According to our current understanding of physics, it is not possible for an object to move exclusively through time without any movement in space. In our everyday experience, objects move in both space and time. This is described by the concept of spacetime, where the four dimensions—three spatial dimensions (length, width, and height) and one temporal dimension (time)—are interconnected.
In the theory of special relativity, developed by Albert Einstein, the concept of spacetime is crucial. It states that the motion of an object in space affects its motion through time and vice versa. Objects that are at rest in space (not moving in relation to their surroundings) are still moving through time. This is because the passage of time is a fundamental aspect of our universe, and every object experiences it.
To clarify, when we talk about movement through time, we refer to the changing of events or moments occurring for an object. It's important to note that this movement through time is inherently tied to an object's motion in space.
So, in short, every object is constantly moving through time, even if it appears to be stationary in space. There are no known examples of objects that move exclusively through time without any spatial movement.
