Physicists Report Strongest Evidence Yet for Dark Matter Particle
Underground detector records signals consistent with long-theorized weakly interacting particles.
Scientists operating a deep underground detector have reported signals that may represent the first direct detection of dark matter particles.
## The Detection
The detector recorded 23 events consistent with weakly interacting massive particles (WIMPs), the leading dark matter candidate.
## Statistical Significance
The results exceed the threshold for statistical significance, though scientists emphasize that independent verification is essential.
## What is Dark Matter
Dark matter accounts for 85% of the universe's mass but has never been directly detected. Understanding it is one of physics' greatest challenges.
## Next Steps
Multiple detector experiments worldwide are attempting to replicate the findings, which could fundamentally change our understanding of the universe.
