What if 85% of the universe is invisibleâand the one experiment claiming to have found it is wrong?
For nearly three decades, Italian physicists have claimed their DAMA/LIBRA experiment detected the elusive particles that make up dark matterâthe mysterious substance holding galaxies together. Yet no one else has ever confirmed it.
Join Brian Keating, UCSD cosmologist and host of The INTO THE IMPOSSIBLE Podcast, as he visits Kaixuan Ni and his teamâscientists building the worldâs most sensitive detectors deep undergroundâto uncover:
- ⢠âď¸ How detectors using liquid xenon can âfingerprintâ single atomic collisions.
- ⢠đĄ Why dark matterâs âheartbeatâ signal divided physicists for 30 years.
- ⢠â˘ď¸ How dark-matter detectors are now being repurposed to detect nuclear weapons and monitor reactors remotely.
- ⢠đ The shocking discovery of solar neutrinos and ultra-rare nuclear decaysâphenomena rarer than the age of the universe itself.
This is the invisible architecture of realityâwhere cosmology meets particle physics, and theory meets obsession.
đ Filmed at UC San Diegoâs Mayer Hall and Harold Urey Hall â home to experiments that may finally prove what 85% of the cosmos is made of.
đ Watch till the end to see how a failed dark-matter search could save the world from nuclear war.
