In 2025, a team analyzing data from the XENONnT experiment found a statistical excess at low energies that matches the spectrum predicted by a "Sternberg extension" of the Lorentz group. While not yet confirmed, this has ignited a race to produce the , where dark matter is not a particle but a cohomological obstruction in the symmetry group of the universe.
and its representations, which are fundamental to understanding elementary particle physics and quantum mechanical states. sternberg group theory and physics new
