I'm not sure about that analogy but to make clear what I was trying to illustrate: when you put things (matter) on the panyo (spacetime), it folds (gravity). When you do that, other things (matter) get pulled (gravitational pull) towards the thing (matter) because the panyo (spacetime) is now in the shape of a slope.

In other words, with enough gravity, you can bend spacetime enough that time-travel is possible.
