reverse time travel can be achieved without having to travel faster than the speed of light

The rotating cylinder model is based on a conclusion of general relativity that shows rotation of matter causes a distortion in space-time. This distortion can become powerful enough to actually twist time around a rotating cylinder.

With the right amount of mass and speed, a pattern of what are referred to as “closed time-like curves” can be created.

Navigating through this pattern of closed time-like curves will permit time travel to both the future and the past without violating the laws of mathematics and physics.

To understand time control using rotating cylinders requires some understanding of general relativity. An overview of the “General Theory of Relativity” has been included as a separate article in this issue of The Space-Time Journal. It also requires a basic understanding of space-time physics, including the ideas of space-time diagrams, light-cones and closed time-like curves. Following is a brief review of these topics>

Space-Time Diagrams

A common tool we use to discuss space-time is the space-time diagram. This diagram plots the position of a particle as it moves through space-time. By connecting all the plotted positions, a line called the “world line” of the particle is created.

In reality, a true space-time diagram would have four dimensions including three space dimensions and one time dimension. This type of diagram is very difficult to illustrate and visualize. Wherever possible we use a simpler convention to illustrate concepts in space-time.


The illustrat


The illustration shows a simplified space-time diagram with just one space axis (y) representing motion through one space dimension, and one time axis (t) representing motion through time.


Lets look at the example of a particle starting at rest on the origin of the y and t axes. If the particle does not move over time in the space dimension (y) it will not move off the time axis (t).

So for a particle at rest in some observers’ frame of reference, its space-time diagram for that observer is a vertical world line. This is illustrated in the space-time diagram to the right showing a particle at rest.
The path the particle follows, whether it moves in the space dimension (y), time dimension (t), or both represents what we call its world line. The world line represents the path the particle follows in space-time as a whole.

If the particle moves in the space dimension (y), its world line tilts away from the vertical as is illustrated in the space-time diagram of a particle moving at constant speed shown to the left. Straight (un-curved) world lines like this represent un-accelerated particles (i.e.) particles experiencing no forces.

If a particle experiences acceleration, its world line will curve away from the vertical time axis. If the same particle experiences decceleration, its world line will curve back towards the vertical time axis.

The resulting world line will be curved as is illustrated in the space-time diagram of an accelerating/deccelerating particle on the left.

In order to make a space-diagram more meaningful in has become common practice to normalize the axis to a specific standard.

Each unit on the time axis (t) is set to a second and each unit on the space axis (y) is set to one light-second. A light-second is the distance that light can travel in one second, which is 300,000 kilometers. This normalization of axes is illustrated to the left.

Is this a tutorial on space-time diagrams? Im not sure where you show 'reverse time travel' without going faster than the speed of light. Im kind of slow, so can you point it out and try to explain it? Also what of causality?

Sounds like frame dragging as theorized by Einstein in General Relativity.  If so, nothing new... if we can somehow figure out a way to line up a bunch of neutron stars, and then spin them really fast...  :rolleyes:

"To do right is to know what you want. Now when you are dissatisfied with yourself it's because you are after something you don't really want. What objects are you proposing to yourself? Are they the objects you really value? If they are not, you are cheating yourself. I don't meant that if you chose to pursue the objects you most value, you will attain them; of course not. Your experience will tell you that. But success in getting after much labor what you really don't care for is the bitterest and most ridiculous failure." -George Santayana
