The Universe is a wonderful toy.

According to the late Dr. Robert Forward, if one rotates a massive object (or stream of objects) around a toroidal field (as shown in the illustration at the bottom left of your post), one will produce a gravitomagnetic field (i.e., artificial gravity) about the torus (shown in blue in the illustration).. A object encountering this field will be accelerated without inertial effects along the field lines (shown in red in the illustration) with a velocity proportional to the strength of the field.

In other words, if you built such a torus out in space, you could "drop" a ship into its vicinity and the artificial gravity field around the torus would "kick" the ship out into space at an arbitrailty high speed — and without subjecting the passengers to any g-forces whatsoever.

Thanks for an interesting post.

Re above post: for “bottom left” read “bottom right”. Sorry for the dysgraphia.

Trippy. So maybe that why flying saucers have maintained that form-factor for the over 2,500 years that they have been observed. They've hit the bottom of physics, and must employ such a toroidal system internally.

Just guessing. I really have no idea. Pretty cool to think about, though.

The more we learn, the more we realize we don't know.
