I was inspired by Phoenix-06's work, so I decided to try my own exploding planet with "Project Athena's Spear" - part of my friend's and mine paralell multiverse. Just to explain, Athena's Spear is an orbital gun, 6 by 16 miles. It fires a projectile escaping relativistic speed, using a network called "subspace" to travel 800 times light speed. However, subspace is only meant for small particles - communication, and it normally does not interact with normal space. An exception is with Athena's Spear, whose projectile creates an ionic plasma wake en route to it's target - the blue trail.
