Object: Anti-Relativistists Main Points (Einstein Abstraction or Reality)
Anti-Relativitists main points are, how can
something physicists model as geometry for the
sake of mathematics become equated to
reality where time can literally slow at
relativistic speed or near strong gravity.
Your comments would likely be for them
to study metric tensors, advanced vector
and differential calculus, etc. But isn't there
an intuitive way to explain SR,GR. I mean,
which part of it is physical and which part
is mathematical. You can say they are just
stupid not understanding it. Well. We need
to have layman friendly version of it too,
it's not just for anti-relativistists but for
ordinary folks who just want to have an
intuitive feel for Relativity who don't have
a decade of free time to study it because they
are tied up to business and home duties for
example. Of course math is important and
essential but there should be a physical part of
it as time indeed can slow down, etc.. For those
who studied relativity for a decade or more.
Pls. share which part of the geometry or math
model actually pertain to reality where time can
slow time literally or the physical basis of relativity.
We can use mathematical model to explain
sex like how momentum and tensors can
model the movements of the body, but you
can explain it too like how muscles move the
body and how that thing is inserted without
using the concept of ballistics or kinetic and
potential energy, etc. So with relativity likewise.
Which part of the geometry or math model is physical
and which of it is modelled as geometry for sake of
illustration or calculations. In other words, what's
the physical basis or correlates or causal mechanism
of Relativity.

Yes that is true. But why that is can only be discussed once you have a
certain mathematical background. Penrose does a good job of providing that.

I
read how Einstein at first is not interested in Minkowski
concept. Einstein said, "The main thing is the content,
not the mathematics. With mathematics, you can prove
anything." Later Einstein encompassed Minkowski view
and GR was born. I guess the key is to think the Minkowski
way.


There are many routes to GR. The modern one is to ask the question why did
nature single out Minkowski geometry as special. GR says no geometry is
special - it is dynamical.

Maybe Minkowski geometry is lower harmonic mode of a higher
dimensional space (see stuff about Kaluza Klein below)?


The idea of the unification through symmetry hit
me because I know particle physics is based on
Gauge Symmetries like Su(2), Su(3), etc. My background
before is only non-relativistic quantum mechanics and
semi-relativistic quantum field theory (which of course includes
SR but not Minkowski concept).


If it has SR then it includes Minkowski space.

When Einstein produced Special Relativity in 1905. There is
no Minkowski space in his papers. It is only after Minkowski
read about it that he developed the SR concept into space and
time as one in the form of Minkowski space. Later after Einstein
thought about equivalence principle and gravity and all those.
He searched for a geometry that can encompass those. Then
isn't it Grossman pointed him to Minkowski teaching about
Riemann geometry powerful enough (at that time) to explain the
bending of space and time...
Anyway I have a question for you. I'm contemplating about Kaluza
Klein theory. Nearly a century ago. Kaluza had wondered,
as mathematicians do, how relativity equations would look if written
down to represent five dimensions. He found that this five-dimensional
version of General Relativity included gravity, as before, but also
another set of field equations, describing another force. The
force is Maxwell's equations of electromagnetism. Kaluza
had unified gravity and electromagnetism in one package.
Electromagnetism seemed to be simply gravity operating in
the fifth dimension.
Bill. Based on your mathematical knowledge and analysis of it.
Do you think its just a mathematical trick? Because if its not,
then it should be made a basic fundamental concept due to its
sheer elegance. And in addition to SR, GR as the definite concept..
I have to accomodate Kaluza Klein as a fundamental to
accomodate my world.
I'm looking for this model wherein Randall infinite dimensions
is combined with non-locality where spaces far apart is only
throw a planck stone away. I can't visualize 5D or 6D space
but in such space, is it possible that distance far apart is
only near?. For examples. Hundreds of miles away when looked
at the point of view of 5D is just an inch away (relatively speaking).
Is this possible. How many space dimensions is the minimum
for such to occur? What do you think?
R.


That's why GR is new to
me because I didn't think the Minkowski way before.
Another good concept to understand GR is the the spinning
disc where the outer rim spin faster and get distorted
and spacetime being similarly curvable. Don't worry. I'd
get a poster of Einstein soon and replace the one of Britney in
my room.

