AI Summary

Scientists report that a detected gamma‑ray signal could represent the first direct evidence of weakly interacting massive particles (WIMPs), a leading dark‑matter candidate. The signal was observed in data from a space‑based gamma‑ray telescope, and its energy spectrum matches predictions for WIMP annihilation. If confirmed, the finding would provide the first tangible detection of the substance that makes up about 85% of the universe’s mass.
