Is time travel possible in Newtonian curved spacetime?
Newtonian curved spacetime is just another formalism for standard force-based Newtonian gravity. So I don’t see how, unless the spacetime has some non-trivial topologyaccdd said:Is time travel possible in Newtonian curved spacetime?
According to Newtonian physics, time is considered an absolute and linear dimension. This means that time travel, as commonly depicted in science fiction, is not possible in this framework. However, there are some theories that suggest that it may be possible to manipulate time through gravitational effects.
In Newtonian physics, gravity is described as a force that acts between masses. This means that a massive object, such as a planet or star, can bend the fabric of spacetime. This bending of spacetime can potentially create a "shortcut" through space, allowing for the possibility of time travel.
Currently, there is no experimental evidence to support the idea of time travel in Newtonian spacetime. However, some scientists have proposed theoretical experiments that could potentially test the feasibility of time travel through gravitational effects.
One major limitation of time travel in Newtonian spacetime is the concept of causality. This means that events must occur in a logical and chronological order. If time travel were possible, it could potentially create paradoxes and disrupt the fabric of reality.
The theory of relativity, developed by Albert Einstein, revolutionized our understanding of time and space. In this framework, time is not absolute and can be affected by factors such as gravity and velocity. This means that time travel may be more feasible in the realm of relativity rather than Newtonian physics.
