gollark: There would be significant legal issues and also quite likely damage to the box.
gollark: Maybe you would be better off using quantum field theory. Except that doesn't have gravity/general relativity, only special relativity, so you should work out how to unify those?
gollark: We can just say in the technical and artistic merit video that "the robot's projectile trajectory handling maths has relativistic corrections in it and would thus be equipped to fire projectiles near the speed of light, if we actually needed that, had a way to accelerate things that fast, could do so without destroying everything, did not have interactions with the air to worry about, and could safely ignore quantum effects".
gollark: If you really want to you can apply special relativity, sure.
gollark: I don't *think* we need to consider air resistance significantly.
