Newton's laws of motion describe the relationship between the motion of an object and the forces acting upon it. However, they do not provide any direct information or equations regarding time travel. Time travel is a concept that is currently speculative and hypothetical in nature, and it goes beyond the scope of Newtonian physics.
The idea of time travel often involves theories from the realm of theoretical physics, such as general relativity and quantum mechanics. These theories propose various concepts and possibilities for time travel, including the concept of manipulating spacetime curvature, creating wormholes, or utilizing advanced technologies that are purely speculative at this point.
It's important to note that time travel is still largely a subject of scientific and philosophical debate, and there is no consensus on its feasibility or the specific mechanisms that would be required. Therefore, it is not possible to determine how many Newtons or any specific quantity of force would be needed for time travel based on our current understanding of physics.
