When spacetime is not bent the two objects, red ball and blue ball, will move strait up the y-axis as they move through time. (Space is x and time is y).
Now I've made the assumption that either a) All things want to move the smallest possible distance to the next point in time or b) all objects move 90 degrees relative to the rotation (Curvature) of the space in their coordinates. These two assumptions give the same result. As you can see in the picture below the blue ball is now heavy and has curved space significantly. Where the red ball is the time is now pointing a bit to the left. As the two objects move through time they will now meet in one point.
Is this what gravity is or have I missunderstood it? If not I'd be really glad if someone could show me a 2d picture of spacetime and how it actually works.
