Dark matter defines the headings of galaxies. Where there is more
dark matter, galaxies move there. That region is void of dark matter,
galaxies seem hungry and dark matter itself attracts gravitationally,
but that would not exclude elliptic galaxies being there, and they
are not there. It seems there is no matter there, perhaps matter
has yet to go there, the opposite to inflation, fill up.
Oh and that explains why the region is cold. CMBR does not radiate
the early big bang from there.
In other words, if the big bang happened everywhere, it didn't happen
there.

New analysis puts dark matter back into elliptical galaxies (Forwarded) ... This theory faced a challenge in 2003, when a team of astronomers reported a surprising absence of dark matter in elliptical galaxies. ... But a new analysis published in the September 29 issue of the journal Nature provides an explanation for the earlier observations that fits comfortably with the standard theory and puts the dark matter back into elliptical galaxies.... "A dearth of dark matter in elliptical galaxies is especially puzzling in the context of the standard theory of galaxy formation, which assumes that ellipticals originate from mergers of disk galaxies," added Avishai Dekel, professor of physics at the Hebrew University of Jerusalem and first author of the Nature paper. ... Whereas spiral galaxies are dominated by flattened, rotating disks of stars and gas, elliptical galaxies are round, smooth collections of stars. ... (sci.astro)
