Have scientists discovered a dark matter particle? - Al Jazeera
Scientists at the Sanford Underground Research Facility in South Dakota have detected an unexplained particle interaction that may provide evidence of dark matter. While not a confirmed discovery, the finding is considered a significant step in understanding the invisible substance that makes up much of the universe.
Why it matters
This discovery could fundamentally change our understanding of physics and the composition of the universe.
Dark matter is an invisible substance that is said to bind the universe; scientists in South Dakota may have found new signs of it.
