We were talking about are own scientific theories and his was that gravity didn't "exist" just that matter has the urge to clump or be together. I thought it was interesting but what is your take on it?

He is actually sorta right. More accurately gravity is a ficticious force. In clasical physics the force due to gravity can be calculated by the equation F=MmG/r^2. However, Einstien theorised (and was later confirmed) that light is also attracted to mass (even though light has no mass) and if it passes near mass its direction of motion can be bent. A good analogy is if you were to put a bowling ball on a trampoline and then roll a marble past the bowling ball it would curve around the ball and then keep going straight. In this case the bowling ball represents a large mass, the marble represents a particle, and the trampoline being stretched represents space being stretched.

There is a gravitational force between two different object.
Hope that helps.
