    The main difference between swimming and flying is basically just how compressible the fluid you’re moving through is, so it’s not that different really. Although I guess you can fly through space so my attempt to sound clever kind of falls through, huh?

      Just look at the compression in 3D (resistance to existing motion) instead of just in an up/down 2D plane and your analogy still works, even in space.

      you’re mostly right !

      you can fly through space, but not like a bird flies through air or sharks swim in water; “swimming” in space is way weirder.

      I can’t find it, but there’s a video on PBS Space Time where they talk about how that could work
