A Theory on Time Travel (and Time Traps)

I will try and hijack the original purpose of this image for my demonstration.

Question. Do humans time travel when they do actions that have no impact on the present and of which they will only benefit from in the future? During those actions, they actually live in the time frame those actions (will) have effect?

Let's say we have two objects, A and B with comparable masses and sizes, in an isolated system. Let's say object A is moving frictionless or with very little friction at a determined speed and direction. Then a human may intervene and place the object B in front of object A. There will be no more interactions between objects or human and objects until the time of collision, which will happen on a predetermined moment in the future. By placing, by an intelligent being, the object B in front of object A at a certain point on object's A trajectory, the path and trajectory of the object A will be changed in a predictable way, at a certain moment in the future, by an action done in the present or past with no further interactions in between those moments. More than that, at the time of collision, the path of object A it is altered by an action done in the past by the human (on object B).
