Steady State (02 Apr 98  17:12:12)
One idea is that symetry breaking was responsible for the creation of
the universe at the moment of the Big Bang. The conditions for this to
happen freely no longer exist. It was demonstrated that even radioactive
decay is sensitive to CPT.
The only known way to create matter today is to put a lot of energy into
an accelerator however the problem is that it also makes an equivalent
amount of anti-matter and the two kinds promptly anihilate one another.
No protons are being created in the universe today. The energy level is
much too sluggish compared to the BB at t = 10^-43. Figuratively
speaking, all the fizz has left the pop bottle.

Write your reply.

assistant: Well, I've just come across some interesting news relating to what AGG
said was my "ad hoc" explanation on whether atoms are expanding:
The fine structure constant is a dimensionless ratio relating the
electron's orbital velocity to the speed of light. If this value was
significantly different, a lot of our biochemistry would be different.
This value is roughly about 1/137. This ratio however varies with
changes in momentum and of course with changes in the speed of light.
Of interest with the latter is that the speed of light can change in the
presence of strong electromagnetic or gravitational fields as stated by
QED. This effect was in fact observed in the 1930's. The effect is
negligible on the Earth or even near the Sun but it is appreciable near
neutron stars and BH's which have enormously intense fields.
Now the above report states that this constant is tied to the arrow of
time. Since we know that time flows at different rates this means that
the fine structure constant was different in the past or in other words
in very distant objects and atoms may in fact be a different size there.

assistant: If you don't understand the math, you don't understand the problem, and
therefore have no right to an opinion on the subject.
Sure.  Kinetic energy E(k) = 1/2 m v^2 in a Newtonian framework, where m is
mass in kilograms, v velocity in meters per second and energy comes out in
Joules.  Nuclear explosive power is gauged relative to the explosive power of
the chemical explosive, 2,4,6-trinitrotoluene (TNT).  A gram of TNT yields
4,200 Joules of explosive energy.  Say you want to increase, or decrease, the
velocity of an asteroid by a given amount, enough to miss the Earth.
Let's say the asteroid is traveling at 30,000 meters per second, a
representative speed for Earth-crossers.  If detected on a collision course
from say, 10,000,000,000 meters away, and given that Earth's diameter is
6,378,040 meters (I'm using the equatorial figure), a velocity difference of
about 0.06% would be of the right order of magnitude to avoid hitting the
Earth.  More precise calculations would involve the asteroid's actual path
and the angle at which its orbit will cross ours, but we can leave that aside
for the moment.
Say the asteroid is 1,000 meters in diameter and roughly spherical, with a
density equivalent to that of surface rocks on the Earth (about 2,800
kilograms per cubic meter).  The volume of a sphere is (4/3) pi r^3, or here
about 5.236 x 10^8 m^3, giving it a mass of around 1.4661 trillion kilograms.
 With the velocity cited earlier, the kinetic energy is 6.5974 x 10^20
Joules.  A difference of 3.9584 x 10^17 Joules must be made in its kinetic
energy.  By the conversion factor cited, this is about 94 megatons of
explosive energy.
Assuming no conversion of the bombs into shaped charges, the efficiency of
transfer would probably be low, perhaps 10%.  Therefore 940 1-megaton bombs
would be needed.  Since we and the Russians between us have about 50,000
warheads available, many in that yield range, deflecting the asteroid is well
within our capabilities.

mode.  I'll try to calm down.
I think you're assuming above that the expansion rate has to be zero at the
moment of the Big Bang.  I don't think that's needed.  If you extrapolate
back the current expansion rate, depending on what model you're using,
everything fits together 10-20 billion years ago, which is evidence for the
Big Bang.

Old news. Tasco makes the Celestron 'First Scope'. Actually the theory
is that Tasco is a front for a cabal made of Celestron and Meade. They
let Tasco sell the trasco scopes, get the revenue from the sales. And
sit back and watch the hordes come crawling to them directly for real
and proper telescopes. And they collect revenue from these new sales,
too.

Well this is an astronomy echo, rather than cosmology, but there's a lot
in common.
Stephen Hawking writes well-known books, and is easy to get hold of
copies (A Brief History of Time, f'rinstance) but he's quite a
speculator and it's tought stuff for the novice. A better source is an
american lecturer who's name escapes me but will surely be mentioned by
others. There are quite a lot of books on the market with "black hole"
in their title, which tend to be good science as people after
sensationalism are put off by black holes. Avoid anything with the word
"pyramid" in the title, unless you are good at wrangling :)
Other good sources are (not surprisingly) reference books published
recently or online. For instance, the Encyclopedia Brittanica is
remarkably current and comes on CD rom. It has the added advantage of
being reasonably conventional and covers a whole load of things on top
of cosmology.

ASTEROID PASSING CLOS (05 Apr 98  06:15:04)
Under the old (Dr.Strangelove) doomsday philosphy of MAD (Mutually
Assured Destruction) each side had something like 1,000 times overkill
(before SALT and SALT-II). The then best cobalt devices were in the 60+
megaton range.
Today's state of the art probably double or triple that old figure. It
thus requires much less than 940 devices. Maybe 10 or so. However, quite
obviously it's much too risky to launch such a dangerous payload. The
safer solution is either solar powered ion engines or atomic rockets.

	What Barton is referring to is known as "Olber's Paradox."
 No difficult calculations required, just the realization that the
 intensity of light fades only with the square of distance, whereas
 the volume of space increases with the square of distance.  Yes,
 stars will appear dimmer with distance, but the increased number
 of stars will more than make up for this.
	New stars are also being created.  And the greatest number
 of stars are white dwarfs, which have a lifetime greater than the
