Sure it does, that's why the big bang is a big bang. It has to be a
massive outpouring of energy in order to still be expanding all these
years later. The whole hubble value thing is based on the assumption
that the universe has been expanding since the big bang at a gradually
slowing rate. In reverse, the expansion is faster and faster as you
approach the high speeds of the early periods.
To find that expansion is speeding up invalidates the model entirely.
Here's the analogy. If you draw a graph of arctan(x), by measuring the
curve at some point and inferring the curve of arctan(x), you discover
that at the origin, you tend towards a vertical line. This would be the
very hot and very dense big bang, implied by the curve and the present
slope angle. You calculate the position of the origin relative to where
you are now and derive an age, and then you go looking for secondary
evidence to support your theory that the graph tends towards a vertical
line at the origin.
However, if you find the curve is going the wrong way, a completely
different curve emerges, and you no longer have the vertical line at the
origin. In fact, you might end up with a curve which tends towards zero
at the negative maximum, i.e. a horizontal line.
Someone might want to work on that analogy for me, it doesn't sound very
visual. :)

assistant: You are assuming:
A)  That all the energy is thermal energy.  This is incorrect.  Some of it
will be released as visual energy and TV-wavelength, and this will leave via
the atmosphere, which is transparent to those wavelengths.  Some will go into
mechanical deformation of the material at the impact point.
B)  That transmission of heat to the atmosphere is perfect.  You haven't
accounted for optical thickness or water vapor content, both of which are
likely to be extremely high in the vicinity of the blast.
C)  That the energy just kinds of stays there.  A lot will radiate away as
the heated air expands (and of course the energy of expansion will also take
some energy).
I reiterate that the air antipodal to the impact will not be significantly
heated.

     A simpler method uses surface pressure times the surface area of the
Earth.  This gives you the weight of the atmosphere, and thus the mass.  Now,
there is a small change in the gravitational constant as altitude increases,
but this effect is minimal.  The errors introduced would be less than the
approximation you used.  So, with a pressure of 101,300 Pa, an average radius
of 6370 km, gives a weight of 5.2 x 10^19 N, or a mass of 5.3 x 10^18 kg
(about one millionth the mass of the whole Earth).  Using your energy values,
the atmosphere of the Earth would be raised by an average 135 degrees,
assuming isotropic distribution, no cooling, no external sources of heat,

The current thinking on the problem is that the expansion may not have
been smooth. It may have gone through periods of so called
superfusion. For example a common case of superfusion is when cooling
water rapidly, it's temperature can drop below the point of ice
forming and yet remains in its liquid phase. Then after some time it
eventually freezes into the solid form and the volume expands.
This sort of idea is thought to have happened in the period after the
BB as the expansion may have stopped momentarily while the
temperature/pressure went past such a change of phase state where
reactions may have had to absorb energy before the expansion could
resume. Thus plotting the expansion vs time would show sharp spikes
and dips corresponding to when the phase transitions occured.

Re: Big Bang (16 Apr 98  12:43:00)
Some people have suggested that the uncertainty principle may not be
quite so uncertain only that we haven't figured it out yet. Recent
experiments in photon entanglement have in a way hinted at this. You
can take a quantum event out of its environment but you can't take the
environment out of the quantum event.
To an outside observer, a perfectly coded transmission will seem
indistinguishable from the background noise and is therefore
undetectable. The message of the BB may be like this. Note that we've
only of late discovered the CMBR and very recently the IBR.
In fact the CMBR discovery started out as a nuisance noise factor in
Penzias' and Wilson's communications experiment. In hindsight it seems
quite fitting that if there is a BB message it would show up in a
communications experiment.