Well first you have to understand what he did. He did not simply write GR
in 5 dimensions - he did that and imposed a condition called the cylinder
condition. When he did that something called the Kaluza-Klein miracle
occurred - both 4D GR and EM popped out of the equations. But of course in
physics miracles do not occur - their must be a reason why it happened. The
reason has been found. GR is based upon general covariance. EM is based on
gauge symmetry. When the cylinder condition is imposed on 5D GR the left
over covariance turns out to be gauge symmetry. That is the origin of the
Kaluza-Klen miracle. Intuitively and leaving out the details (not always a
wise thing to do) the cylinder condition imposed the symmetry of a circle
which is basically what gauge U(1) symmetry is all about. Thus one could
argue EM came out because it was put in via the assumption of the cylinder
condition.

Because if its not,
then it should be made a basic fundamental concept due to its
sheer elegance.

It has trouble with QM.

And in addition to SR, GR as the definite concept..
I have to accomodate Kaluza Klein as a fundamental to
accomodate my world.

May I suggest before jumping to the conclusion it is fundamental you
understand the detail?

I mean there may be a higher symmetry wherein the principle of
relativity is just a subset. Why is symmetry the name of the
game. There must be a reason. The Minkowski geometry is
the one powerful enough for Einstein to use to describe
the curvature of space and time and he finally make it
compatible with the principle of relativity in 1915. It may just
be tip of the iceberg. That is simply what I meant.

he can get together with his lazy dog (which he called Einstein)
and the two can be fun to reunite.

I wonder why symmetries is abound in physical laws. And why
the weak force is somewhat an exception.. like what is above
them all. The more symmetries in the equations of physical laws,
the better and closer to reality compared to those with bad
symmetries.
Anyway. I have a question that lurks in my mind for many months.
C is the speed of light. The limit. matter is not supposed to
get lightspeed because mass and energy would become
infinite. Now faster than light hypothetical tachyons. It already
started as faster than light.. so not against the laws of
relativity. It can't be lowered to lightspeed because you'd
meet the same problems, more energy until it reaches
infinite. Now. My concern. Is it possible for a special
kind of boson to exist where it can couple particlesf faster than
light and below light. Imagine there is a particle
faster than light and a particle slower than light. They
shouldn't be able to contact each other because they
can't reach c. But what if nature has a special coupling
boson wherein it can couple them such that the particle
above c can affect particle below c. Is it 100% impossible
for such special coupling boson to exist or is it within
the realm of possibility (even how little) that it can exist???
Let's assume these special bosons are so rare and
the Big Bang just produced very little of them that
they are scattered across the universe in minute amount.
Never mind how humans can acquire these special
bosons. I'm just asking if their existence is 100%
impossible or within the realm of possibility....

study specifics. Penrose's book is a good place to start. Happy journey.

I wouldn't say relativity automatically debunks an aether. In the first
place is the difference between models of nature and our ability to know
the true reality of nature. We only have models, we can show whether they
correspond to observations. That's all we can do. In the realm of
electrodynamics, Lorentz's aether and Einsteins special relativity make
identical predictions-- how to choose?
Besides that, people on sci.physics seem to want an aether instead of
relativity, or an aether instead of quantum mechanics. But nothing rules
out a relativistic quantum theory of an aether. With the exception of
gravity in quantum mechanics and the exception of the quantum realm in
general relativity they are totally general theories of mechanics. The
standard model of particle physics is a particular model of interacting
fields to which quantum mechanics is applied. You can create a model of
an aether, or of interacting aethers, and apply quantum theory to it, if
you like. You can practice relativistic thermodynamics and fluid
mechanics, and then call your fluid an aether, if you like. Around here
on sci.physics aethers are used to try to explain why relativity seems to
be true when it's really not, but they're not mutually exclusive concepts.

I wouldn't say relativity automatically debunks an aether. In the first
place is the difference between models of nature and our ability to know
the true reality of nature. We only have models, we can show whether they
correspond to observations. That's all we can do. In the realm of
electrodynamics, Lorentz's aether and Einsteins special relativity make
identical predictions-- how to choose?

