Size of the universe

we see now. But the universe has gone on to expand those 13 billion
years. The universe is much bigger than our telescopes see by 13
billion years(of expansion.)

This is true. However, you still reach the causal horizon farther
out. What's beyond it? Should we petition NASA to send a mission
there to beam back some imagery of "the other side"?

Our Universe Has a Topology Scale of at least 24 GPC
Our universe has a topology scale of at least 24 Gpc, or
about 75 billion light years, according to a new analysis
of data from the Wilkinson Microwave Anisotropy
Probe (WMAP).
What does this mean? Well, because of conceivable
hall-of-mirrors effects of spacetime, the universe might
be finite in size but give us mortals the illusion that it is
infinite. For example, the cosmos might be tiled with
some repeating shape, around which light rays might
wrap themselves over and over ("wrap" in the sense
that, as in video games, something might disappear off
the left side of the screen and reappear on the right
side).
A new study by scientists from Princeton, Montana
State, and Case Western looks for signs of such
"wrapped " light in the form of pairs of circles, in
opposite directions in the sky, with similar patterns in
the temperature of the cosmic microwave background.
If the universe were finite and actually smaller than the
distance to the "surface of last scattering" (a distance
that essentially constitutes the edge of the "visible
universe," and the place in deep space whence comes
the cosmic microwaves), then multiple imaging should
show up in the microwave background.
But no such correspondences appeared in the analysis.
The researchers are able to turn the lack of recurring
patterns into the form of a lower limit on the scale of
cosmic topology, equal to 24 billion parsecs, a factor of
10 larger than previous observational bounds. (Cornish,

No horizon. Hypersphere expansion.

Yes, Mitch :-)

"The scale and the substructure, i.e. 30 degree-radius rings and
voids in the distribution of the excursion sets around the
antipodes, reveal features of mirroring which cannot be
explained either via global (integrated Sachs-Wolf effect)
or local inhomogeneities of matter. The anomaly is also
not close to the apex of the CMB dipole arisen due to the
motion of the Earth i.e. of the detector. This mirroring
effect can be the first empirical signature of a Universe
with compact topology, potentially of either curvature."
and
"The mirrored structures cannot be explained simply via inte-
grated Sachs-Wolf effect or via nearby matter anomalies10, i.e.
either by means of global or local inhomogeneities. Mirrored fea-
tures however, would be expected in a Universe with a compact
topology; for examples of hyperbolic and other spaces see e.g.
ref.[11,12]. If we, indeed, deal with the first empirical signature
of a compact space, this result and this method of analysis can
open a new path towards overcoming the curvature/topology de-
generacy and revealing the genuine shape of the Universe."
