What we call 'space' has a certain (geometric) relation to the axis of

Curvature of the axis of time is actually an acceleration in a

Now this can 'curve' and we get gravity, which is a force, that results

TH

it is good to hear someone here who can plainly explain relativity so
everyone can understand. The only problem is that space is not a
surface, so it can't curve. Non-Euclidean geometry cannot curve space,
so it can't cause gravity. The idea that the concept of curved space is
somehow an improvement over the idea of fields of force is mistaken
because it involves the elementary error of reification fallacy.
