<DIV><FONT size=2 face=Arial>Yes, if the Milky Way is fifteen billion years old
and if the Solar System resonates around every 50 million years, it would
logically seem that we have done around three hundred cycles so far, and so we
have passed through the cluttered centerline are around 600 times so far.
I am not sure what the implications of this are. But the most recent time
we passed through there was around thirteen million years ago, and my
calculations are that the "southern side" of the solar system must have led us
through, which is why I suspecxt that the southern hemispheres of the Moon and
Mercury and Mars might have a logical reason for having so many
craters. No one elae seems to have ever cared about this geometric
anomaly. An impliction might be that the craters on the Moon might NOT all
be 4 billion years old, but some or many might only be thirteen million years
old, mere pups. We are not likely to try to land any spacecraft near
Copernicus, so we probavly will not get any geologic samples from the big
craters to try to date them.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I am not sure I can buy the "massive"
argument. It seems to me that in <FONT size=3 face="Times New Roman">1919,
the Einstein calculations for the solar eclipse was a decent fraction of a
degree of apparent bending, even substantially away from the Sun's edge.
We are talking about REALLY TINY fractions of a degree, even tiny fractions of
an arc-second at the distances of an Einstein Cross. I am still not
willing to just adopt the Gravitational Lensing reasoning, but somebody should
do the math to see just how much mass might be needed to produce the observed
bending. My guess is that it would be fairly minimal.
</FONT></FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>Yeah, you might have a brilliant insight that the
differential density of the Corona might actually be the cause of the observed
refraction, and Einstein might have been wrong in crediting GR. An
interesting subject, where known numbers might confirm or deny your idea.
And, if so, also as you mention, apparent gravitational lensing effects where we
do see refraction. </FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Yeah, the tip is trailing. Think about a
hundred million equal mass stars, and billions of years, where an initial
velocity existed. Not only doea the Sun and everrything else weave
crossways, we are also being (slightly) attracted forward by gravitation of
maybe 70 million stars which are in the wider part ahead of us, ut we are
attracted rearward by the gravitation of the thirty million masses behind
us. I spent a couple years with a computer in the late 90s to try to see
what might happen. The tapered shape forms, with the wider and more
massive amounts up front, and where the "trailing" stars may either get lost out
of the Arm (due to lesser available gravitation) or some might get pulled
forward to populate the forward wider part. Every computer simulation,
even with just a thousand identical masses eventually formed a tapered
shape. And for the very tail, we have all hundred million gravitational
masses pulling it forward. My web-page refers to a bunch of ice skaters in
a "crack the whip" handholding pattern (gravity) where the very outermost skater
zooms at superhuman speed, but is slightly curved behind the people just alead
of him, causing the CURVE of the "whip" or the Arm.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Those few stars at the veery, very tail have really
minimal gravitation affecting them, nearly all nearly straight forward (like the
hand holding of the whip). And individuals might also get lost, making the
tail get narrower still. A cool part is that pure newtonian gravitation
thereby causes the tapered shape of every spiral Arm. AND it assures that
they are STABLE.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Except in rare cases of anomalies like <FONT size=3
face="Times New Roman">M51, where "the hand holding failed part way out" and so
M51<BR></FONT>has a "ball" at the "tail" of one Arm. I feel that the total
of the two Arms in <FONT size=3 face="Times New Roman">M51 have similar masses,
where the "ball" has made itself into a ball (possibly fairly recently, a few
billion years).</FONT></FONT></DIV>

<DIV><FONT size=2 face=Arial><FONT size=3 face="Times New Roman">Are my comments
adequate? I will try again if they are not clear. I also want
to note to the Group that I am old and have severe Parkinson's, so my fingers
sometimes double key some letters for spelling errors.
Sorry.</FONT></FONT></DIV>
