In 1687 Newton published the "Principia", in which he described his theory of gravity and the cosmos. His theory of gravity, as he saw it, provided a fundamental basis to explain "the System of the World". The hypothesis was that gravitation
was universal and mutual by degrees of the inverse squared, but throughout the "Prinicipia" and even today the
cause of "gravity" remains unassigned, and in his lifetime he never measured it.
In fact, gravity, so-called,
as a real and active force in Newtonian physics, was not measured until 111 years after the "Principia", by Cavendish, with a torsion balance in 1798. From an experiment with a torsion balance, the empirical measurement of the supposed universal gravitational constant, there obtained, and that is written
as "G", added to Newton's theory and would also form part of the basis for the equation of the force of gravity
that is accepted today, to wit:
F1 = F2 = G(m1m2)/r^2
where F1 and F2 is the force of gravitational attraction between two particles, masses, or objects, of whatever in whatever kind,
however it may be, and "G" is the universal gravitational constant, and m1 and m2 are the two different masses, indeed
the first and second mass, and r is the radius distance between them, as such and so forth, also and/or of the two centers of the masses.
The formula for the expression of
the force of gravity involved in gravitation that is taken from Newton's "Principia" can be obtained from Propositions
74 and 75, and Theorems 34 and 35. In these passages the idea is that, "Every point mass attracts every single
other point mass by a force pointing along the line intersecting both points. The force is proportional to the product of the two masses and inversely proportional to the square of the distance between them."-1
is taught that according to the law of universal gravitation, the attractive force (F) between two bodies is proportional to the product of their masses (m1 and m2), and inversely proportional to the square of the distance, r, (inverse-square law) between them:
F1 = F2 = G(m1m2/r^2)
may seem okay to some people, but what is "G" really,
if it was further obtained with a measurement taken from a torsion balance?
It must not be first or an independent value as much as the number one of it, for itself, that would divide everything, also the torsion balance, of course, since a torsion balance cannot measure "gravity" beyond its own tension, mass, pressure, balance, weight, density, structure
and design. And whatever the torsion balance was supposedly measuring in terms of "G" could have been measured with anything else, since all other things that could be used to measure
gravity have weight, mass, density, tension, pressure, balance, structure and design too, as much as the number one of them or it, for any other situation, and "G", according
to Newton and heliocentrism, is universal and ever present
If "G" really is the universal gravitational constant of proportionality, for gravity, why measure it with a torsion balance, when one can measure it with a pack of cigarettes or a little box of matches at the corner
store? Because Cavendish and his torsion balance in the laboratory give better scientific cover, white
coat bona fides, of course, than a pack of cigarettes at the corner or the liquor store.
"Yippy skippy", smart alecks may say, yet "it is a great mistake to suppose that scientific truths differ essentially from those of every day. An eye armed with a microscope is only a human eye after all. It sees
more than the naked eye does, but not in any different way."-2
However, as significant as it has become,
and as common as it is, it remains very difficult to measure "G" with any high degree of accuracy. A certain amount of density first is always needed in the test to measure gravity. If things are too rarefied, one will not be able to get a good measurement.
To get Newton's gravity, there is indeed some density required, yet not much more than the things themselves. For example, if one did want to measure gravity with a pack of cigarettes, rather than a torsion balance, at the liquor store, it will be better to examine "G"
with the solid pack first, as something with required density, rather than with the smoke. If one tries to measure gravity with the smoke, one will get more smoke ... obviously .. and mirrors perhaps in a back room ... than "gravity", because smoke does not fall down to the Earth with much tension of force.
Also, do not test the force of gravity too much with the light that comes from a short match by pointing the
match down. Such a light is not moved by gravity, and the flame is an anti-gravity device that will go up the little stick and burn the fingers. The same thing occurs with a fireplace: the wood stays down while the fire goes up. Therefore, wait and blow the
flame of a lit match out first and test gravity with the burnt stick. The wood is denser than air and will yield a fair enough test of the forces of tension, accomodation, and gravity in that case, as well as any torsion balance.
Ignis ardens, per proprietatem ascensionis suamet, deforis
esse tractuum gravitatis: burning fire, by its own property of ascension, is outside the pull of gravity. A foot long match may be useful for testing the proof further, since the flame will tend to go out early, before the end of the stick, unless one points
it down. Once pointed down, however, a flame that was about to go out will increase and climb up, getting more oxygen to climb up against gravity, for new life, until it consumes the other end of the stick. A scientist can switch hands and hold the burnt end of a long match, and let the little fireball climb all the way up the height at the other end. The fire naturally looks for wood and air that it can find, as high as it may go to
the treetops, et cetera.
Whether testing the force of gravity with a torsion balance or cigarettes, the discovery will be that gravity is weaker than even the tiniest
refrigerator magnet in the whole wide world ... or the littlest lovebugs, Bibionidae or Plecia neartica. Even the chorus box of scientists admit that it is by far the weakest of forces, and the weakest of the four fundamental interactions, described in modernist
physics; yet according to Newton and heliocentrism it is everywhere, high and low, and is what is keeping the grand symphony of cosmic things together and in motion.
After testing these things scientifically, however, some investigators perhaps would disagree, and reasonably conclude that Newton's "gravitation" is the vaguest thing possible that is
not an act of complete disutility.
For instance, it could go without saying that gravity itself
does not itself move alone -- "suamet ipse" -- as it is or would be strictly imposed most simplewise by itself. Not moving itself alone, and not set in sequence by itself alone yet among things, its own supposed principle of operation does not move,
except where there are first objects in the course. Surely there must be objects for gravity to move, to set any force in motion, and since there must always be objects -- otherwise there would not be gravity -- there must be objects first.
Yet mere objects themselves are not in the category of first mover. They only go so far but they always come before
gravity, since gravity is after all objects that it would move, for where there is no principle object there is no gravity. As much as an all-involved point, even though hypothetical forms of Newtonian gravitation supposedly would set things in motion, gravity does not move anything laterally anyway. And it cannot move things only vertically, since the Earth and the cosmos
are spherical. Since it is known that objects do not move themselves but are moved, whatever way they go, it is fair to say that gravity, or what is called Newtonian gravitation, does not move objects, since what moves objects must come first.
And there once was a Hollywood actress, a beauty queen who became famous for running up and down the beach almost
naked, and flirting with short men. She was a sometime guest on talk shows, and during one it was discovered that she could not remember where she had gone to High School. For all the talent and experience, she had forgotten about it almost totally, and it
was obvious that school had not been a top priority. In fact, it was discovered that she had been a regular truant, and had been skipping school and going to the beach for many days and days before she got lucky and became an actress.
"I was learning things", she said, "you know, not first things other things."
