johnreed> In brief: It appears that if we can envisage it as the truth
and the closer we come to believing it is the truth; the greater is
the likelihood that we are wrong. This is not an iron clad rule, but
consider: We think we have proved that a universal force that we call
gravity exists as a property of inanimate matter. We believe it exists
because we feel our weight. We believe it acts on us because we feel
our weight. We define it in units of what we feel, our weight; as the
product of mass and acceleration [mg]. We postulate that inertial
mass [ma] and so called gravitational mass [mg] are equivalent with
respect to the celestial universe because they are equivalent with
respect to what we feel as our weight [mg] and force [ma].
So developing logic through the lens provided by our senses allows us
to define the least action consistent universe after our own least
action consistent image. Our weight as [mg] and a force that we feel
as [ma]. Both [g] and [a] represent acceleration[1]. What does [m]
represent? Mass? What does mass represent? An amount of matter?
Note:
Where we place a balance scale is immaterial to the balance scale.
Wherever we place it the magnitude of [g] will be the same on each pan
regardless of the mass magnitudes placed on the pans (this is true
except in theoretical cases where extreme magnitudes that exist in
mathematical fantasies are projected to vary greatly in very short
distances). So when we define an object in units of [mg] the only
quantity we are comparing on the balance scale is the quantity of mass
[m], since [g] is a consequence of location. That's pretty simple
isn't it? So you might wonder why I bother to point it out.
If [g] was not a consequence of location then mass [m] and [g]
acceleration could not be combined into the product called weight
[mg]. In such a case the balance scale would only give us weight as
[w]. In fact we used the balance scale to give us weight for 6000
years and for 6000 years we believed that heavy objects fall faster
than lighter objects. So when Galileo showed that all objects fall at
the same rate when dropped at the same time from the same height we
were amazed and we have remained amazed for 450 years. So amazed that
we have engaged in extensive research to verify its accuracy.
This is because our normal use for the balance scale was and is to
compare weight [mg]. Weight is specific to location and specific to
what we feel [force] at that location. Weight, [mg], and what we feel
varies according to a location in space. Given any mass [m] all three,
weight, [mg] and what we feel, depend on the magnitude of [g]. We can
change locations and our mass [m] remains unchanged but our weight
[mg] and what we feel varies according to a location in space. Again
its pretty simple stuff. High school physics. So why do I discuss it?
I discuss it because we have defined the universe in terms of a force
that we feel.
We think that the force we feel is proportional everywhere in the
universe (in terms of mass, distance and time), to the magnitudes we
feel and measure on the surface of planets and moons. We calculate a
constant of proportionality [G] that we apply to planets, moons and
stars, by analyzing the behavior of planet surface object mass, where
planet surface object mass is emergent and conserved independent of
the action of planets, moons and stars.
We say that a force we feel as weight [mg] is universally generated by
inanimate and animate matter as an innate property of matter itself.
I say this is false. The force we feel is generated by us (our effort)
and we apply it to inanimate matter and/or feel it through physically
interacting with inanimate and animate matter. The force we feel does
not act at a distance. The force we feel does depend on our location
in space. So "something" acts at a distance.
All atoms fall at the same rate in a vacuum. Therefore I conclude that
the planet attractor acts uniformly on each atom (Einstein proposed a
uniform gravitational field). This is the ‘level’ playing field we are
born in and the field that contains the atoms from which we are built.
Given the level playing field that acts on all atoms 'uniformly'; we
feel the cumulative 'non'-uniform resistance of those atoms when we
'work' against the direction the field of atoms is uniformly pulled.
When we 'travel' in the direction the field uniformly pulls on our
atoms, we experience free fall, or no resistance other than air
resistance.
The 'universal ' attractive action is uniform on the non-uniform atoms
that make up animate and inanimate matter. This is why all atoms fall
at the same rate in a vacuum. The pull on each is uniform. This
uniform pull allows us to feel variance in the resistance of the non-
uniform atoms we work against. An object we lift offers its weight as
resistance to our effort. It offers no resistance to the pull of the
planet. It offers resistance to the force we apply.
Gravitational force is a legacy concept based solely on what we feel;
our weight, and the quantitative least action consistent mathematical
convenience of its definition [mg]. Nothing pulls on us. The pull is
uniform on our atoms which we do not feel during freefall. We feel
our total weight when we are in contact with the planet; or when we
accelerate away from the planet. We feel the resistance of our non-
uniform atoms when we work in opposition to the direction the planet
uniformly pulls on our non-uniform atoms. We feel the resistance of
our non-uniform atoms when we act in opposition to a state of rest or
in opposition to a state of constant motion. In all cases of inertial
mass [ma] and gravitational mass [mg] the force we feel is the
resistance of non-uniform atoms in response to our effort. We act on
this non-uniform resistance and we feel an equal and opposite force
because our effort is equal and opposite to the resistance we act on.
