Evidence that UFO propulsion may use artificial gravity William C. Treurniet, August, 2008
Summary. Some photographs of UFOs show that these objects are often positioned beside subtle toroidal patterns of distortion in light propagation. Other photographs show that light beams are bent in the vicinity of UFOs. These observations suggest that the UFOs' propulsion system generates localized curvilinear gravitational field gradients.
A report of 1954 UFO sightings published at the Fotocat site includes a photograph of the aftermath of a forest fire taken near Anchorage, Alaska. The photo shows an unusual elliptical shape above the trees that likely led to its inclusion in the database. No explanation for the anomaly was offered. The complete image is shown in Figure 1a, while the area of primary interest is shown in Figure 1b.
As indicated above and in the earlier report, UFOs are often found on or near the surface of a torus. Further, analysis of images of the Hutchison effect (see here) showed similar insubstantial tori in regions of space where anti-gravitational effects occurred. If the tori in the two phenomena have similar origins, the UFO would appear to ride an oriented gravitational field gradient to achieve motion. A photo of a UFO caught in a laser light show (see Figure 2) is consistent with this interpretation. Figure 3a shows the UFO cropped from the original image, and Figure 3b shows a contrast-enhanced version of the cropped image. The latter shows that the less intense light beams near the UFO are bent as would be expected in the presence of a curved gravitational field gradient.
The use of artificial gravity for propulsion is not a new idea (see here), although no successful technology yet exists in the public domain. A flying machine would be able to use the gravitational field gradient for propulsion by repetitively creating a field oriented in the desired direction of motion. The process would be somewhat analogous to skiing along a flat surface by temporarily changing the slope immediately ahead of the skis. The UFO pictures often show multiple toroidal optical effects at various distances and orientations relative to the UFO. Therefore, it seems that the localized gravitational field is created anew as needed, and each instantiation can persist for some time after the UFO has moved on. Judging from the picture in Figure 1b, more than one craft may be able to share the same gradient.
The torus in Figure 1b appears to have some discernable fine structure. With a little imagination, it seems to be made up of a chain of smaller tori arranged face-to-face so that they are rings in a larger torus. Perhaps this hierarchical structure with tori of different sizes can be used by a craft to fine-tune its direction of travel.
