We report misleading effects of human-origin signals on very distant gravity
experiments in solar eclipse days. Despite Newton's well-established gravity,
some research has been underway for some years on alleged gravitational
anomalies in the days of solar eclipses, as per still considered reports in
mainstream peer-reviewed journals. In solar eclipse days some instruments,
notably pendulums and gravimeters, had provided anomalies that were
interpreted as unknown features of gravity. French physicist Maurice Allais is
credited with first reporting pendulum anomalies during a solar eclipse in 1954.
NASA researchers also wanted to investigate the matter, also because they were
looking for an explanation for the so-called Pioneer anomaly (explained later),
and promoted a worldwide test for the solar eclipse of August 11, 1999. We were
recruited for that experiment in July 1999 following our proposal for an innovative
experiment. We have since conducted two experiments with stationary
pendulums and recorded surprisingly structured anomalies which after years of
study proved unnatural. We report these tests with extensive control data, and a
limited number of similar anomalies observed by others, some already published
but still not as unnatural. In summary we analyze: our stationary pendulum test
on Aug 11 1999 in South Italy (unpublished); our stationary pendulum test on
May 31 2003 in South Italy (unpublished); a gravimeter test by University of
Trieste (Italy) on Aug 11 1999 (unpublished); a report from Reading (UK) for the
Aug 11 1999 eclipse (published); a report from Manavgat (Turkey) for the March
29 2006 eclipse (published); a report from Kiev (Ukraine) for the Sept 11 2007
eclipse (published). In the above experiments we found abnormal instrumental
behaviors (sudden sharp micro-deviations) that obey a precise structure of
equally spaced time markers. The timing scheme was always the same in all of
the above experiments. Subsequent research revealed that the scheme matched
the one used by a very distant source of high-power, man-made, controlled radio
signals. We conclude that the measuring instruments tracked by chance a
campaign of RF-based eclipse experiments over the years, not gravitational
phenomena. We report in more detail our two pendulum experiments and the
gravimetric test of University of Trieste, spending fewer words on the other tests
already described in their respective articles.
