Is the universe truly expanding, or collapsing?

Brian We have a theory by Andre linde his ideas developed a "new
inflationary universe". Lots of his ideas fit in with Guth's but
Linde theory answered more questions. Linde's theory told us inflation
was due to the universe being chaotic,and at the very beginning need not
have been very hot. You see Brian reality is no one could explain what
caused it to be so hot.Linde theory took away the assumption of a hot
pre-inflationary universe. If he said it in this group he would be
"flamed to death" Linde used "fields"(random fields in space to create
the chaotic space conditions) Fields associated with all Quantum
particles,that fill all of space even before the BB Gravity field
associated with mass. Fields associated with forces that hold nuclei
together ,and the list goes on. With Linde's great thinking I can fit
in my concave,convex theory for gravity attraction and universe
repulsion. when I'm ask now what is curving space ,I now can answer
"fields" It all fits Bert

Thanks.

It's making some sense, though why does it apply at the universal level
and not at the local level? Like the fabric of space between Earth and
the Sun changing by a measurable amount? Is it just too small to be
measurable at this time? (I'm guessing yes)

On local scales, gravity fields are strong enough to overcome
the universal expansion. That's why we have galaxy clusters and
superclusters. These clusters will continue to contract locally
under gravity, but each cluster will become more and more
isolated as universal expansion moves them further apart.

An example of this is that although we are some 20 million
parsecs away form the Virgo Cluster, we are moving towards it
at astonishing speed. Our Local Group of galaxies and the
Virgo Cluster are all part of a larger supercluster that is
still contracting.

The upshot of this is that although we always talk about redshifts
when we look at distant galixies, when we look at the Virgo
Cluster, we see blushifts!

Hello to you

Hi Vos,
I'm glad to see you use the term "center of the universe" as I
believe also, that there is a definite center. However, your scenario
of the galaxies collapsing into the center defies observational
evidence. While the galaxies lined up from near to far away from the
center linerally could exhibit isotropic red shifts (except for one
thing that I'll get to next), as they neared the center, galaxies
sideways to them would be getting closer together and would exhibit
BLUE shifts! Also, Hubble deep field observations show galaxies
receding from us at up to 12 times light speed. Superluminal galaxies
further away from the center in the collapse than ourselves would be
unobservable by us as we would be outrunning radiation from them.
So the opposite scenario exists and Ia supernovae rise time
observational evidence proves conclusively that the universe is
expanding. Further, since there has to be a definite center, the milky
way galaxy and local group have to be at said center. Otherwise, as
stated earlier, we would not be able to observe superluminal galaxies
in all directions.

You can't copyright a theory (or any idea), only the document that
expresses it.

The universe is expanding at an accelerating rate.
This is evidence of one universe with a begining and
an infinite future.

The universe isn't infinite.
There are no infinite quantities or sizes.
Only the future is infinite.

Time never ends; not even in black holes.
