound ships from various planets can avoid them?? Who records this data in the heat of battle? Is it made public on a universe wide scale. How is that data transmitted freely in times of interplanetary war? How long is this information maintained??? What if Poe Dameron is flying somewhere in the galaxy after retirement and is hit by a bolt fired by Obi Wan Kenobi at the start of the clone wars.
