has gravity have anything to do with friction
Friction in Space. Yes, when two surfaces rub together in outer space, there will be friction. Friction is a surface effect and doesn't depend upon there being air. There is also a force like air resistance from the very sparse gas in space, but it will be very, very small, since space is a very good vacuum.he density of matter in our Galaxy is about 1 particle/cm3 (in the disk, with the halo being less dense). The density of matter in intergalactic space (between galaxies) is about 2 x 10-31 gm/cm3, mainly hydrogen. At these densities, I don't think one has to worry about friction.
