Time Travel in Newtonian Spacetime: Is it Possible?

In summary, according to Newtonian physics, time travel is not possible as time is considered to be absolute and unchangeable. Additionally, the speed of light is the fastest possible speed that an object can travel, making faster-than-light travel impossible. Newtonian physics also does not allow for backwards time travel due to the concept of causality. There are potential paradoxes associated with time travel in Newtonian spacetime, such as the grandfather paradox. In contrast, Einstein's theory of relativity allows for the possibility of time travel as time is relative and can be affected by factors such as gravity and velocity.

Newtonian space is Euclidean and Newtonian time is absolute.

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 topology

1. Can we really travel through time in Newtonian 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.

2. How does gravity play a role in time travel in Newtonian spacetime?

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.

3. Are there any experiments or evidence to support the idea of time travel in Newtonian spacetime?

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.

4. Are there any limitations or constraints to time travel in Newtonian spacetime?

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.

5. How does the concept of relativity affect time travel in Newtonian spacetime?

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.
