Physicists Report Levitation Experiment That May Signal a Breakthrough in the Search for Mysterious Dark Matter

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 million times heavier than those examined in previous levitated-particle experiments.

A magnetically levitated sensor extended the ultraheavy dark-matter search by seven orders of magnitude in mass reach, setting limits without a confirmed detection.
