<p>Hi Chip,</p>
<p>I have found a paper from S. Carlip <font size="-1"><span style="font-size:19.925px;font-family:serif;"></span></font>which
is published in a publication of CERN. You can find it via the
link</p>
<p><a rel="nofollow" shape="rect" class="yiv3799900511moz-txt-link-freetext" target="_blank" href="http://cds.cern.ch/record/401893/files/9909087.pdf">http://cds.cern.ch/record/401893/files/9909087.pdf</a><br clear="none">
</p>
<p>This paper also refers to the paper of van Flandern. The paper of
Carlip presents a velocity dependent component of the force
vector. This is deduced for the electric field by Maxwell's
equations and special relativity (which essentially means the
same). For the gravitational field by the use of general
relativity. - This velocity dependent component can also be
understood by imagination if we understand a field as a stream of
exchange particles. This latter case is easily understandable if
we are willing to accept an ether as a medium. Because for the
propagation in an ether there is generally no aberration.</p>
<p>BTW: Einstein has once stated that the existence of aberration of
light (as visible in astronomy) was for him the most convincing
fact for rejecting an ether. This was at a time when Einstein did
not accept light to be a stream of photons. For the latter case
there is no conflict between an ether and aberration of light (as
particles).</p>
<p>Thank you, Oliver Consa, for the literature. And thank you, Al
Kracklauer, for your comment, I shall come back to it.<br clear="none">

<p>Hi Wolf, hi All, </p>
<p class="yiv3799900511MsoNormal" style="">some
time ago we had a discussion here about gravity. In particular
about the question whether the propagation speed of the
gravitational field is <b>c</b> or infinite. The problem
behind is the fact that a finite propagation speed of gravity
should cause rotating pairs of stars to permanently increase
their speed, because the other star appears at a retarded
position and so the force between the stars should have a
tangential component. Our discussion ended at that time with
the result that the Liénard-Wiechert potential would solve the
problem.</p>
<p class="yiv3799900511MsoNormal" style="">This
was not very satisfying because the Liénard-Wiechert formalism
is only about the field at a retarded time, and this
description by itself does not solve this problem. I found
that the solution is a completely different phenomenon. It is
the fact (and as such well known in the physical literature)
that fields like the electric field and also the gravitational
field (our case) never show aberration. This is – according to
literature – a well-known fact which is also theoretically
well understood. But most are not aware of it, like me. </p>
<p class="yiv3799900511MsoNormal" style="">Experimentally
it can in the case of the electrical field be proven in the
laboratory. And the motion of stars show it for the
gravitational case. </p>
<p class="yiv3799900511MsoNormal" style="">Do
you feel that this helps?</p>
