Abstract: Now or never for WIMPs? Particle physicists have proposed many different solutions to the dark matter problem: dark matter constitutes 85% of all the matter in the Universe, but we still don't know what it actually is. Of the competing candidates, WIMPs (weakly interacting massive particles) are attracting particular attention because they arise naturally from new theories that seek to extend the standard model of particle physics. In a review in this issue of Nature, Gianfranco Bertone explains why he thinks the moment of truth has arrived for WIMPs. If the Large Hadron Collider at CERN, Europe's particle-physics lab near Geneva, Switzerland, and the latest astroparticle experiments fail to observe WIMPs in the next decade, he reckons, the new era of physics will be on hold for 20 years or more. By that time, a new generation of particle colliders might have arrived.
