Do you believe that there physically exists objects located in space that
have characteristics (e.g., mass and/or charge) that simply are what they
are, and these "intrinsic values" do not at all change regardless of
whether
or not these values are being, or attempted to being, observed? For
matter,
we know the basic structure presented by nature to the macroscopic world
is
atoms bonded to other atoms, for example, a large crystal of iron we can
pick up and hold in our hands. After centuries of theoretical and applied
science, we now know a chunk of pure iron is made up of atoms and the iron
atoms are made up of electrons, protons and neutrons. Consider an
electron.
It has mass. Do you believe this mass is somehow fundamentally intrinsic
to
the electron? Please try to put aside any "observatory-centric" bias. This
question has nothing to do with measuring this mass, it is a question
about
how you think the real world is made up. Your "physic." Is the matter
outside of you mind actually matter "out there," e.g., do you think the
electron that exists in the water in your toilet, right now, is a bit of
matter that has nothing to do with you in terms of what its fundamental
characteristics are? Do you believe in an "external world, independent of
the perceiving subject" (which is how Einstein put it)? Strange, isn't it,
someone who is accorded with the birthing of the idea that "everything is
relative" did in fact believe in a completely independent external world.
He
called this belief the "basis of all natural science." If there is an
external world, it's characteristics *must* be independent of observation,
for how else can it be "external"? Certainly we need to shine EM radiation
to observe, and that perturbs atomic systems compared to us not shining,
but
when the atom gets perturbed, it is still a completely independent of
*you*
event. You set the characteristics of the EM radiation, but exactly what
are
the "independent natural laws" that govern the matter/radiation
interaction
have nothing to do with what you, me or anyone *thinks* they are. We do
not
have the power to change what nature *is*, we only have the power to
figure
out how nature *works.* Even if we could completely figure out how nature
works, we couldn't change it. That is, if you believe in an independent
external world, which "works" in whatever way it "works" which we in no
way
whatsoever can change.
If there is an absolute "rest mass" some particle has, such as an
electron's
"rest mass" this in a certain sense demands an absolute coordinate system
for the universe. There also needs to be some physical mechanism by which
an
electron can physically change its mass when it has motion in this
absolute
universal coordinate system. I have ideas about how this might happen. On
a
level higher, the atoms of a ruler must somehow be physically affected
into
a closer-together bonding structure if indeed length contraction is
physically real in an independent external world. The atoms literally get
closer together if the ruler is moving in this absolute universal
coordinate
system/frame. If this is indeed what physically happens, this happens
whether or not there are any conscient beings anywhere in the universe,
and
the "ruler" were simply a chunk of iron coasting in this big gigantic
universal space completely devoid of any intelligence anywhere.
Steve Bell
xxein: You express your thoughts well. I share them. Now what do we
do about it?
Thanks. I thought you would from reading other of your comments. If you take
all this literally, i.e. that there physically exists matter distributed in
some absolute universal space, it seems to me natural to think that matter
is fundamentally particulate at a point in time and is in no way a wave.
This belief is either right or wrong, but I think that at every point in
time we call "the present" every single electron in the entire universe is
an actual uniquely-existing particle. That is, all (and I mean *all*) of an
electron's matter is confined to some small volume of space. It is "here"
and absolutely none of it is "there." This means regarding an electron, in
no way can it physically be any type of standing wave, which is everywhere
at once. There is no "probability of the electron being anywhere" except
inside the volume of space from its surface on downwards to its center. Each
and every electron at an instant in time is not spread out in space, or I
should say its center of mass is at some exact (x,y,z) location in the
universal coordinate system. In this paradigm, this is the physical truth of
how an electron exists, and has nothing to do with whether or not we are or
are not trying to measure the electron's position. Our measurements will
affect where the electron goes after an interaction with our machine's EM
radiation, but that does not at all change the electron's fundamentally
particulate, non-wave way "it exists" in the universe. After accepting a
completely-particulate, none-wave paradigm, there can be formulated a
completely particulate unified field theory, and that is where I have
attempted to contribute. But it will be rejected because it postulates
particles are actually true particles at points in time with definite,
exactly located centers of masses with exact and definite velocity vectors
attached. This particulate-based unified field theory is a theory of
geodesic motion in a unified gravitoelectromagnetic field, and it would be
rejected by QM if I presented it.

