Isi artikelFor more than a decade, physicists running an experiment called DAMA, about 1,400 metres under Gran Sasso, a mountain near L'Aquila in central Italy, have been fighting a lonely battle. They claim to have detected dark matter--an invisible substance thought to be five times as abundant as the familiar electrons, protons and neutrons of "ordinary" matter--but until a few months ago almost everyone else who runs similar experiments did not believe them. Now, those opponents are being won over. The latest converts are the members of the CRESST collaboration, also based at the Gran Sasso laboratory (the tunnel leading to which is pictured above). They said on September 6th that they, too, had data suggesting the existence of weakly interacting massive particles (WIMPs), the objects of which dark matter is hypothesised to be composed. That followed an announcement in May that an American experiment called CoGeNT had also seen evidence of WIMPs.
