I don't see how the bending of spacetime can be a proper way of explaining to people gravity.
Why would bending of space-time imply movement?, (or acceleration.)
The analogy with a ball on a bed sheet can only go so far. (which isn't very far.)
Is this lame analogy used only because, there aren't really any analogies that can be used?
The ball on a bed sheet means there is some other forces that pull objects along with spacetime in some other dimension. Because I've never heard of that, I assume its not true, which makes me wonder why people use that analogy.
(I word things loosely, try to know what I mean please.)