xxein: Don't get too excited with that. There may be other factors
missing or come to play in a different manner. Let it be known that I
do not see a TOE coming anytime soon. But I do see wrong approaches
to it. Most believe that past ideas and theories are somehow proven
or sacrosanct or just believable. When I have to use pure logic,
nothing coincides well.
I was blessed with an ignorance when I first started to study
Relativity at age 40 ('85). I had heard and accepted it all up to
then through only sketchy descriptions. I was somehow mature enough
in thinking these things out to logical conclusions. I really don't
know how, but I did. Nothing was logical.
I was never that great at math and/but soon realized that it was a
math that was holding theories together. There was no logical
physic. It was all a description held together with a math. -
Relative observations tied together through enough consistency of
observation, but without a physical logic as any type of objective
structure. It couldn't survive logical scrutiny.
Without having heard of Lorentz, I came to his conclusion. When I
finally did read Lorentz and found him out, I felt pretty good ('8 .
I was doing something right. But there was no gravity there. This is
where I had to shift into a lower gear, like quantum considerations,
to try and find out the cause of gravity from the objective and
mechanistic view or logic.
Logic showed me that it is an energy movement. This meant an energy
field. Not that it couldn't be sort of static on a local level, but
on the global level, it had to be non-homogeneous. It had to jive
with both universal expansion AND local gravity situations. Through
the dreaded subjective observational technique, we can peer into
something that is more objective --- but only at large scale.
In the smaller scale, where expansion succumbs to gravity (~~=/
Quote: galactic), we lose any objective observation. And because we live in
a galaxy, our view is still somewhat distorted but we think we have
figured that part out. Well not quite. We still cling to old
theories and beliefs and that is how we tend to figure things out.
All we have managed to do is propose a quandary with the supposed
solution of a cosmological constant. Einstein didn't even like it,
for Pete's sake. It is only a math to MAKE things work as we might
envision them.
So finally getting to your electron particle vs. wave, I share your
thoughts, but there is something else that must happen. It must be
able to share and transfer energy. Not only that, it must require
energy to do it. The energy must come from somewhere to keep this non-
inertial state of existence. If it didn't have an external source, it
would wither away into a vacuum as energy used like a dead battery.
OK. We don't have a physical clue as to why our universe exists. Nor
do we have a clue as to whether other universes exist. We sort of
throw up our hands an invent gods. Where did they come from? Worth
mentioning but way above the immediate issue of what kind of stable
physic is there. It, by all accounts, is predictable on many, if not
all, scales of measurement. It is our universe to behold. It is set
into its own physic and we try to figure it out. There's nothing that
appears to affect it in a willy-nilly fashion.
Then you might wonder how photons can exist or travel at their speed
for billions of years. This is a two-parter you can ask me about
later. It gets into what "particles" are made of. The false sense of
the photo-electric effect and other issues.
But mostly with the particle consideration of an electron and its
energy as a non-inertial entity, it has to go all the way up the
physical ladder into what the physic actually is.
All this leaves only one solution/description for gravity.
But when it comes down to it all, an electron is not a photon. And I
still don't trust the establishment position to be able to give a
logical physical explanation. In a way they do with quantum theories,
but qt's have not been able to fathom gravity.
What would you like to discuss next? |

"Let us discuss the difference between Einstein’s and Lorentz’spoints

the theory independent of any assumptions about the constitution of
matter. Should one, then,...completely abandon any attempt to explain
the Lorentz contraction atomistically? We think the answer to this
question should be No. The contraction of a measuring rod is not an
elementary but a very complicated process. It would not take place
except for the covariance with respect to the Lorentz group of the
basic equations of the electron theory, as well as of those laws, as
yet unknown to us, which determine the cohesion of the electron
itself. We can only postulate that this is so, knowing that then the
theory will be capable of explaining atomistically the behaviour of
moving rods and clocks." (Pauli, Theory of Relativity, 1921)
Einsteinians love Pauli but are reluctant to explain length
contraction "atomistically". They used to teach Einstein zombie world
that the effect is "one of perspective" but now neither teachers nor
students think the effect is "one of perspective". They don't even
think the effect is "not one of perspective". They just don't give a
shit about length contraction or any other idiotic corollary of
Einstein's 1905 false light postulate. Divine Albert's Divine Theory

xxein: I mostly agree, but what is the true physic?
There is a physical explanation here of how motion would slow the
ticking of light clocks.

