Well, I don’t have much confidence in the parallel timelines (multiuniverse existance) theory of time. It makes much better sense to consider time a property of motion in the 4th dimension (axis).

But if time is indeed a 4th dimension then it is always difficult to convert that into a visual model that our brains can understand.

What if time is a property of gravity… where you fall through time at a constant rate relative to the gravity. Problem with this is that time would pass at different rates on different planets (which hasn’t been proven either way).

If you imagine yourself, and everything else on Earth, falling through time. Then Newton’s laws of motion would apply to time. If an object is falling through time it will continue falling until a force stops it. The force required to stop it (or accelerate it) is proportional to the velocity and mass. And there must be an equal and opposite reaction to motion through time.

Using this (fictional) model how would you stop someone from falling through time, or accelerate them away from it (back in time)?

You would need to understand the properties of the time-force, whether it is related to gravity fields, whether it is related directly to mass, or space.

Also this would delete the notion of parallel timelines. If one object were to be pushed into an acceleration away from the time force, then they would no longer exist in their previous position in relation to everything else that is falling. Once they are placed in a location behind the previous, and began to fall again at a constant rate. Would they, or not, be in the past? Would familiar objects be seen around? ..existing in a previous time? Becuase you have to visualize it as another plane of existance. so the other dimensions would be connected to it.

Like i said, its very hard to visualize the 4 dimensional properties. But perhaps the “falling” model will help.
