ANY of that stuff has to do with 'g' as it is not [as far as we know]
electric or magnetic. Is there some particular gauge that gives us the
gravity metric, advanced, retarded or normal?




20. A. K. T. Assis, "Deriving gravitation from electromagnetism,"
Canadian Journal of Physics, Vol. 70, pp. 330-340 (1992). Abstract:
We present a generalized Weber force law for electromagnetism
including terms of fourth and higher orders in v/c. We show that these
extra terms yield an attractive force between two neutral dipoles in
which the negative charges oscillate around the positions of
equilibrium. This attractive force can be interpreted as the usual
Newtonian gravitational force as it is of the correct order of
magnitude, is along the line joining the dipoles, follows Newton's
action and reaction law, and falls off as the inverse square of the
distance.


http://www.ifi.unicamp.br/~assis/wpapers.htm



But gravity is isotropic [AFAWK] and all of my attempts to build isotropic
dipoles have flopped. [They keep falling over.]


*Induced dipoles* operate in any position. They automatically
conform to all kinds of variables.


That would seem to leave a bit of a black hole in their theory.

Webber almost makes more sense with his 'electrostatic attaction slightly
greater than electrostatic repulsion'. But anti matter shoots holes in
that.


I don't think you understand how induced dipoles work.

The clock mechanism is not specified so that it can relate to any
physical phenomena.. So I conclude it is actualy the article which
falls. )


I did think their building clocks with the 'specific gravity' of air was
interesting. I think they are sending up a trial balloon to see who is in
caloots.

What does maxwell/einstein say about two orbital clocks in counter
rotating motion in essentially the same orbital [we must assume they
miss each other].


Probably nothing. Maxwell/Einstein is about the forces between relative
moving particles so why should it talk about clocks?


BBBut, I thought AE went to a lot of trouble to talk about clocks....

I thought they were postulating some kind of virtual photons being emitted by
the dipoles and the coupling was drawing things together.

A quick read can be wrong.

If you think van der waals forces are enough to give us gravity, you should
be able to take the Van Der Waals gas law and the ideal gas law equations and
derive the force of gravity.

(p+a/v^2) (v-b) = RT and PV = nRT or RT = PV/n

so (p+a/v^2)(v-b)=PV/n ... hm not sure how to get g out of there.
a is the measure of attractive force between molecules and b is the effective
volume of one mole of gas.
a = v^2 (b n p - n p v + P V)/n(v-b)

If we assume v=V and p=P then
a = - p v^3/(n(b-v)) - p v^2

I still don't see g hiding anywhere there, but perhaps it is in de-skies.

see the equation following:
In the limit that áw kT the entire progression can be calculated using
They lost me in that last transform.

Depends on what kinda pets you have with you. You did mention snakes in
another post. I prefer turtles, myself.

One of the observations ...is that synchrotrons, tokamaks,
and other such devices can't seem to get particles going
past lightspeed, even when one pours energy into them far
in excess of what the Newtonian limit requires.

For example, m_p = the mass of a proton = 1.672 621 71(29) * 10^-27 kg,
according to

http://physics.nist.gov/cgi-bin/cuu/Value?mp .

1/2 * m_p * c^2 = 7.51638712 * 10^-11 J = 469.13602 MeV.

That's all the energy one needs to accelerate a proton to lightspeed --
in theory. (Newtonian theory, anyway.)

*Induced dipoles* operate in any position. They automatically

Fair warning: I only have a few weeks experience with this *mechanism*
so may not be able to answer with the certaintly I would like. Keep an
open mind and be prepared to do a little digging. Nearly every month
something related shows up on axriv so it isn't a dead horse.

"can be interpreted as the usual Newtonian gravitational force as it is of

I thought they were postulating some kind of virtual photons being emitted by
the dipoles and the coupling was drawing things together.


The best analogy I can offer is dipole-dipole coupling is like sinusoidal
waves in a shaded pole magnet.

Induced dipole to Induced dipole coupling is more like spread spectrum
waves because they can adapt to each other simply by squishing orbitals.


A quick read can be wrong.

That would seem to leave a bit of a black hole in their theory.

Webber almost makes more sense with his 'electrostatic attaction
slightly greater than electrostatic repulsion'. But anti matter shoots
holes in that.

http://www.chem.purdue.edu/gchelp/liquids/inddip.html


If you think van der waals forces are enough to give us gravity, you should
be able to take the Van Der Waals gas law and the ideal gas law equations and
derive the force of gravity.

(p+a/v^2) (v-b) = RT and PV = nRT or RT = PV/n


Not that simple. It is like having amperes law for a magnet (1/r^3)
but you need to reshape the Coulomb force as Maxwell and Weber
do to produce a very weak but attractive 1/r^2 force.

Think about radiation recoil/pressure as a repulsive complement to EM sine waves.

Think about gravity as an attractive compement to Electo-London SS waves.


so (p+a/v^2)(v-b)=PV/n ... hm not sure how to get g out of there.


The ratio of Coulomb force to gravity is huge. 10^32o 42 or sumsuch.

a is the measure of attractive force between molecules and b is the effective
volume of one mole of gas.
a = v^2 (b n p - n p v + P V)/n(v-b)


Remember the attraction between a pair of magnets gives little clue of
the repulsion due to radiation recoil/pressure.


If we assume v=V and p=P then
a = - p v^3/(n(b-v)) - p v^2

I still don't see g hiding anywhere there, but perhaps it is in de-skies.



http://chsfpc5.chem.ncsu.edu/~franze...hop/fc/fc.html


see the equation following:

They lost me in that last transform.


Indeed. Most evolutions end up with a page or two of EigenFokkers
and satanic symbols but I have found a few URL's with as many words
as musical notes and deposited [scattered ;-) them in the Electro London
thread.



There are no reports of London forces going on strike during a PET
scan.

It is no more snake oil than rockets under your chair and it does make a

300000000 m/s / 100 N/kg / (24 hr/day * 60 min/hr * 60 sec/min)
= 34.72 days. [Newtonian]

100 N/kg = just over 10 "g"'s. Fighter pilots can handle
about 10 g's head-to-butt, for short periods. One might
contemplate higher accelerations if stretched out, but
I don't know the maximum.

It wouldn't be comfortable.

As for time dialation:

http://hyperphysics.phy-astr.gsu.edu...s/muonatm.html

gives a point of data for the approximate energy of muons
reaching sea level of 4 GeV, and

http://hyperphysics.phy-astr.gsu.edu...ativ/muon.html

some theoretical calculations on survival calculations thereof.

Since the rest energy (m_mu * c^2) of a muon is 105 MeV, this
"proves" superluminal muons -- except that they wouldn't survive
to ground level as muons.
