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.
Analyzing the worldline on a spacetime diagram can provide information about an object's motion, speed, direction, and interactions with other objects in the spacetime.
Geodesic motion is significant in physics because it describes the path that objects follow in curved spacetime, as predicted by Einstein's theory of general relativity. In this context, geodesic motion is the natural motion of objects in the presence of gravity, following the curvature of spacetime caused by massive objects. This concept helps us understand how gravity affects the motion of objects and how spacetime curvature influences the behavior of matter and energy in the universe.
Gravity is a force that acts on objects, pulling them towards each other due to the curvature of spacetime caused by massive objects.
The affine parameter is important in spacetime trajectories because it helps measure the proper time experienced by an object moving through spacetime. It allows for a consistent way to track the path of an object regardless of the coordinate system used, making it a valuable tool in understanding the motion of objects in curved spacetime.
Special relativity, developed by Albert Einstein in 1905, deals with the behavior of objects in uniform motion and the concept of spacetime. General relativity, developed by Einstein in 1915, extends special relativity to include gravity and the curvature of spacetime caused by mass and energy. In essence, special relativity focuses on objects in motion, while general relativity incorporates gravity and the curvature of spacetime.
Time and space are interconnected according to the theory of relativity. Time can affect space by bending it, creating what we know as gravitational effects. The presence of mass or energy can bend and warp spacetime, influencing the motion of objects within it.
Special relativity deals with the behavior of objects in uniform motion and the concept of spacetime, while general relativity extends this to include gravity and the curvature of spacetime due to mass and energy.
The curvature of spacetime, as described by general relativity, influences the trajectory of Earth's orbit around the Sun by causing the path of the Earth to follow a curved trajectory around the Sun. This curvature is due to the mass of the Sun bending the fabric of spacetime, which in turn affects the motion of objects like the Earth that are moving through this curved spacetime.

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.
