That's where you're wrong geoguy, gravity DOES vary with altitude. If you fing yourself falling into a black hole, you would experience a stronger pull on your feet than your head. thus, you get ripped apart. Stars near black holes expirience the same thing. If gravity did not weaken with range, EVERYTHING in the universe would be sucked into black holes, which would then be dragged into each other into a single point along with the VERY FABRIC OF SPACE AND TIME>