We have defined it that way. [F=mg] and [F=ma].
The force we apply when we lift an object at any location, will
always be equal to the weight of the object's atoms that resist the
force we apply at that location. We generate the force. Matter
provides the resistance we must counter. We feel and generate the
force. It begins and ends in our body and effort. We lift objects.
Objects can strike us. [F=mg] and/or [F=ma]. This does not even imply
that mass generates a universal gravitational force, much less at a
distance.
We have heretofore attributed this phenomenon to Newton's 3rd law. The
"equal and opposite" law because the force we generate is equal and
opposite to the resistance of the non-uniform atoms we work against.
Again we defined the universe through the lens of our own image. Mass
was such a convenient emergent quantity that we required no further
analysis on precisely what mass represents. We could navigate the
planet and the universe in terms of our notion of force.
There is nothing universal about the force we feel [mg] except the
resistance [m] and the location in space [g] that causes it. Our
effort cannot be generalized to the effort of the planet. Inanimate
objects exert no effort. Nonetheless we assign the force we feel to
all inanimate objects based proportionally on the objective resistance
we measure and feel and call mass [m].
The planet attractor acts uniformly on atoms. All atoms fall at the
same rate. We lift or work against the cumulative sum of the non-
uniform resistance of the atoms in an object. The planet attractor
pulls uniformly on the object's non-uniform atoms and on our non-
uniform atoms as we lift the object. To assign the force we feel and
generate, to inanimate object resistance is error.
If you are perplexed and think that this is not what you were taught
in school, you are correct. This is what I have learned and what I am
attempting to explain. I am redefining gravitational force as a force
we feel as living objects in response to resistance. We act on
resistance and we feel the force we generate. The cause of that
resistance is undoubtably universal, it just is not the force we call
gravity. It is the planet attractor's uniform action on non-uniform
atoms. The uniform action on non-uniform atoms by the planet attractor
is why all atoms fall at the same rate. The atoms have no resistance
falling in a vacuum. We feel the resistance we call force and weight
when we interact with matter on the playing field equalized by the
uniform attractive action on all atoms. We can quantify this
resistance in units as a product of mass and acceleration [ma] and/or
[mg]. I will further explain why this works when I continue.

Related notes:
[1] The simplest case of acceleration can be expressed as a change of
speed over time. Take the most familiar US definition for speed as
miles per hour or [m/h]. This is [distance/time] or [d/t]. [Speed]
over [time] then becomes [d/t]/[t] which is [d/t^2].
[1] Where mass is the conserved cumulative resistance of non-uniform
planet and moon surface atoms and is conserved independent of the
celestial least action motion: Recall that we have spin angular
momentum and linear momentum from Newton’s first law. We don’t have
orbital angular momentum from that law. We acquire orbital angular
momentum from Newton’s mathematical derivation for centripetal force
where he used a perfect circle and perfect motion to argue for
centripetal acceleration.
The spinning perfect circle angular velocity is an artifact of the
uniformly spinning circle itself. The angular velocity of a spinning
disk, sphere, or solid object, is an artifact of the uniformly
spinning disk, sphere, or solid. So we have least action consistent
single object spin angular momentum as an artifact of the spinning
perfect circle angular velocity.
Newton then used the least action consistent angular velocity of
Kepler’s empirical time controlled law of areas for 2 body planet
orbital motion, to mathematically carry his perfectly circular 2 body
uniform motion, spin angular momentum analog, to the planet’s non-
uniform 2 body orbital motion.
It’s based solely on time-space parameters where the emergent
conserved cumulative resistance of non-uniform planet and moon surface
atoms is either designated as the cause of the least action consistent
celestial motion (Newton’s gravity), or as the consequence of the
least action consistent motion, as space-time curvature (Albert
Einstein and peers).

I have made it easier to reference my supporting work by creating a
Google Science and Technology Group titled: "The Least Action
Consistent Universe and the Mathematics". Currently it contains
Sections 1 through 9 for reference. The many sub-sections and work
prior to 2007 has not been included. I will develop it further as I
have the time and gain familiarity with the venue. Meanwhile my more
recent work is available for public review to all, and open to
criticism and discussion by any person who joins the group. The
latter is a condition established by Google and newsgroups in general.
I provide information. I seek no recruits. However, there are no
