  and come to think of it, so are pieces of bread left

  Hummm... Now that I think of it, as seen from space,
  the earth and evything on it is related to astronomy.

assistant: Hi,
[..]
 Thankyou for you explaination, I know I'm thick but that one got through to
me.
 I don't quite see the relevance of the increase in size of individual
objects as part of the equation though. We are not increasing in size and I
have seen no evidence to suggest that objects far away from us do so either.
 In spite of that I can see what you are saying, thanks.
 Now you done gone and spoiled it :-))
 You have now accepted the possibility that some
objects, relative to us may have
 exceeded the s. of l. and consequently relative to us  have infinite mass
(plus).
 Now I have been told again and again that the s. of l. cannot be exceeded.
?

assistant: Depends on what you mean by "aligned". Most of the planets will
 be in the same part of the sky as the Sun around that tim spread
 out over about 20 degrees or so of sky. If you hold your
 clenched fist at arms length that covers about 10 degrees of sky
 so they will all be inside about "two fists" of sky. Because
 they are all close to the Sun in the sky we won't get to
 actually see this nifty sight. The "alignment" is of esthetic
 interest only and the reports that you may have already seen in
 the sensationalist press or will certainly see as the time
 approaches about catastrophes which will be caused are pure
 garbage.

     I myself don't see it like that.  I do not hold the view that life
acausually caused the universe to be the way it is.  Rather, given an
infinite number of possible universes and possible values for the physical
constants, we should not be surprised at being in the universe we inhabit,
because we couldn't have been anywhere else.  The probability _may_ be
infinitely small that a universe with the proper physical constants exists,
but you only need it to happen once, and then we pop into existence and
marvel at our luck at being here.
     The argument may be a little bit circular, but it shouldn't be taken as
a cause and effect argument.  I think....  :-)

On 07 Mar 98, MIKE ROSS wrote to Arnold G. Gill:
     Actually, the curvature _decreases_ with time - the universe is getting
bigger and flatter.
     This pinged a memory of mine, a relationship between actual angular size
and observed angular size and its dependance on redshift.  In particular, the
distances determined by luminosity and angular size are related by
                d_L/d_A = (1 + z)^2.
So, for z = 2 (a moderately distant galaxy), the distance determined by
comparison of luminosities is 9 times the distance determined by the angular
size of the object.  Thus, for distant galaxies, the angular size enhanced
over its luminosity, which is what you have said, I believe.  This effect is
taken into account with all observations, though it is thoroughly muddled
because it cannot easily be separated from observational restrictions.

     But in order for the speed to be invariant, distance and time must vary
together so that the speed of light remains constant.  Then, any method
devised to measure distances would of necessity use both time and the speed
of light, which must still always give d = vt.

assistant: I saw that too.
I was wondering - if this is confirmed, what does this do to the
"Age of the Universe" questions?  Does it affect things at all?
I recall problems where one theory gave the age of the oldest stars
as being greater than the theoretical age of the universe.
If either of these calculations on age depended on having only
attractive forces, does the discrepancy go away?  Does it get worse?
Or does it affect both the same way?
If confirmed, it would seem to dim the chances of a Big Crunch....

assistant: Barton Paul Levenson said the following to Mike Ross on the subject of
Re: Big Bang (10 Mar 98  19:36:24)
Not necessarily...
There is always the possibility that the anisotropy has another
explanation. Being it is almost insignificantly tiny it may have
absolutely no connection with the present day clumping. Smoote had
previously been criticized about that.
Now it is even more likely his idea is undefendable since the newly
discovered Cosmic Infrared Background (CIB) is absolutely smooth
compared to the Cosmic Microwave Background Radiation (CMBR).
If anything the CIB map should show an even greater anisotropy than the
CMBR because it has a far larger intensity and would therefore be less
affected by other causes. It is in fact because the CIB is much stronger
that its great smoothness is so surprising. After all it was somewhat
expected to mirror the anisotropies seen in the CMBR.

assistant: Hello everyone, any luck fighting the clouds?  I lost.
     I dont have questions, but I need some...
 I've been doing public Planetarium shows for children, usually Cub/girl
scouts or even adults at St. Vincent College..
Anyhow, they have always left the show empty handed.  I want them
to have the option of picking up one or two little astronomy sheets.
One is a star chart of the major constelations.  The other is undecided.
Since they are primarily for children aged 9-13, I wanted to do some
kind of quiz, or factoid sheet, kinda like on Happy Mills..
 But I do not know what exactly to put on the sheet. Here is what I came
up with:
A little crossword puzzle,
Fill in the blank questions,
Random facts on numerous topics, (suggestions needed)
pictures comparing the sizes of stars.
Illistrations on Black holes, and Supernovae. (I coud cramm it in).
Our stars Birth, life, and Death,
Someone suggested a coloring picture.
        Anyhow, If you have done something similar, have suggestions,
specific questions, that a kid would be interested in, comments,
Ways to organize the sheet, complaints, or anything else, It would be greatly
appreciated if you reply.
I have found the kids to be especially interested in Black holes and
     Super Novae, SN remmenants, expecially Crab and SN1987A,  The
     constellation of Orion.
     (Yes, these 10 year olds suprise me with their knowledge!)
I have found them not to be instersted in galaxies, galaxy collisions,
     and other objects far beyond our galaxy (I dont know why).

the idea is that universes are constantly being created by whatever process

those that have constants much different from ours, life as we know it can
not arise.
If a lot of different universes are created, sooner or later one with
physical constants in the right range will occur.  Ours is the one being
studied because we're here to study it, and we're here to study it because
the constants "gelled" the way they did.

assistant: Harold Groot said the following to MIKE ROSS on the subject of
Expansion Increasing (03 Mar 98  23:02:00)
One, it means the curvature is saddle shaped and the big crunch is out.
Then there's a mention of a very tiny 5th force which works at the
nuclear level and which shows up as a repulsion of matter at the cosmic
scale. This could bring back the universal constant Einstein had
previously discounted.
As for the age, it may mean the universe is actually younger than it
appears since the furthest redshifts are greater than they would be if
spacetime curvature was flat. Which means the theories on star evolution
will have to be reviewed as well since the universe would be younger
than its oldest stars.
