graphics about black holes or planets’ influence on gravity, etc., always show these bodies “sitting” on a flat surface and then bending that surface below them. is this a literal representation – ie is there a definitive “down” direction that always dips under the objects’ mass? or does it happen in multiple directions somehow? (or am i misunderstanding something fundamental about this curving?)

Does it only curve in one direction?
As I understand anti-matter produces anti-gravity. Wouldn’t that mean antimatter makes space-time curve in the opposite direction?
