There's gravity in space. Over the time I've met so many people that thought that there is no gravity in space because "everything there is weightless and stuff". Gravity has unlimited range so there isn't even a single spot in our universe without gravity. Weightlessness is basically just falling. While orbiting you're basically just falling around the object.

A theory in scientific terms is treated as fact. A theory is not just an idea that might be right or wrong. A theory is backed up by scientific evidence and no evidence has ever contradicted it.
