Scientists are pinning hopes on elaborate detectors to track the elusive material that holds galaxies together
Deep underground, scientists are closing in on one of the most elusive targets of modern science: dark matter. In subterranean laboratories in the US and Italy, they have set up huge vats of liquid xenon and lined them with highly sensitive detectors in the hope of spotting subatomic collisions that will reveal the presence of this elusive material.
However, researchers acknowledge that the current generation of detectors are reaching the limit of their effectiveness and warn that if they fail to detect dark matter with these types of machines, they could be forced to completely reappraise their understanding of the cosmos.
