Scaling physics SEEMS to work correctly the minute we stop scaling the
weight as well. I'm sure the concept of why this makes sense is super
simple but it alludes me at the moment. No matter, it seems to work,
so I'll leave it be for now and check back later when I have other
things to check besides just the ship...
