Researchers hope an underground experiment called DUNE, or the Deep Underground Neutrino Experiment, will reveal the elusive particle.
Seventy-thousand tons of liquid argon, trillions of particles moving at nearly the speed of light, an abandoned mine-turned-lab a mile underground, over 1,000 scientists and more than a billion dollars — all to catch what optimistic calculations suggest will be a single particle each day.
It’s a staggering amount of effort, but a search for some of the most elusive particles in the universe may just be worth it.