Besides that, people on sci.physics seem to want an aether instead of
relativity, or an aether instead of quantum mechanics. But nothing rules
out a relativistic quantum theory of an aether. With the exception of
gravity in quantum mechanics and the exception of the quantum realm in
general relativity they are totally general theories of mechanics. The
standard model of particle physics is a particular model of interacting
fields to which quantum mechanics is applied. You can create a model of
an aether, or of interacting aethers, and apply quantum theory to it, if
you like. You can practice relativistic thermodynamics and fluid
mechanics, and then call your fluid an aether, if you like. Around here
on sci.physics aethers are used to try to explain why relativity seems to
be true when it's really not, but they're not mutually exclusive concepts.

have ever read anything Lorentz actually wrote. His term for
time dilation was 'local time', that which is measured BY clocks
in moving systems. This is WHY! LET is identical to SR in its

Let's settle this the Riemannian way...
I know the basic concepts of GR theoretically

about geodesic, how non-Euclidian is curve and its
the geodesic between two points is arc of a great
circle.
Now when you put time in the 3D coordinates producing
a Riemannian geometry, the following is how I see it. When
I'm stationary in space and no gravity. There is only
movement in the time coordinate. When there is
gravity. This forces my world-line to become a curve.
When I am standing in the third step of the stairs.
The mechanical resistance of the floor is holding
against my continuous physical acceleration but
preventing my free falling in spacetime. When
I jump down the stairs. I continue to move in
spacetime but take a geodesic (which is the
"straight" version in Riemannian). This attributes
to my being attracted to the ground by "gravity".
I imagined this last week when doing daily activities.
I thought it is literal and my senses just can't

is just a mathematical model. This shakens me
and I therefore ask which of it is real and mathematical.

Your writings do not support that.

It ties to reality exactly the same way Euclidean geometry ties to reality.

Is it literal that points have position and no size? It is exactly the same
way what you are imagining is literal eg are you really a point on a
space-time diagram? Or is this a model you carry around in your mind?

and my senses just can't
perceive them. But Hoppa emphasized the above
is just a mathematical model. This shakens me
and I therefore ask which of it is real and mathematical.

Again I ask you in Euclidian geometry what is real and what is mathematical?
Think that though and you will have your answer. Hint - Euclidian geometry
is a model you carry around in your mind - you provide the links to reality
ie what you consider can be treated as a point. That is part of the human
activity of abstraction. But issues like that are for philosophy - not
physics.

It is ok
if it is for the sake of illustration. But then suddenly Relativity
is claiming gravity can indeed result from the 4D coordinate
mathematical model. It was just mathematical to add time
to space dimensions, suddenly it becomes real. Last week
I thought that relativity Spacetime indeed occur in 4D and the
limitation of our senses make us perceive space and time as
separate entities. But then you said it's not true and its just
mathematical. This starts the problem of wondering what is
mathematical model and what is real.

Four space lets us with some degree of accuracy equate
a volume of imaginary space-time with mass and energy.
The calculations work out but it is an imaginary space sort of
like Hilbert space where probabilites are mapped spatially.


As an illustration. You have 3D dimension of length times width
times height. Someone then tell you to add say the human heart
into the 3D coordinate to make up space-heart. This is then used
to explain how the heart pumps blood to the body. So what
I want to know is what is the physical basis of relativity
wherein time can indeed slow down and gravity occurs.
Gravity is attraction of our mass to earth or between bodies.
What has time got to do with it.

Untill the looser of a drag race crosses the finish line
with less fuel than the winner, you may assume
time and energy are inseprable.
http://en.wikipedia.org/wiki/Noether's_theorem


I justified it by saying time may have energy and it is
converted to mass at relativistic speed that's why time
slows down. It's like there is a certain maximum amount
of energy to every event. When you move fast, time slows
down because the energy of time is transfer to speed.

No... time doesn't slow down but an imaginary time is
useful if electrodynamics is involved... because of
retarded potential.

But you said it's wild speculations. So without
any physical model for relativity. I'm at a lost. Therefore I'd
like to know what it is.

