I was wondering if I could get a critique of the following pseudo-physics to explain why my sci-fi story includes dogfights in space. I don't want to totally ignore the impossible physics, but I'm looking for something simple. No hardcore sci-fi fan is ever going to buy it anyway. And, yes, it's intended to be somewhat tongue-in-cheek. Thanks, Dirk. Andrew asked, How come you’re able to bank without spinning out of control? There’s no gravity or atmosphere up here? The entire outer surface of the fighter is coated in hypermatter, Joseph said. It’s an exotic element that provides resistance in a vacuum comparable to the effects of atmospheric flight. A little like flying through mud. It allows ships to bank, pitch, and yaw almost as if they were in the air. No one knows why it works, but it makes for great dogfights. Is it related to hyperspace? No. Hyperspace is totally different and was discovered first. Then, whatever nut invented hypermatter probably just thought the name sounded cool.
