Doesn’t the Smaller Body Always Revolve Around the Larger Body?
One of the more common objections to
geocentrism is the claim that Isaac Newton’s laws of
motion prove that the Earth, because it is smaller,
must revolve around the sun, which is larger. In
reality, Newton proved no such thing. A close
examination of his laws reveals that he merely stated,
of two or more bodies in a rotating system, all bodies
will revolve around the center of mass. As Newton
himself put it: "That the center of the system of the
world is immovable. This is acknowledged by all,
although some contend that the Earth, others that the
sun, is fixed in that center.
Granted, in a closed system where the only two
bodies existent are a massive sun and a small Earth,
the center of mass will be much closer to the sun than
the Earth, and thus, in that systemthe Earth would,
indeed, revolve around the sun. But this is precisely
the problem with the appeal to Newtonian mechanics:
the appeal invariably limits the system to two bodies,
the sun and the Earth, while it ignores the rest of the
universe. When the rest of the universe is incorporated
into the system, we now have a center of mass that is
dependent on far more than the local forces we
experience in our tiny solar system. On that basis, as
we shall see, even Newton could not object to the
Earth being the center of mass for the universe. The
grand summation of his three laws of motion (namely,
in a closed system the acceleration of the center of
mass equals zero), will allow an immobile Earth to be
the center, that is, if the universe is included in
Newton’s integral calculus.
…even if there is only one star to take into account, its mass and
gravitational force must be added into the formula for
determining the universe’s center of mass (or
barycenter). In short, our sun, Earth and planets are
not an isolated system. Advocates of heliocentrism
can mount no opposition to this logic since they
believe that our solar system is revolving around the
Milky Way, which, of course, it cannot do unless it is
experiencing a strong gravitational attraction from the
center of the Milky Way. Using that same principle,
when we add to our galaxy the billions of other
galaxies present in the universe, we can certainly
conclude that they will have a substantial effect on
determining the universe’s barycenter. As all modern
physicists agree (even if they don’t prefer the
geocentric model): “Mass there governs inertia
here.”…These distinguished authors are referring to
the total mass of the galaxies and other objects in the
universe that have a direct effect on the inertia we
experience on Earth.
