I get objects bend the space around them. I have been told two things: these dents are attractive, and that they are not.
If they are not attractive, shouldn't objects slow down when they come near an object?
Think about an ant walking over a surface with a dent in in. The surface is 2d, but the dent is in 3d. If you look at it from the top, the ant will slow down (and change direction) over the dent.

The distance and time are both longer, but from the second dimension, the distance is the same, so it slows down.
Also, if the bending of space causes the change in direction, what causes things to fall when we release them from a height?
If they are attractive, wouldn't gravity propagate from a higher dimension?
