<DIV><FONT size=2 face=Arial>Since some of you are interested in
gravitation, I decided to bring up another old (twenty years) mathemetical I
did. Newton's "Shell Theorems used his new Integral Calculus to prove that
INSIDE a large object (such as the Earth) there is often NO gravitational
field since the Force Vectors often exactly cancel each other out.
Since the Sun contains virtually all the nass in our Solar System, Kepler had
been basically right in his calculations for the Solar System.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT size=2 face=Arial>But ever since then, ALL astronomers ASSUME that is
also true of the Milky Way Galaxy. But the mass in the Galaxy
is really spread out so Newton's Shell Theorems prove that Kepler's math CANNOT
apply to the Galaxy. So a lot of the estimates reegarding the Galaxy are
probably wrong, being based on Kepler's simple formulas.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>In any case, this all got me to thinking that we
need to do massive numerical Integrations in the Galaxy, of Newton's
gravitational Vector equation.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I spent many months in doing math regarding our
TAPERED Spiral Arm (ours is called the Orion Arm). We happen to be very
near the inner edge of our Arm. There is not really much mass INWARD of
where we are for several tens of thousands of light years, but we have
MANY nearby neighbors IN our Arm. The Sun and Earth are therefore being
accelerated toward the centerline of our Arm, and this must forever be
true. I did another massive math problem and I found that we must "weave"
back and forth across our Arm, with a cycle period of around 52 million
years.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>THIS seemed interesting. We are currently
about one-fourth cycle more, or 65 million years from having passed through a
VERY congested centerline region, where we also were passing lots of stars and
objects which were "going the other way" being half cycle different from
us.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>At that time (1997), it was known that the KT
Boundary Event had happened 65 miillion yeara ago.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>My logic and math also predicted thatwe passed
through that same congested area 91, 127, and 39 million years ago. In the
years after 1997, there were other mass extinctions which happened at those
times. Is that an amazingn coincidence? I don't think so, and I
believe that there is a "gravitational explanation" for the mass
extinctions.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I also had noticed that the Southern Hemisphere of
the Moon has many more impact craters than the Northern. This is also true
of Mercury and Mars. At the time, I wondered of the Solar System was
"severely tilted" where the couthern hemispheres of everything "led" is through
the cluttered Arm centerline zone.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I recently discovered that Cornell University has
determine that our Solar System is tilted by 63 degrees from the plane of the
Galaxy. This might seem promising.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>Everyoone has assumed that the crsters on the Moon
are more than 4 billion years old. I am now wondering if most of them
might be very young, 13 million years old. I have asked Cornell as to the
ORIENTATION of our tilt in the Galaxy. It might be that they have proven
that our Southern Hemisphere(s) led us through all that debris at the Arm
centerline, so I am awaiting their response.</FONT></DIV>
