LUX could resolve a decade-long physics debate.

Viewed end on, the arrays of photomulti­plier tubes on the Large Underground Xenon (LUX) experiment look like beds of flowers. The hope is that they will capture sparks of light emitted when particles of dark matter collide with liquid xenon.With 122 detector tubes, LUX is much more sensitive than its closest rival in the competitive field of dark-matter searches — and in just days, physicists the world over will know whether that advantage has yielded definitive results.
