A
careful study of the PRINCIPIA [1][2][3][4][5] brings us to an
extraordinary conclusion: Newton, without realizing the fact (and all
of us with him), makes a correction to the law of falling bodies by
Galilei! By means of his formulas we find immediately that, near the
surface of the Earth, a heavy body would fall quickly than a light
body, but the difference in time, easy to find theoretically, is so
small that, even today, it cannot be detected experimentally.
On the other hand, even if Newton's forecast on the fall of bodies
(and, thus, in the restricted terrestrial environment) are still
unreachable, their implications in the solar system scale are really
exceptional and extraordinary.
We will show that Le Verrier and Newcomb made an error, both in concept
and in calculations, concerning the motion of Mercury's perihelion.
This enables us to highlight (using only the power of Newton's
equations) the fundamental and always neglected role of the action of
the gravitational mass of a generic planet onto the Sun. This action
actually is an induced movement of the Sun, always considered
absolutely fixed, that causes a slippage, towards the gamma point, that
is directly proportional to the gravitational mass of the orbiting body.
Making use of incontrovertible and elementary physical considerations,
we will discover that, while Mercury moves the Sun towards the gamma
point by 44'' per century, Jupiter - the giant of the solar system -
moves the Sun by 52'' per year, and the Earth by only 2'' per year. We
immediately deduce a fact of exceptional importance: the grand,
concrete and undeniable astronomical phenomenon known today as
lunisolar precession, never clearly interpreted, is not due to the own
movement of the gamma point towards the Sun - considered absolutely
fixed according to the qualified and debatable ad hoc version of Newton
- but instead should be ascribed for a non negligible portion, to the
real motion of the Sun towards the gamma point. This motion is due, as
already stated, to the gravitational movement that all planets induce,
in various magnitudes, onto the Sun. Thus the difference between the
52'' caused by Jupiter and the 2'' caused by the Earth, that is exactly
equal to the 50'' of the actual lunisolar precession, no more appears
to be a coincidence. In other terms, as we will specifically establish
with exact calculations, the terrestrial or local effect of the
inaccuracy of Galilei's law becomes, in the astronomical domain, both
an interpretation of the unexplainable and slight movement (precession)
of Mercury's perihelion and a new and clear reformulation of the
undeniable and concrete precession, that today is named lunisolar
precession. Therefore the criticism of Bernoulli, Euler and d'Alembert
is true… |