GPS Clocks Using the Physical Behaviour of Moving Clockshttp://www.scieng.flinders.edu.au/cpes/people/cahill_r/V14N4MCA.pdf
Finding a physical explantion of length contraction is more tricky.
But suppose the average distance of an electron from the nucleus of an
atom (lets assume spherical symmetry for simplicity) is related to the
two way travel time for virtual photons traveling between the nucleus
and the electron.
Then if the atom was moving relative to 3-space and the electron
orbital remained spherically symmetrical in the 3-space frame, the
average two way travel time for virtual photons in the direction
parallel to the motion would become longer than the average two way
travel time perpendicular to the motion.
However, if we assume that the electron tends to adjust its motion to
maintain two way travel times that are the same in all directions[#],
then the orbital of the electron would contract in the direction of
motion, so as to maintain such equal travel times.
# Eg. The two way travel time of virtual photons travelling
between an electron and the nucleus might provide
the only indication of distance between the two.
If so, an atom would "believe" it has a spherical
orbital when the two way travel time for virtual
photons between the nucleus and the electron in
the orbital, is the same in all directions.
The relative degree of contraction would be the same as that required
to maintain equal two way travel times for light in vacuum in the two
arms of an MM interferomenter, if one arm was pointing in the
direction of motion and the other was perpendicular to the motion.

xxein: It is more tricky to be sure. Our science isn't up to it yet.
The key is to ID the difference between how light can move vs. how
matter can move.
Matter depends upon how light can move. Given even a static sea, if
matter moves through it, the energy exchange will have to follow suit
(Lorentz). But the energy exchange has to follow with the sea also.
It becomes biased to a direction.
Don't read Bohr or orbiting electrons or clouds here. Just understand
that we see these seemingly biases all the time. They are not
peculiar. They are the physic we seek. But to which context do we
place it?

Quote: I just thought of something. A 3-d gyroscope. Does that give rise to

Holy crap! Inertia.
I knew it was there. I just didn't know how or why. Just remember I
said "change of energy flow" and resistance to it. Gyroscopic.

Induced dipoles have this "3D" property.
<<The Machian inertia appears on cosmic scales from
bound coherent states through this tunneling electromagnetic
radiation. In an elliptic Universe, the very low frequency
modes of the coupled oscillators can be identified with
those of their radiative antipodal image. As a result,
far infrared coherent modes are expected to arise in the
Universe that lies within their realm, in which the local
oscillators intrinsically partake, inducing gravity. >>

