What is dark matter?

I predict it won't be seen because dark matter is simply vacuum with positive zero point pressure.

4. WIMPS: THE UNIVERSE WE CAN’T SEE.
When they were building the Large Hadron Collider it seemed to be all about
finding the Higgs boson.  But there seems to be increasing interest in
using the LHC to to learn something about the 85% of the universe we can't
see. We know it's there because it has gravity, but that's about all it
has. The betting is that it's a particle, and the leading candidate is the
WIMP (weakly interacting massive particle). Gianfranco Bertone in
yesterday's issue of Nature predicts that if there is such a ghostly
particle it will be exposed by LHC in the next few years.
