So Let's have some Fun

Now of course, the time travel issues are always quite endearing, because good thinking minds can come up with a imaginative way to travel. What stories are these, that are created?

So maybe you have some "ole or new," that you would like to add to the list?

So we know too, that these versions were based on some "historical view" that came from the basis of math? Who is this, that derived and made room for such issues to materialize so imaginatively?

Welcome to the companion Web site to the NOVA program "Time Travel," originally broadcast on October 12, 1999. In the program, leading physicists delve into the mystery of whether time travel is possible, and if so, how one might go about building a time machine. Here's what you'll find online:

So let's go back in time a bit.

Abstract
The gravitational field due to the circulating flow of electromagnetic radiation of a unidirectional ring laser is found by solving the linearized Einstein field equations at any interior point of the laser ring. The general relativistic spin equations are then used to study the behavior of a massive spinning neutral particle at the center of the ring laser. It is found that the particle exhibits the phenomenon known as inertial frame-dragging. q2000 Elsevier Science B.V. All rights reserved.

Van Stokum cylinder by David Darling

A time machine based on an immense cylinder spinning at near-light speed. The physicist W. J. van Stokum realized in 1937 that such an object would effectively stir spacetime as if it were treacle, dragging it along as the cylinder turned. What van Stokum didn't realize is that circumnavigating such a cylinder can lead to closed time-like paths. Anyone orbiting the cylinder in the direction of the spin would be caught in the current and, from the perspective of a distant observer, exceed the speed of light and thus travel back in time. Circling the cylinder in the other direction with just the right trajectory would project the subject into the future. The van Stokum time machine is based on the Lense-Thiring effect and uses ordinary matter but of enormous density - many orders of magnitude greater than that of nuclear matter.

And some general comments:

The century-old dream of time travel remains one of our greatest control fantasies—irrational and irresistible, supremely conducive to megalomania, born of morbid curiosity and mortal dread. Barring the odd literary anachronism (Rip Van Winkle's big-sleep displacement, the Connecticut Yankee's Camelot stopover), it wasn't until 1895, when H.G. Wells unveiled The Time Machine, that the concept crystallized in the public consciousness, spanning nuts-and-bolts mechanics to abstruse metaphysics.
