Me thinks you need considerably more mathematics to flesh your ideas
out into a real theory.  I would suggest the use of a self similar
(that is fractal) distribution of black hole sizes; interesting 
results might then drop out of the mathematics.  

Actually, the apparent ubiquity of black holes (in quasars, in AGNs,
in some galaxies, maybe even the milky way) makes me wonder whether
there might be some sort of primordial black hole component to the
universe.  With the right size distribution these primordial holes 
might account for missing mass and provide nuclei for galaxy 
formation.

P.S aside to Tom VanFlandern: You waited too long to publish 
your meta theory!  You've been scooped by Steve ! :-)

Because of the moon interfering with the viewing, there probably is no good
night this year. However, I believe the peak is August 10th. I am certain
someone will correct me if I am wrong.

It is possible that there will be a higher than usual shower this year, due
to the expected return of Comet (Swift-Tuttle?).

This morning 07/30/92 Lawrence Livermore Lab launched their second guide star.

This laser star is used as a reference by which the atmospheric turbulance
can be measured and hence corrected while photographing deep sky objects.

A laser at 5896 nm of about 1500 watts CW is shined straight up. This wavelength
is at the atomic sodium resonance. Its yellow, bright near the ground due to
air particles and fades off due to Rayleigh scattering as you look up,
 several moon diameter from this end is the star. 
The star is usable in a small radius about the launch sight.

The original estimates of the star brightness
 at 5 KM from the gound base sight was 14 Mag. 
I think I could see the star by eye.! So its at least 6 th Mag.
It appeared as a line, about a moon diameter long. I could definetly 
see it through 7-35 binoc's. --

                /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\

VALID UNTIL: 19:00 UTC ON 24 JULY

MODERATE RISK PERIOD: 22 - 23 July (UT days)

POTENTIAL MAGNITUDE OF MIDDLE LATITUDE AURORAL ACTIVITY:  LOW - MODERATE

POTENTIAL LUNAR INTERFERENCE:  LOW, BECOMING MODERATE AFTER LOCAL MIDNIGHT

OVERALL OPPORTUNITY FOR OBSERVATIONS FROM MIDDLE LATITUDES:  FAIR

AURORAL ACTIVITY MAY BE OBSERVED APPROXIMATELY NORTH OF A LINE FROM...

        NORTHERN WASHINGTON STATE TO NORTHERN IDAHO TO CENTRAL OR SOUTHERN
        MONTANA TO NORTHERN SOUTH DAKOTA TO CENTRAL OR SOUTHERN MINNESOTA TO
        WISCONSIN TO MICHIGAN TO NEW YORK TO SOUTHERN MAINE AND POSSIBLY
        PARTS OF NEW HAMPSHIRE.


SYNOPSIS...

     Auroral activity has increased in magnitude over the last six to twelve
     hours in response to a high speed solar wind stream emanating from a
     large and well placed solar coronal hole.  The stream is expected to
     maintain present levels of auroral activity for approximately the next
     24 to 36 hours before beginning to subside.

     Conditions will be moderately favorable for observations of auroral
     activity prior to moonrise near local midnight.  Thereafter, lunar
     luminosity will begin to interfere and hamper attempts to view activity.

     Most of the activity should remain confined to the northerly middle and
     high latitude regions.  Polar twilight over the high and polar latitudes
     will also hamper attempts to view activity over Northern Hemisphere
     regions.  Other areas which may be able to spot activity under dark
     skies include southern Australia, southern New Zealand, the northern UK,
     northern areas of Europe and areas of northern Siberia.

     This is not expected to be a significant auroral event.  No low latitude
     observations of activity are expected.

     This watch will remain active until 19Z on 24 July when it will either
     be updated or allowed to expire.

There are several papers which argue that by fitting the X-ray background
with the bremsstrahlung of the intergalactic medium it is possible (in
principle) to get the IGM temperature and density.  Some of the papers
which include arguements on both sides of the fence for this are

1)  IAU Symposium from 1990, The Galactic and Extragalactic Background
Radiation.  The article I read was by G. Setti on page 345.

2)  from the book _Physical Cosmology_, 1991, I read an article on
p 501 by Rodgers and Field.

3)  1988 Symposium entitled _Gauge Theory and the Early Universe_ has
a short article on page 367 by Barcons.

That is the "proximity" or "inverse" effect; the closer you get to the
QSO, the more ionizing flux there is to begin with, so the optical
depth to subsequent Ly-alpha absorption drops.  It makes it look
as if there is no gas near the QSO when, actually, the gas that
is probably there has been ionized already.  In other words, think
of "Stromgren spheres" around QSOs.  If I'm making this discussion more
optically thick than it already is, try referring to Weymann, Carswall,
and Smith, 1981, Ann Rev Astr Ap, 19, 41 or Bechtold, 1987, in _High
Redshift and Primeval Galaxies_, eds Bergeron, et al., (Singapore:
Kim Hup Lee Printing Co.), 397.  The first article is, I think, where
the term "inverse effect" was coined, and the second is a great
review-type article.

     To me, cool for supermassive stars means < 10 K or so.  [I assumed you
meant T = 1 K in the above.]  That would agree with the observed line widths
and other features.

     What I have hypothesized is an extension of the H-R diagram into the
higher mass region.  At first, this extension produces intrinsically brighter
and hotter supermassive stars.  Later in the extension, the increased opacity
and redshifts make the supermassive stars cooler.  This may or may not
connect with an extension of the existing red giant branch of the H-R
diagram.  The upshot of this is that some QSO's will be X-ray sources, and
some not, just as observed.

     That conclusion is in conflict with the observation of great numbers of
intergalactic hydrogen clouds between us and several nearby quasars, such as
3C273.  One easy way out of that conflict is if high redshift does *not* mean
great distance.  Then everything will be just as observed.  I don't recall
how you proposed to explain the lack of a monotonic relationship between
numbers of clouds seen in the Lyman alpha forest and redshift.

     I have now prepared the comparative list of quasar properties I
promised.  See the new thread "Quasars: near versus far".  -|Tom|-

A couple of sources give 5 p.m. CDT on Aug 11 on the peak; by my own calcula-
tions (based on Cook), it's 2 a.m. on the 12th. Despite the nearly-full moon
(whose presence would normally discourage meteor-watchers, the possibly
proximity of the parent comet P/Swift-Tuttle, might produce a higher number of
metoers, and hence a higher number of meteors bright enough to see despite
the moonight.

I recommend facing east (on a chaise longue, ideally) as soon as darkness 
falls; then turning southward a bit (45 degrees?) after midnight (since
you don't want to look directly at the radiant).

Go back and read the original article.  Only 3 of those 48 people were in the
engineer course.  The others were in other courses ranging from calculus-based
physics to physics for the brain-dead.  I would be interested in knowing
exactly how many there were in each course, rather than just the 168 person
total.

Look at Dearborn, D.S.P. 1992, Physics Reports 210, No. 6, 
pg367-382.

This is a review article on isotopic ratios of the CNO element group.
They calculate some theoretical values of N15/N14. They also give
values for O18/O16, O17/O16, C13/C12, both theoretical and observed
in red giants.

There has been a rumour floating around that the asteroid Toutatis
is going to be coming very close to the EArth.  Q.  Is there a
likelihood of somebody posting an updated ephemeris? Please?
Yours in anticipation.

Try Astronomical Algorithms by Jean Meeus. It has what you seek.
