Is There a Force of Gravity? |
Is There a Force of Gravity?
In undergraduate physics, the Newtonian concept of an attractive force
between masses that is proportional to the product of the masses divided by
the square of their separation is taught. When one advances to the more
advanced concepts of gravitational theory as posed by General Relativity,
the concept seems to change to where what we experience as a force is really
the result of an inertial acceleration in "space-time".
It behooves us then to examine that concept in detail. Consider two
points on the Earth, perhaps London, England and Melbourne, Australia. In
both of these cities, observers experience a downward "pull " towards the
Earth's center. (We can ignore the centrifugal acceleration caused by
Earth's rotation since, at the most, it represents only 0.3% of the Earth's
gravitational acceleration and consider the Earth to be a closed system for
the purposes of the discussion, all velocities and accelerations are
relative to the center of the Earth and, since both London and Melbourne are
nominally at the same elevation which does not change, considerations of
time dilation in the gravitational field are irrelevant. These
clarifications are required because a pair of individuals whose thinking
processes were limited attempted clouds the discussion by introducing them
in response to a previous posting.) Inertial acceleration is defined as the
second derivative of position with respect to time, and since London and
Melbourne are within the closed reference frame represented by the Earth
they do not change their separation with respect to each other but they do
experience the force of gravity as acting in essentially opposite
directions. Since are observed not to undergo spatial acceleration with
respect to each other and the center of the Earth, that observed force of
gravity CANNOT result from an inertial acceleration. It can only result from
an actual force attracting those cities towards the Earth's center in
accordance with the classical Newtonian concept of gravity. It cannot result
from a spatial acceleration in "space-time" as is asserted by specious
interpretations of both Special and General Relativity. The force is REAL.
It is much more than a mathematical abstraction!
In response to a previous posting of this material, the writer received
an E-Mail claiming that the writer was in error. It asserted that Melbourne
and London were really in a "flattened" orbits around the center of the
Earth and experienced the "force" if gravity because they were restrained
from following their null geodesic orbits by the Earth's surface. What
appeared to be the "force" of gravity resulted from that restraint because
it prevented these two cities from following their null geodesic path? This
is a rather frivolous response. If the cities were to fall through the
Earth, the inertial force produced by the resulting second derivative of
position with respect to time and the gravitational force would cancel and
the cities would experience no net force. The attractive force that they
actually experience verifies that gravitational force and inertial
acceleration are different phenomena describing TWO effects, gravitational
attraction and inertial acceleration. There is no way of avoiding the
conclusion that the former applies a force as the result of the proximity of
masses and inertial acceleration applies a force as a result of the second
derivative of position with respect to time. It is only in the never-never
world which mathematics allows one to be foolish enough to consider that
they were different aspects of the same phenomena.
As a digression, the interchange of electric and magnetic energy in a
resonant circuit is conventionally treated as a single phenomena and treated
by a single set of mathematics, as is the interchange of potential energy
and kinetic energy when an object is in orbit. In actuality, in the resonant
circuit, the energy is alternately stored in a capacitor as an electric
stress in its dielectric and is stored in the inductor in its magnetic lines
of force. The actions of both of these devices are independently described
by their own mathematical laws. It is only when they are connected together
do their laws combine to provide an action we experience as resonance in
which energy is cyclicly interchanged between the two devices. I can hold a
charged capacitor in one hand and an inductor in the other hand. It is only
when they are connected together that resonance occurs. The same conculsion
holds true for gravitation. Gravitation forces and acceleration forces are
independent effects which, when coupled, account for orbits as if a single
process were involved. The orbital motion results from the cyclical
interchange of energy between the two independent effects.
Mathematics is a useful tool, but it seems to have been forgotten that
it is only a tool, it should never be used as a substitute for the
intelligence needed to understand of the "mechanism(s)" involved. Physics
seems to be the only science that attempts to abolish "mechanism" and rely
solely on mathematics and experiment. This probably results from the fact
that understanding the "mechanisms" which are involved requires an innate
talent that probably cannot be taught in schools and is as rare as the
musical aptitude which allows an individual to play a violin in Carnegie
Hall. It is no wonder that physicists work so hard to relegate the idea of
"mechanism" to the trash bin of history. It avoids the embarrassment of
admitting that they do not understand their subject.

GravityPhysics
The atom moves in the energy slope because it has more mass on one side
of it's center than the other side.
=A0=A0As the atom is across an energy slope =A0 and up is a gain in mass
then the orbiting parts have less mass when at the bottom of the orbit
than the top.
=A0=A0=A0=A0All of the atoms parts are falling twards the center of the
atom but there is more mass falling in one direction than the other.
=A0=A0This GAIN in energy across evry atom is allways peroprtional to
the weight of the mass.
The gain in mass is F pushing the weight of the atom. The atom is
pushing it's self down the energy slope.

Hey, stooopid spammer Ernest Wittke - Do you want EVIDENCE? Each of
the 24 GPS satellites carries either four cesium atomic clocks or
three rubidum atomic clocks in orbit, with full relativistic
corrections being applied. NAVSTAR Block II GPS satellites (currently
being launched as replacements) have two rubidium and two cesium
atomic clocks.
Internal inconsistencies in SR (meaning inconsistencies of a purely
mathematical logical nature) automatically lead to contradictions in
number theory, itself, and arithmetic, since the mathematics of
Minkowski geometry is equiconsistent with the theory of real numbers
and with arithmetic.

Carroll on what it all means.
Special Relativity is physics on a topologically trivial Lorentzian
manifold with a metric whose curvature tensor is zero. This is a
perfectly diffeomorphism-invariant condition and does not require
any particular coordinate choice. It is invariant under
the full group of diffeomorphisms. The Poincare group is
the group of *isometries* of the metric in special relativity.
The Special Relativity metric is *non-dynamical* (unlike GR). It
defines the coupling *constants* of your theory. If you change the
metric in any nontrivial way you are changing your theory. An
operation can only be called a "symmetry" of a special-relativistic
(non-gravitational) theory if it preserves the metric, and therefore
the symmetry of special-relativistic theories is the Poincare group
only. General Relativity (gravitation) has a dynamic metric.
