Default Could Fermi telescope detect dark matter within a year?

A group is suggesting that we'll able to see Cold Dark Matter pretty
soon, with the Fermi gamma-ray telescope. They are predicting that
within the first year alone we should see anywhere between 5 to more
than 400. But after 3 months of observations they haven't seen one yet.

The limits of their enthusiasm has been boosted by throwing in a new
theory, called the Sommerfield Enhancement, that suggests that Dark
Matter annihilations can occur more frequently than they thought previously.

This of course assumes that Cold Dark Matter is the right Dark Matter
theory. Then it applies a new equation that makes them even more giddy
about their prospects of finding it, the Sommerfield Enhancement. And of
course the biggest assumption of all is that Dark Matter even exists.

Maybe something can be said about persistence. If your initial
calculations don't show what you want to see, then throw a couple of
more kitchen sink equations in there, and maybe it'll work out then?

"The Fermi Gamma-ray Space Telescope could detect the telltale signs of
dark-matter annihilation in as little as a year, if calculations by UK
and US astrophysicists prove correct. "

There was another group just recently who suggested from their studies
that the gamma rays we're seeing within our galaxy are just coming from
the normal sources such as supernovas and black holes.

"“There is no great mystery. The observed distribution of gamma rays is
in fact quite consistent with the standard picture,” University of
California in San Diego (UCSD) Center for Astrophysics and Space
Sciences researcher Richard Lingenfelter explains. "

Inventing epicycles only postpones the demise of current
paradigm. The need for dark matter will cease when a consensus
is reached that stars do not fly around galactic centers,
planets do not fly around stars and satellites do nor fly around
planets.

So one model among many for dark matter has bit it.

No huge surprise there.

Dark matter would also be in the disc making it heavier than the halo
itself. This is the opposite of what theory requires.

Sorry, didn't quite understand what you mean here. Are you saying that
Cold Dark Matter is no longer viable? Why would you say that, when
these researchers are so sure that they'll detect it soon?
