Dark Matter Hunter Becomes a Hundred Thousand Times Sharper
In a dark room, a hunter waits for a barely audible rustle. Similarly, physicists have spent years listening for signals from dark matter particles — the invisible substance that holds galaxies together but doesn't emit light. The new detector makes this 'hearing' a hundred thousand times sharper.
Inside the device is SF₆ gas (the same stuff that quenches sparks in electrical grids).
