We recently touched base with gravity in regards to general relativity and I'm a bit perplexed. So apparently (and correct me if I'm wrong) gravity is created when the mass of the universe warps, or bends, space-time. I've read all those analogies about a trampoline curving due to an object of mass, but (here's where I'm confused) doesn't a trampoline or blanket anything bend because of the presence of gravity? How can the warping of space-time cause gravity if gravity is the one causing the warping?
