If there was an 'aether' or gas filling space, it would have currents in it like any gas, which would cause fluctuations in a gravity field. If space were like an atmosphere things that move through space would slow down from the resistance. Space can have density by which I mean a large volume can be squeezed into a smaller area. The density of a gravity field puts a tight squeeze around a particle of matter. So unlike cutting through an atmosphere, matter moving through space squeezes the space it passes through up against it. A boat on water doesn't do this. The squeezing of denser regions on other regions which cause gravity fields and gravity also keeps an object travelling through space at a constant speed. The outward pull of the universe against the pull of the extremely dense particle of matter balances to create the gravity field. Since the pull of the universe is equal on all sides of the particles gravity field, whichever direction the particle is headed in is a less dense region that is attracted to the density. This doesn't propel the particle however because the pull is equal on all sides, but allows the particle to travel along its path without slowing down.
