assistant: The "nuclear winter" certainly contributed to the kill but I'm
 still waiting for you to support your insistence that the
 immediate blast effects did not result in a world wide fire
 storm and massive and deadly rise in the average atmospheric
 temperature.
If by this you mean Tunguska was not noticed at the antipodes of
course you are correct. However that event is commonly believed
to have been an air burst of a "house sized" object which is in
no way comparable to a "mountain sized" object such as we are
talking about in our overall discussion. My mention of Tunguska
was intended merely to report the very wide geographical
experience caused by a much smaller impact.

     The speed of light as a limit to the propogation of gravity waves is an
intimate part of the general theory of relativity.  There have been enough
tests of GR that the assumption of gravity propogation speed also being the
speed of light is pretty well verified.
     As for the other forces, they are local, not long-distance forces - I am
not sure how the speed of light relates to them.  However, since the strong
and weak nuclear forces have been combined together into a single symmetric
theory together with the electromagnetic force, I suspect that the speed of
light limit holds here as well.

     You can have creation events happen once (Big Bang style) or infinitely

     The thought that in a Big Bang universe that the total energy is zero is
a common one, and a definite possibility.  If that is the case, we are living
in an open, asymptotically flat Friedman-type universe.  It will expand
forever, but just barely.  The negative gravitational PE exactly cancels out
the positive KE of the mass.
     Why would your radiation have a black body distribution?  What does it

c (28 Apr 98  19:59:52)
Good question but a theory is hardly as good as direct measurement
even if it has a very good record of predicting things. People also
believed the Sun went around the Earth at one time and made it dogma
for it made more common sense in everyday life.
A theory, even a good theory should be revised when a better one comes
along. Because Einstein didn't like quantum mechanics doesn't mean it
was invalid and as we came to learn it can explain many more things.
A theory of quantum gravity is likely to bring some big surprises.
As fas as I can tell, experiments have been made which show a
variation in c. Not a great variation but some. Therefore I'm not
willing to pass judgement on either side until all the facts are in.
However, I'm still ammenable to accepting any new facts.
You see, in the previous message Sid simply quoted dogma without any
idea of his own. Science isn't about dogma, it is about ideas and
ideas marked with one's personality are the best ones to run with.

Re: Are atoms expanding? [1/2] (29 Apr 98  17:36:20)
It's just a simplification to assume c then was the same as now and it
may result in solutions being off by perhaps an order of magnitude or
more though still accurate enough for general purpose.
For example the uncertainty principle tells us that quantum effects
limit the ability to locate the event horizon on scales smaller than
the Compton wavelength. Spacetime then would have had a step-like
consistency or as Wheeler put it, "foamy".
At the BB a particle would necessarily have a wavefunction that must
fit into a very much smaller distance because particles then were
separated by distances comparable to their sizes. If the light travel
time of that distance is shorter than Planck Time then the value of c
would have to be dissimilar from our standard value. Spacetime was
nearly infinitely curved and c then had to be different from c now.
Today the only remaining objects that approach infinite spacetime
curvature are neutron stars and blackholes. So variations in c, if
any, should be more likely found near these, and which recent
observations are perhaps hinting at.

assistant: And which experiment would this be? One credible experiment
 showing a variation on the speed of light would be front page
 news indeed. Even an "incredible one" (witness the fuss made
 over "cold fusion") would have been widely talked about and I do
 not recall a single word on the subject. However I'm more than
 willing to hear about such an earth shattering and theory
 busting result.
 I find this comment highly offensive. "Dogma" is a matter of
 "belief" and has no place in science. The theory of relativity
 is a scientific theory in every sense of the term. It is
 supported by experiments making confirming measurements on all
 scales from the atomic to the cosmological. It has repeatedly
 made successful predictions of the results of future experiments
 since its original formulation.
 Science is not "about ideas" and even less about "ideas marked
 with one's personality". Rather it is about hypothesis and
 repeatable experiment. I can have the "idea" that the Moon is made
 of green cheese but that does not make it a scientific concept.
 It becomes a scientific theory when it is used to predict the
 result of an experiment (eg. If we dig up a shovel full we will
 be able to make a sandwich of the contents) and it is
 immediately comsigned to the scrap heap of science and loses its
 status as a viable theory when the shovel fails to turn up cheese.

Write your reply.

assistant: I was gonna mention that.  A few years ago in (I think) SciAm
there was a sidebar showing a model of this.  Apparently the
west coast of what is now India was roughly on the opposite
side of the planet from the Chixhulub <sp?> site.  The model
showed the impact shock wave going 'out of focus' as it spread
concntrically, but as it passed over to the other hemisphere,
it came back _into_ focus.  IIRC, the Deccan Traps cover much
of western India, and are believed to have belched on for as much
as 500K years.
Since the K-T object was likely 5 - 10 miles in diameter, it was
larger than the thickness of most of the atmosphere, and traveling
at some ungodly speed.  Therefore, there is nothing implausible
about impact debris splashing far beyond the atmosphere and
raining down elsewhere on the planet.
We tend to forget that altho the earth is 8,000 miles in diameter,
90% of the atmosphere is below about 30,000 feet, or about 6 miles.
