Max Tegmark "Our mathematical universe"

OK, at least Mr Tegmark doesn't avoid the question:

What's our universe expanding into?
----------------------------------

Mr Tegmark writes about this question 16 lines. Some of those lines are
wasted with the assurance that no chocks will occur because of space
expansion. At least 4 lines reassuring us, poor souls, that no galaxy
pileup is around the corner.

Well, I am reassured Mr Tagmark. It always amazes me how cosmologists
can hide behind words.

Almost at the end of the 16 lines, almost as an afterthought Mr Tegmark
comes to two "viewpoints". You can see it either as:

Static space: Galaxies are receeding faster and faster from us in a
static space. Well, static space means that there is NO space expansion,
and galaxies are receeding from us at an accelerated rate.

Assuming that red shift equals distance this view point leads to an
horizon. Parts of the universe are receeding faster than light, in 3
dimensions there is no solution.

The other solution is static matter: volume is not constant and new
volume "is created", just like that.

Obviously space is created when nobody is looking. Space hides when
doing this kind of aberrations of course, very shy. Space hides
conveniently in "the space between galaxies".

Ahh ok. How clear.

Imagine I am traveling smoothly between galaxy A and galaxy B. Suddenly,
my space ship incrases its volume. Wow! The machine room got bumped left
of the motor B22, an empty cube of several meters appeared between two
parts of the motor, what made the connexions get loose and the computer
to shut down.

Ahh this dammed space that can't keep it steady and must bump new space
at the worst moments somewhere!

Vulgarisation is not just speaking about the questions with *some*
seriousness. Obviously Mr Tegmark hasn't done any further thoughts into
this particular question than those 16 lines...

At least not in that book. A book that tells "the layman" a story like
you tell it to a child.

Look, laymans like the target audience of this book CAN exist. Do they
actually exist? Maybe.

But in the laws of big numbers, I would bet that in thousands of laymans
about astronomy that buy this book, some of them will be pleased with a
straightforward story of how the universe came into being, nice to know,
you know?

This is all very official, with NASA satellites, etc. Precision cosmology.

I am a layman of course, but I do not agree that the answer is 16 lines
of nothing really. For me this problem is unanswered by the BB people.

The book is in itself interesting because it shows what is really the
stand of BBs.

"Volume appears", just like that!

All this bang disappears if we asssume that (for an unknown reason)
light for distant objects gets red-shifted. No Doppler effect, just
red-shift, what is something different but not related to some "space
expansion".

This conceptual advance will allow astronomers to start looking for the
reason of the red-shift instead of believing that they know what the red
shift is!

A VERY important conceptual step that Mr Tegmark doesn't do.

[Mod. note: tired light theories have well-known problems and are too
speculative to be discussed here -- mjh]
