Black Hole of Los Alamos Seller of surplus nuclear research materials (2011)

The Black Hole was a Los Alamos surplus store that resold decommissioned gear from the national lab, from vintage oscilloscopes to A-bomb detonator cables, functioning as both a hardware bazaar and an informal museum of the nuclear age. Its closure in 2017 marks the loss of an unusual channel where lab-grade equipment and Cold War artifacts flowed back to tinkerers, researchers, and collectors.

• The shop resold surplus equipment from Los Alamos National Laboratory, spanning 1950s instruments to nuclear-era components.
• It doubled as a de facto museum where every exhibit carried a price tag.
• The business ceased operations as of March 2017.