Special relativity is:physically just the mass of
an electric charge and the Coulomb force:

Retarded potential. That is why Einstein only modeled
slowing clocks.
If you want a mechanism for gravity just assume all
bodies in the universe pull you in all directions equally
(inertia) and the earth spoils the isotropy.
You can pretend the force works like Van Der Waals
'till some supercomputer demonstrates that it really is. ;-)

Not bad. Not bad at all. Only thing is you are dealing in the parts and
not the parcel. The energy, so to speak, and not the synergy. You forget, I
think, the look of the entire distant universe at large as accelerating
expansionism. All that gravity which is everywhere whatsoever extant becomes
remotely communal overall, so to speak, as well as locally individual (so to
speak). A draw -- or attraction -- to the communal whole of the Universe is
a gravitational draw away from every single constituent individual making up
the whole. The first overlays the second throughout the Universe and is
dominant everywhere but most locally or gravity would be the strongest force
in the universe instead of the weakest and the Universe would cease to
exist.
The electro-magnetic and the strong-weak forces are dualities. So is
gravity a duality, the duality that doubles as "space" itself. Gravity's
attraction regarding the local-individual is universal. Gravity's attraction
regarding the remote-overall communal is multi-universal or attraction to --
rather continuously up through -- the so-called greater "Multiverse" or
"greater Universe." Thus there must be a finite limit to local gravity's
collectivism and mergers. An "inertial" limit. The overall collective of all
locals, or the overall merger of all, is already in place -- already in
effect -- in the infinity (in the Multiverse). That forever singularly
remote horizon, which at the same time is made up of every locality
everywhere situate, puts, or forces, an insurmountable drag upon all local
clustering and merger potentials. Very few can picture the exact same
gravity at once also being "anti" when being attached to a different frame
of reference (the overall frame of reference). The singular-duality, or
dual-singularity, of self-opposed character forms yet another, a third,
dimension everywhere: altogether the three-dimensional of volume, the
"void," the "vacuum," or "space."
Time is no more an add-on, or add-in, dimension to space than energy is an
add-on or add-in dimension to mass. "Real-time," simultaneous-time, is
equivalent to space the same as mass and energy are equivalents.
Distance-time is time to a certain point of some distant history (distant
place's past) via the ruler of the constant of the speed of light, not time
to any place, any simultaneity, in space whatsoever.
Astronomers tell us they are looking farther back in time the farther they
look out in space. To begin with, they aren't looking out in space at all,
they are looking out in time. Secondly, the farther they look out in time
the faster they say the universe's galaxies developed in time. Thus
inevitably they will reach a point in distant look into distance-time where
they say development of the universe via development of galaxies occurred so
fast that it occurred practically instantaneously in time. Following that,
they will then reach a point where they will have to say development
occurred faster than the speed of light. In other words, mindboggling
"speed" is everywhere at the other end of the universe from Earth. In other
words, mindboggling "speed" is everywhere at the other end of the universe
from anywhere and everywhere situate in the Universe whatsoever.
Acceleration existing everywhere between anywhere and that near speed of
light, or precise speed of light, horizon common, and constant, to anywhere
everywhere [in] the Universe (including common -- and constant -- [on] Earth
as well as [to] Earth). That acceleration away from any- and everywhere is
the [raised from the individual-local] physic of gravitational acceleration.
The developed galaxies there at the far end from us are not developed due to
any vastly increased speed of development but due to being in another
localized, but transparent, house in the greater Multiverse (the greater
Universe) than our own very localized -- but also transparent -- house.
There is no real continuity, no real continuousness (continuum), between
here and there. Between our own galaxy's history and that history at that
distance. Up to a point multiple universes (therefore multiple differing
histories as well) can and will be transparent to one another as well as
spatially reachable by advanced civilizations (largely thanks to the
[outward] draw, the outward attraction, and acceleration of infinity's (many
universes') gravity away from every local anywhere). Rather than one single
arrow of time, we are witnessing many points of many differing, paralleling,
arrows of time. A heck of a lot of more or less transparent "windows" into a
heck of a lot of houses other than our own. I like to think quanta dynamic.

No... I am only looking at distant induced-dipoles. Just
as atoms in your refrigerator door are aligned by a distant
magnet to produce an attractive force.

All that gravity which is everywhere

I only find gravity when there is some matter in the
neighborhood.

Time is no more an add-on,

There is no free lunch.

I didn't say that was the mechanism. A plausible
mechanism exists.
This is a plausible induction mechanism, currently simulated
to over ten orders of magnitude beyond Van der Waals
forces.
