I know they do in real life. It's the illustrations showing a static curve that the masses slide over that I'm taking issue with.

- rm445 7y agoOh yeah, I see what you mean. I think the models in the article are deliberately simplified. At least some of those plots demonstrate a constant force, rather than a gravitational-type force. And the well-known weights-on-a-rubber-sheet analogy is notoriously unhelpful. I guess the real equations work for real curved spacetime.
