There is motion in spacetime. Everything that moves through space automatically moves through spacetime.
However consider the comment in the discussion section; yes, it might be said that there is no motion in space time IF you no longer define motion as movement in space per unit time. In that way everything just is, and nothing moves.

Gravity is a force, not a bend in spacetime.
Look at this websitewww.spacetimemodel.com It says that mass is really just a 4d volume of spacetime displacing and therefore warping the spacetime around it and so the answer is all mass displaces and so warps spacetime.

There is no such thing as gravitational force. Mass curves spacetime and stuff moves through spacetime in straight spacetime paths. The effect of this is what we call gravity. The more the mass the greater the curvature of spacetime.
Time doesn't affect space. Space and time are the same thing in relativity; that's why we call it spacetime. Mass affects spacetime and spacetime affects mass.
Physics is a branch of science. It deals with the physical world. It is a natural science that deals with the study of matter and its motion through spacetime, as well as all applicable concepts, such as energy and force
According to the general theory of relativity, gravity does not attract; instead gravity bends spacetime. Objects always follow locally straight lines of motion, but in bent spacetime a locally straight line of motion is not globally straight, instead it is globally bent. Thus it does not matter if an object passing near a black hole has mass or not, its path will bend toward the black hole. Note: do not confuse mass and weight. In free fall all objects, whether they have mass or not, have no weight.
Gravity deforms spacetime, and photons follow the curves in spacetime that are put there by objects with large mass (and, therefore, large gravity).