We could go from bottom up, but I like to go from top down. To me, it is of
fundamental importance to describe the space of the universe. The best
mental picture I can think of that I believe reflects reality is a gigantic
"laboratory coordinate frame" within which resides all of the cosmic web.
And I mean all of it, not just the stuff we've mapped out yet. The statement
I just made has nothing to do with us observing anything. It is an absolute
statement about the true characteristic of the external world that is either
true or not true. To make it clear, I am referring to a big gigantic space
which physically exists at an instant in time we call "the present" and
contains, in that instant, all of the matter of the universe. I believe
modern cosmology has made the statement that space on this scale is flat.
But that's taking the standard paradigm that spacetime is GR, and physically
curved or not curved, etc. This paradigm says there is no such a thing as a
true physical force nor acceleration. Everything is from the "perspective of
the observer." I believe though, one can interpret the reason why we use
differential geometry, separately from the idea that geometry itself as
having some kind of physical existence. To me, space is physical, but
geometry is just our mathematical modeling of this space. The reason why we
should (and really, must) use coordinate invariant mathematical development
is for consistency of communication. I can develop a final set of equations
of motion for a rotating laboratory frame, that if I gave to you and did not
tell you what frame I used, you would say they are different equations of
motion compared to what you think are the correct ones. When we all agree on
coordinate invariant mathematics, we all come up with the same equations of
motion, the same form for these equations. This and only this, can be the
sole basis of why we use curved geometry to model gravity. In a certain way,
what I have just described is the principle of equivalence.
Against all (probably) who read this, I really don't think physical space is
curved. I think the gigantic space of the universe is essentially absolute
Newtonian, that is, flat Euclidean-Cartesian if you need to put a math tag
to it. This resolves all kinds of things, basically almost all of the SR
arguments on this list, which are fundamentally all about the symmetry
that's needed for coordinate invariant mathematics. People seem to me to
have taken too far the meaning of this symmetry, interpreting each
"perspective" as being equally physically real. If indeed there is an
absolute frame, then the true physical states of bits of matter like
electrons are absolutely relative to this universal truly physically flat
space. In this universal frame, indeed there are true physical forces and
true physical accelerations, and the equations of differential geometry give
us equations of motion that map out non-Newtonian motion in the flat space
of the universe. This is true on all scales, from the orbiting of bits of
matter we know as planets around nuclei we know as stars, or other bits of
matter we know as electrons orbiting around atomic nuclei.

"laboratory coordinate frame" within which resides all of the cosmic web.
And I mean all of it, not just the stuff we've mapped out yet. The statement
I just made has nothing to do with us observing anything. It is an absolute
statement about the true characteristic of the external world that is either
true or not true. To make it clear, I am referring to a big gigantic space
which physically exists at an instant in time we call "the present" and
contains, in that instant, all of the matter of the universe. I believe
modern cosmology has made the statement that space on this scale is flat.
But that's taking the standard paradigm that spacetime is GR, and physically
curved or not curved, etc. This paradigm says there is no such a thing as a
true physical force nor acceleration. Everything is from the "perspective of
the observer." I believe though, one can interpret the reason why we use
differential geometry, separately from the idea that geometry itself as
having some kind of physical existence. To me, space is physical, but
geometry is just our mathematical modeling of this space. The reason why we
should (and really, must) use coordinate invariant mathematical development
is for consistency of communication. I can develop a final set of equations
of motion for a rotating laboratory frame, that if I gave to you and did not
tell you what frame I used, you would say they are different equations of
motion compared to what you think are the correct ones. When we all agree on
coordinate invariant mathematics, we all come up with the same equations of
motion, the same form for these equations. This and only this, can be the
sole basis of why we use curved geometry to model gravity. In a certain way,
what I have just described is the principle of equivalence.
Against all (probably) who read this, I really don't think physical space is
curved. I think the gigantic space of the universe is essentially absolute
Newtonian, that is, flat Euclidean-Cartesian if you need to put a math tag
to it. This resolves all kinds of things, basically almost all of the SR
arguments on this list, which are fundamentally all about the symmetry
that's needed for coordinate invariant mathematics. People seem to me to
have taken too far the meaning of this symmetry, interpreting each
"perspective" as being equally physically real. If indeed there is an
absolute frame, then the true physical states of bits of matter like
electrons are absolutely relative to this universal truly physically flat
space. In this universal frame, indeed there are true physical forces and
true physical accelerations, and the equations of differential geometry give
us equations of motion that map out non-Newtonian motion in the flat space
of the universe. This is true on all scales, from the orbiting of bits of
matter we know as planets around nuclei we know as stars, or other bits of
matter we know as electrons orbiting around atomic nuclei.

