Rice University physicists used a grain-of-sand-sized magnet levitated above a superconductor cooled to near absolute zero to search for ultraheavy dark matter. Results presented in September 2026 found no signal but probed particles approximately 10 mill
📍 The outcome
Rice University physicists presented September 2026 results showing that the grain‑of‑sand‑sized levitated magnet detected no ultraheavy dark‑matter signal while probing particles of approximately 10 mill. The experiment was described as opening a new frontier and prompting further development of ultra‑sensitive floating‑magnet sensors.
