The idea of GR was, that gravity is actually an effect of 'curvature',

What gets curved is actually the 'axis of time' local to a certain part

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

type space.

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

Curving the (imaginary) axis of time cannot curve real space since space
is not a surface.

Relativity needs 3D space to curve without a surface to bend the path of
light 2x Newtonian. It cannot accomplish that because space is not a
surface, and spacetime cannot curve space. What you are calling space is
spacetime.
