Hello guys,
EMRP stands for electromagnetic radiation pressure.
The following are my replies to some discussions which I started up on
the sci.physics.research group, following one of my posts, regarding
the chances of compiling a fool proof push gravity theory. Strangely
enough, one of the moderators thought that the topic was highly
speculative,
even though he had acknowledged my first post in the first place!, and
so stopped my reply from appearing. So, I have forwarded my replies
here. Hope the same guys which
commented in the first place can comment further.
I have setup a section (in no way considered as final) here, so I
suggest reading it before starting to fire your remarks :

Here I have explained how electromagnetic radiation pressure can avoid
many of the pitfalls of older push gravity theories, and show how this
model can give us a working mechanism for gravity, something we do not
have yet. Comments are welcome.
Regards
Ing.S.Borg.

Thanks for all your replies, here are some comments. I do appreciate
all replies, and the fact that I am taking the opposition side, is
only for the fact that I believe this theory is too attractive not to
research it further, and possibly refine into something better.

"Gravitation cannot be shielded."
My comment:
Well, X-rays (~10^18Hz) are hard to shield, Gamma (~10^21Hz) require a
few mm of lead, Cosmic rays (~10^30Hz) peneterate though inches of
lead, so the shielding effect is all relative to what one expects from
his shield. At this rate, I wouldn't be surprised if one would need a
block of lead the size of Earth to get a measurable attenuation of
these gravity responsible waves if they are close to Planck freuqency
(7.4E42Hz), as I highly suspect. What I mean is that 'relatively no
shielding' is very different from 'no shielding', and we are not in a
position to state the latter yet. Also, we have a fair amount of knowledge for
Gamma frequencies of up to about 10^25Hz, but almost nothing is known
on the upper Gamma range which would theoretically extend to infinity,
though practically only up to Planck frequency. Also, the fact that
gravity does not repel, is a direct consequence of the radiation
pressure, which is equal to <S>/c, where <S> is the time averaged
amplitude of the longitudinal Poynting vector, which is a function of
[cos(x)]^2 and hence always positive.

"Perhaps it's just the observation that,
apart from rather speculative push-gravity effects, we don't seem to be
immersed in a bath of lots and lots of ultra-gamma rays? ...
Modern experiments on the falling of single cold atoms might be a
conclusive disproof, since radiation pressure due to ultra-high
frequency
radiation tends to be in discrete jumps; E=hf and all that. This isn't
observed.........while introducing severe difficulties related to the
exchange
of energy between the gravitational particle flux and conventional
matter. "
My comment:
In my opinion and of many others, that's opposite to what the Casimir
experiment proves. If we are not immersed in lots of ultra cosmic
radiation, there would be no force between the Casimir plates.
Also, in a recent experiment, researchers led by Valery Nesvizhevsky at
the Laue-Langevin Institute in France, isolated hundreds of neutrons
from all major effects except gravity, then watched them in a special
detector as gravity pulled them down. It was not a smooth fall! As
expected, if one considered radiation pressure, the neutrons fell in
quantum jumps.
Mie scattering and probably even some percentage of Reyleigh scattering
can easiely explain with our present knowledge on these 2 type of
scattering, the exchange of energy and momentum between an ultra high
frequency wave and matter. Mie scattering in fact eliminates one of the
biggest problems usually listed as one of the main objections of push
gravity, that is the excessive heat that matter would suffer from such
radiation.

My comment:
If we consider that the high energy electromagnetic wave packets
reaching the earth from all directions while it's orbiting around the
sun, then, the earth (and all other planets) will impinge on more
photons which are coming from radiation on its forward side than from
its backward side while moving around the sun and there would still be
a pressure imbalance due to the electromagnetic field imbalance due to
the doppler effect of the moving earth. This would resist the earth's
orbiting motion around the sun, resulting in the slowing down in its
orbit. (This is more or less what Feynman said). I am well aware that
most of the push gravity theories got stuck at this problem. This is
because it is always assumed that matter is acting as a black body to
all incoming radiation, including the ultra cosmic radiation
responsible for gravity. In these theories, bodies under the influence
of gravity would eventually boil to evaporation in no time and the
doppler effect would create enough radiation pressure difference to
create intense braking. However, if one assumes that the ultra high
frequency must have a characteristic wavelength equal to the
fundamental building block size of matter (a diameter in Planck
wavelength region), then, momentum transfer is successfully achieved at
a very high efficiency (radiation pressure coefficient QRP=2) by Mie
scattering mechanism, under which condition, there is literarly no
energy dissipation. The bandwidth of such frequencies for which this
occurs is measured as a fraction of the main frequency = df where
f~Planck frequency, or Bandwidth=delta(7.4E42Hz) which would be in the
order of 1E41Hz even for the most selective bandwidths (ie. ±0.1f).
This frequency band is in effect much greater than the doppler
frequency shift caused by motion of the earth in its orbital travel
around the sun. In terms of photon mechanics, the difference in number
between photons impinging on the front and photons impinging at the
back, will be a negligible quantity when compared to the actual huge
number of photons reaching the target from any other direction, and
they would still average to a virtually net zero force. It is easy to
see that the doppler effect, or impinging of photons whichever term you
like to use, would have only a negligible braking effect on any
relative motion, unless the doppler shift becomes so high as to
generate a frequency shift comparable to Delta(fplanck), which would only
be expected at relativistic speeds. Supporting this theory, we have in
fact evidence of this non-zero, still negligible dragging effect, which
will only result in a small but still measureable slow down of a
rotating system. It is in fact known that the rate of period change of
the binary pulsar system is about 75 millionths of a second per year.
As to aberration, you are mentioning 'particles' pushing, a condition
which I have strictly eliminated in the first place. The
electromagnetic push from radiation pressure is equivalent to
Einstein's tweaking of Newton's instantaneous acting law of gravity.
All experiments confirming Einstein's theory can be used to proof the
existence of radiation pressure effects.

S.Borg.
