Nuclear reactor experiment rules out one dark matter hope
It was an anomaly detected in the storm of a nuclear reactor so puzzling that physicists hoped it would shine a light on dark matter, one of the universe's greatest mysteries.

While many studies have hinted at the existence of dark matter, a material that does not absorb, reflect or emit light, this elusive substance has not been directly observed so far. Over the past few decades, many teams worldwide ...
At the center of spiral galaxies—those near to us but also those billions of light-years away—there is a vast spherical region made up of dark matter particles. This region has two defining characteristics: a density ...
