The time of change is equivalent to the change in space, energy, and curvature.
Time, space, energy, and curvature are the manifestations of the motion of objects or masses. Space, whether macroscopic or microscopic, is an axially spinning spherical space. At the center of space, the object with a large mass rotates around its axis, while small mass objects orbit around it. The processes of both spinning and orbital motion are examples of wave motion. The period of the wave always obeys Galileo's law of the simple pendulum period. The space of an object is its gravitational field. The gravitational field of an object is infinite. The direction of gravity is always directed towards the center of the spherical space. Because of this, the curvature direction of the gravitational field of any two objects is always opposite. They are attracting or acting on each other.
