Summary:
- Researchers at the University of Toronto are conducting an experiment called SuperCDMS (Cryogenic Dark Matter Search) to detect dark matter particles deep underground in the Sudbury Neutrino Observatory.
- The experiment involves cooling detectors to extremely low temperatures, just above absolute zero, to increase their sensitivity and ability to detect the faint interactions of dark matter particles.
- This milestone achievement of reaching such low temperatures is an important step in the ongoing search for dark matter, which is believed to make up a significant portion of the universe's mass but has not yet been directly observed.
