At the Large Hadron Collider, mysterious glitches — UFOs — could turn out to be the 'sound' of dark matter particles weighing grams flying through the Earth. If we hear three such 'thumps' within a couple of seconds, the collider becomes a giant ear for the invisible universe.
🎯 The energy of the sound pulse from such a clump is comparable to the impact of a large meteorite, but only the 27-kilometer LHC ring, turned into a giant seismograph, can hear it.