xxein: Here we depart. An empty space which contains multi-universes
"was" flat as you say, it was for all purposes void. But it had to
contain something like a grain of sand per volume of an ocean. Many
grains per many such contiguous oceans. But let's limit it to our
territory. Our universe.
This grain. We don't know its history. We don't know the history of
the universe, either, except in its present epoch. We can see it
expanding and and yet see a gravity at work that can cause another
grain of sand in a lesser ocean (BH's). We don't know the extent of
this behavior. We don't know if this is iterative or reiterative in
physical function. But we do know there is a non-homogeneity.
We don't know what grandfathered all this and it is possible that a
magnasuprema BH started it all. Otoh, we don't know if mini BH's
eventually came together through a gravity to produce the
magnasuprema.
What we do know is non-homogeneity. Active non-homogeneity. Movement
and energy transfers. In this way, our near space appears curved. It
may be primarily do to how we can "see it". We rely on light.
If you think about it, we don't consider what escapes from a
universe. We have a limit of observation that constrains us to only
consider what we "see". And possibly in this fact, an artificial
cosmological constant may be derived to balance expansion and
gravity. (Just a guess).
Viewing a universe objectively, godlike, it appears there are
gravitational concentrics. Super-galaxies seem to be a semi-
definitive crossing point for this behavior.
And now I ask you if there is a curvature to behold. By what method
do we behold? Should it be by belief, math or logic?
I am well aware of what we call invariant math. It had a good start
from Lorentz and was continued with Einstein's theories. Did you ever
think of how a continuity might exist and how you would measure and
make a math within it? It's a fascinating study.
Now precisely because there is continual change, there have to be
either forces or curvature experienced by inertial objects. I tend to
seek a force that provides for a field that looks like a curvature.
So just a different name for the same thing. Different math
descriptions, of course. That why math is not the physic. But there
is plenty of false physical logic to accompany it (of course).
I have found out through study and logic that there are many common
things we accept as solid science that are untrue. It is through the
use of this math invariancy that we can become confused and
disorientated. It is in both local and global views that this is
effective/affected. It goes back to your wish you could see the
universe from he outside perspective.
I was just watching Carl Sagan's cosmology series. He was a brilliant
spokesman. I am not. Yet I may know more pertinant stuff and be able
to put it together in a more logical way. When I was hunting rabbits,
I couldn't see snakes. When I was hunting snakes, I couldn't see
rabbits. When I am hunting a physic or a cosmology, I do not see
anything that does not follow a logic. An invasive math is just
that. Almost like a virus to our thinking.
So what is gravity? Is it a force or a curvature? I already gave you
a try at what I thought. There has to be a reason that gravity
exists. I don't know QM and how all the charges and 'colors' exist as
being able to define separate entity particles, but I know it can't
climb upward to describe gravity in that way.
I can believe, however, that any energy trapped into such a QM system
is not inertial. It would require outside energy to maintain its
form. I think this is the reason that any structured form or field is
gravimetric.
To go further, into energy, itself, you can't deny a continuity. This
means there is a continuity between energy and mass. One of the
requisite functions of staying in mass form is the input of energy.
Nothing is inertial. It only appears that way and can be described in
that way if you neglect the flow of energy or mass required to exist.
So, it is easy to discern where a mass is in a diffuse field of
energy. But it is only 10^-34 in QM. Fortunately, we can view the
cosmos. We get another perspective. Into what singular physic do we
insert these things?
A universe must have laws by which it operates. If there are other
generated universes, I might not expect that they abide by the same
laws. But perhaps only the notion of a cosmological constant to
provide for a proportianality, but any one region of space does not
necessarily share the the same conditions.
I can easily believe that a physic can be distorted even between
universes. Btim that the internal measurement might prove to the
internal observer that there is a different cosmological constant.
So? Is a cosmological constant only locally made and verified? Are
there super-universal laws provided by an existing (pre-) occupied
space or is space empty? I can comprehend both.
Let's short circuit a little here. To have activity, there must be a
presence. Something exists. Would another possible universe
necessarily create its laws the same as ours? That might depend on
the pre-existing conditions in which it found itself. Does this mean
that there were actually pre-existing conditions? Chicken and egg?
What should we think?
I don't want to bring up the subject of evolution here, but rather
steer it toward the notion of a physical iterative process. Yeah, we
exist and can measure some things. But we cannot measure that which
we do not suspect.
Yup, there are crackpot theories out there. There is also the horn.
Let's clear the guano out of it.
What! It reads the same? let's rise above the guano. |
