About Tom Van Flandern
Lived 1940 – 2009 (aged 68). Tom Van Flandern was an American astronomer.
Thomas Charles Van Flandern (June 26, 1940 – January 9, 2009) was an American astronomer and author who specialized in celestial mechanics. Van Flandern had a career as a professional scientist but was noted as an outspoken proponent of certain fringe views in astronomy, physics, and extraterrestrial life. He also published the non-mainstream Meta Research Bulletin.

Tom Van Flandern was the first child of Robert F. Van Flandern, a police officer, and Anna Mary Haley. His father left the family when Tom was 5. He also helped found a Moonwatchers team while studying at Xavier University; this team broke a tracking record in 1961.
Van Flandern graduated from Xavier University with a B.S. in mathematics (cum laude) in 1962 and was awarded a teaching fellowship at Georgetown University. In 1969, he received a Ph.D. in astronomy from Yale after completing his dissertation on lunar occultations.
Van Flandern worked at the USNO until 1983 , first becoming Chief of the Research Branch and later becoming Chief of the Celestial Mechanics Branch of the Nautical Almanac Office. His espousal of highly non-mainstream beliefs, particularly the exploded planet hypothesis, eventually led to his separation from the USNO. He later said, "This forced me to the 'fringes,' areas of astronomy not accepted as credible by experts of the field".
Following his separation from the USNO, Van Flandern started a business organizing eclipse-viewing expeditions and promoting his non-mainstream views in a newsletter and website. Shortly after he died in 2009, the asteroid 52266 Van Flandern was named in his honor because of his prediction and analysis of lunar occultations at the U.S. Naval Observatory and publications of papers on the dynamics of binary minor planets.
Tom Van Flandern died of colon cancer in Seattle, Washington.
Mainstream scientific work
During the mid-1970s, Van Flandern believed that lunar observations gave evidence of variation in Newton's gravitational constant (G), consistent with a speculative idea that had been put forward by Paul Dirac. In 1974, his essay "A Determination of the Rate of Change of G" was awarded second place by the Gravity Research Foundation. However, in later years, with new data available, Van Flandern himself admitted his findings were flawed and contradicted by more accurate findings based on radio measurements with the Viking landers.
Van Flandern and Henry Fliegel developed a compact algorithm to calculate a Julian date from a Gregorian date that would fit on a single IBM card. They described this in a letter to the editor of a computing magazine in 1968. This was available for use in business applications. The paper set a record for the number of reprints requested from that journal. His non-mainstream 1978 prediction that some asteroids have natural satellites, which was almost universally rejected at the time, was later proven correct when the Galileo spacecraft photographed Dactyl, a satellite of 243 Ida, during its flyby in 1993. how he had become increasingly dissatisfied with the mainstream views of science by the early 1980s. He wrote:
"Events in my life caused me to start questioning my goals and the correctness of everything I had learned. In matters of religion, medicine, biology, physics, and other fields, I came to discover that reality differed seriously from what I had been taught."
In his book, on blogs, lectures, newsletters, and websites, Van Flandern focused on problems in cosmology and physics. He alleged that when experimental evidence is incompatible with mainstream scientific theories, mainstream scientists refuse to acknowledge this to avoid jeopardizing their funding. Van Flandern also speculated that the origin of the human species may well have been on the planet Mars, which he believed was once a moon of a now-exploded "Planet V".
Le Sage's theory of gravitation and the speed of gravity Van Flandern supported Georges-Louis Le Sage's theory of gravitation, according to which gravity is the result of a flux of invisible "ultra-mundane corpuscles" impinging on all objects from all directions at superluminal speeds. He gave public lectures in which he claimed that these particles could be used as a limitless source of free energy and to provide superluminal propulsion for spacecraft.
In 1998 Van Flandern wrote a paper asserting that astronomical observations imply that gravity propagates at least twenty billion times faster than light, or even infinitely fast. Gerald E. Marsh, Charles Nissim-Sabat and Steve Carlip demonstrated that Van Flandern's argument was fallacious.
Face on Mars Van Flandern was a prominent advocate of the belief that certain geological features seen on Mars, especially the "face at Cydonia", are not of natural origin but were produced by intelligent extraterrestrial life, probably the inhabitants of a major planet once located where the asteroid belt presently exists, and which Van Flandern believed had exploded 3.2 million years ago. The claimed artificiality of the "face" was also the topic of a chapter of his 1993 book.
Rejection of Big Bang cosmology Van Flandern was a vocal opponent of the Big Bang model in cosmology and believed in a static universe instead. In 2008, he organized the "Crisis in Cosmology"; a conference of individuals who opposed the Big Bang cosmological models.
