<DIV><FONT size=2 face=Arial>I think we are on the same page, but I really
believe that Gravitational Lensing is POSSIBLE, although I do not think it is
due to any GR effects. My specific issue here is that geometry and logic
should seem to create "perfectly symmetric" patterns of images, same brightness,
same spacing, same spectras. When I have looked at claims of
Einstein Crosses, and very carefully measured the spacing of the images, I have
not seen any which really have precise spacing. I have not had access to
the spectra of the various Einstein Cross images, but some seem to just be
"really poor". </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>As to the basic CAUSE of possible Gravitational
Lensing, it may be beyond me. I look forward to anyone informing me of any
Einstein Cross which seems to be logically and geometrically impressive, to
confirm to me that the "phenomenon" is credible. Once that is the case,
bring on any arguments regarding mass and such.</FONT></DIV>

<DIV><FONT size=2 face=Arial>Mr. Hollings, you may enjoy a graphic in one of my

<DIV><FONT size=2 face=Arial>IIt is a sky map showing the locations of the Core,
the location 90 degrees away from that (as a potential direction our "sun
orbiting" might be headed in that <FONT size=3 face="Times New Roman">200
million year orbit), the ACTUAL direction our Sun is moving (XYZ), etc. I
used that info to determine the Z velocity of our actual sun's motion (currently
upward). I also combined the various velocities to determine our
components due to the Kepler gravitational effect and some other velocities we
experience within our Orion Arm. Around twenty years ago, I concluded that
our Solar system "weaves" radially across our Arm (partly due to the asymmetric
taper spape of all Spiral Arms, where more attraction is "ahead of us" and less
attraction "behind us" in our Arm. Other gravitational effects also exist,
all of which I credit to Newton, and NONE of which I credit to any GR. I
spent a couple years doing the newtonian gravitational attraction calculations,
and came to an estimate that one result is that we "weave" back and forth across
our Arm about every 52 million years (and we are currently near the inner edge
of it. </FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>No one has ever bought into this (yet) but those
calculations suggest that we pass through a very cluttered Arm center-line area
every <FONT size=3 face="Times New Roman">26 million years. I think it may
be a cause for the Moon and Mars and Mercury to have southern hemispheres which
are very pock-marked. And possibly bombardment on us on Earth 65 million
years ago which might have toasted the latest dinosaurs.</FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>Oh, the <FONT size=3 face="Times New Roman">200
million year sun orbit figure is mostly due to a (very weak) Kepler
calculation. It may be fairly accurate, but I am uncomfortable with the
logic in relying on Kepler for it.</FONT></FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>And people in this group seem to assume that I am a
"Relativity wonk". RARELY, I see enough logic to support some possible SR
or GR claims, but many of you guys seem to w ant to associate GR with far too
many things. I am currently composing a fairly brief discussion about SR,
which mostly denies almost all the issues it gets credit for. It IS valid,
but for some reason, nearly everyone seems to give even SR all kinds of
credit.</FONT></DIV>
