I seem to hear this alot. Gravity does not accelerate an object, gravity bends space-time so the objects merely follow curved paths. Then they give an analogy, usually a bowling ball on a mattress. I dont understand the above. How can an object that is not moving follow a curved path? An object cant be driven by geometry alone. I might point out that, a bowling ball, on a mattress away from gravity, wont move at all. What does he literally mean?
