==suggestions==
This article needs some attention from an expert. It focuses only on detection, and doesn't do an adequate job of discussing theoretical or observational reasons for expecting that WIMPs might exist. It talks about how to make patterns of mass distribution of galaxies fit observations by inserting cold dark matter in a simulation, but doesn't discuss, e.g., cosmic microwave background measurements, which, IIRC, rule out baryons as the main form of dark matter. The following sentence doesn't make sense: "Although predicted scattering rates for WIMPs from nuclei are significant for large detector target masses,prediction that halo WIMPs may, as they pass through the Sun, interact with solar protons and helium nuclei." There is no real discussion of their possible particle-theoretical properties. Are they assumed to be fermions? If so, why? Are they their own antiparticles? Are they expected to come in families? The article refers to supersymmetry. Do WIMPS exist generically in all supersymmetric models? What kind of bosons would their supersymmetic partners be?--[[Special:Contributions/76.93.42.50|76.93.42.50]] ([[User talk:76.93.42.50|talk]]) 03:45, 20 February 2008 (UTC)
==Possible WIMP discovery==
They're no longer a "hypothetical" class of particles. In December 2009, researchers in the Soudan mine announced that they may have observed WIMPs. [[User:Stonemason89|Stonemason89]] ([[User talk:Stonemason89|talk]]) 16:40, 18 December 2009 (UTC)
