NASA, faced with the
changing trajectories of some of its spacecraft rediscovered the work of Professor
Maurice Allais, which had been, inter alia, published in the USA in 1959, at the request
of Wernher Von Braun, in an article entitled: "Should the Laws of Gravitation Be
Reconsidered ?". This article includes the results of experiments on pendulums,
undertaken by Allais over several years. These experiments had been the subject of several
communications with the French Academy of Sciences, but had failed to interest
NASA used the
eclipse of August 11, 1999 to launch a broad international campaign of tests on
pendulums, mainly of the Foucault type, in order to check the "Allais" effect.
1. LAWS OF
GRAVITATION FROM NEWTON TO EINSTEIN
Most schoolboys have heard all
about Isaac Newton (1644-1727) who, having been hit on the head by a falling apple,
was inspired to find out why, and then came up with the Gravitation Law.
Actually, the truth is that the Law of
Attraction, that attraction varies as the inverse square of the distance, is
the result of an algebraic combination of the laws of Képler (1609).
In 1905, Einstein, by his theory of general
relativity, which rests, in fact, on gravitation, added important considerations. Thus,
one uses these laws to day, to calculate, inter alia, the trajectories of rockets and
