All we would need for our universe to be expanding would be for the

expanding at all but, because of the red shift, merely appears to be.
Consider: If, as a result of inhomogeneity in the cheese, matter is
being accelerated toward the wall of the bubble and is absorbed by the
bubble once it hits the wall, we will cease being able to detect it and
will see that boundary as the "horizon" of our universe. Also, if the
matter is sufficiently accelerated and goes luminal at some point we
will cease being able to detect the matter and view, instead, what
appears to be the horizon of our universe. Interestingly, if the matter
went luminal it would result in the emission of Cerenkov radiation which
we would percieve as the background radiation. On the other hand, if it
didn't go luminal, but merely smacked into the wall radiation would also
be emitted. In either case, radiation would be coming at us from
everywhere in the sky, as it does.

I have no problem with the bubble being in a state of expansion,
contraction, or stasis, any of the three being possible.

Not necessarily. Fish that live in the deep ocean have no inkling that
they're swimming around with a pressure of 10,000PSI all around them.

I'm not ruling out equal universal expansion, but at the moment I'm

There are undoubtedly groups where this material is on-topic, but I

Snip of not very interesting stuff
The belief in the existence of dark matter is a fallacy.
Suppose for a moment that our local universe is merely a bubble
surrounded by an infinite expanse of infinitely dense, infinitely
energetic Universe. For want of a better analogy, a void in a block of
Swiss cheese. When our universe was formed and the void appeared, some
of the material from the Universe outgassed into the void and eventually
became the matter from which everything in our universe is composed.
However, since the beginning of the formation of the void, the
gravitational force of the Universe has been attracting matter back to
itself. Because of the inverse square law on our side of the void wall,
the closer the matter gets to the void's wall the more it is attracted,
the greater its velocity will become, and the greater the red shift the
farther out we look. If the velocity becomes luminal, then its mass
becomes infinite, leaves our local universe and rejoins the infinite
Universe.
So, if this conjecture is true it would explain the reason for the
increasing red shift with distance, the discrepancy between how much
matter should be here and how much there appears to be, (obviating the
need for the existence of dark matter) and the reason for the horizon of
the universe.
It would also settle the question of whether our local universe is open
or closed. Interestingly, it would also bring up the question of
whether or not the Swiss cheese was really a black hole in which we were
embedded!

Very interesting theory. However: assuming that the hole in the "Swiss
Cheese" is spherical, and that the density of the surrounding "cheese" is
constant, which seems reasonable from the relatively constant amplitued of
the microwave background radiation, it has been demonstrated, frequently,
that the gravitational effects within such a spherical chamber are zero. In
other words the attraction of the surrounding grativy generating medium
actually cancels at any point in the surrounded sphere.
Yes, which means if my theory is correct either our bubble isn't
spherical, the surrounding medium isn't homogenous, or both.
---
---It follows from this that the atttraction of the surrounding denser medium
will have no effect on the surrounded volume, while the spherical "bubble"
exists. Therefore, matter and energy near the boundary of the "hole" will
not be affected by the presence of the surrounding denser medium more than
matter close to the center. There is no net gravitational effect which will
accelerate the matter within our universe toward the surrounding denser
medium. So, should such a super dense surrounding medium exist, it will not
explain the expanding local universe.
All we would need for our universe to be expanding would be for the
bubble to be growing. However, it may be that our universe is not
expanding at all but, because of the red shift, merely appears to be.
Consider: If, as a result of inhomogeneity in the cheese, matter is
being accelerated toward the wall of the bubble and is absorbed by the
bubble once it hits the wall, we will cease being able to detect it and
will see that boundary as the "horizon" of our universe. Also, if the
matter is sufficiently accelerated and goes luminal at some point we
will cease being able to detect the matter and view, instead, what

we would percieve as the background radiation. On the other hand, if it
didn't go luminal, but merely smacked into the wall radiation would also
be emitted. In either case, radiation would be coming at us from
everywhere in the sky, as it does.
---
---A second objection to your theory is the obvious one of asking why such
bubbles should occur in the first place, and, if they should form, what
prevents the surrounding medium from collapsing back onto them.
Whether our universe was formed by by a big bang, a bubble, or something
else, it's obviously here and was formed with no regard for your
objections. The question of 'why' is perhaps best left to philosophy.
I have no problem with the bubble being in a state of expansion,
contraction, or stasis, any of the three being possible.
---
---gravitational effects on a surrounded sphere may be zero, the self
attraction of the surrounding medium is not zero and the enclosure will tend
to close, quite rapidly. Why then does our universe continue to exist?
If it _is_ in a state of contraction, it just hasn't closed in on us
yet?
---
---Third, if the surrounding medium exists, why is all we see from the edge of
the universe the cosmic microwave background radiation?
See above
---
---The argument that
the radiation from the surrounding medium is redshifted to microwave
frequencies by the gravitational effects of the surreounding medium does not
hold water for the reasons explained above. If the surrounding superdense
medium exists, we should be able to see the radiation from the inner surface
of the bubble.
See above
---
---In fact the whole universe should be so awash with radiation
at all frequencies that life as we know it would be impossible.
Regardless of the spectral distribution of radiation in the universe,
life, as we know it, has evolved by adapting itself to the conditions
which exist _on our planet_, with its inherent filters surrounding us.
---
---might have noticed it, myself!
Not necessarily. Fish that live in the deep ocean have no inkling that
they're swimming around with a pressure of 10,000PSI all around them.
---
---Fourth; for us to observe a equal universal expansion in all directions, we
would have to be close tothe exact centre of th surrounded sphere. This
souds just a little coincidental to be likely, anthropic principle aside..
I'm not ruling out equal universal expansion, but at the moment I'm
postulating acceleration within a fixed volume.
---
---I'm sorry, John, but I cannot subscribe to your theory. There are too many
holes in it, and the pun is entirely intended!
Apology accepted!^)
---
---However, there is every probability that our universe, viewed as a whole, is
the contents of a all encompassing black hole.
Not _every_ probability, _some_ probability.
---
---Actually, this seems to be a suitable subject for a whole new thread, but
probably not in the present news group. Do you know of a suitable group
where we could start such a thread and continue it without interfering with
the main purpose of the host group? A few opinions apart from ours on this
subject would add flavour tothe stew of contention.
There are undoubtedly groups where this material is on-topic, but I
don't mind continuing it here (this is currently cross-posted to four

---
---It appears that dark matter may exist, although the case is as yet unproven.
However, darkmatter, unfortunately, does exist.
I have to ask you, John, how much time and effort have you wasted dealing
with darkmatter and his ilk and whether or not you would prefer to post to a
group where you could speak your mind openly without having to put up with
darkmatter's purile excresences and the similar eminations of those like
him.
I'm surprised that at the end of an otherwise rancor-free discussion you
find it necessary to sign off by adding fuel to a fire you say you'd
