Summary

Story summary

MIT physicist Josu Aurrekoetxea reported a possible dark-matter imprint in GW190728.
The team built a model to separate dark-matter signatures from vacuum waveforms.
They applied the model to 28 clear LIGO-Virgo-KAGRA events from the first three runs.
Only GW190728 showed a dark-matter preference, while the other 27 matched vacuum.
The authors noted low significance, urged independent checks, and published the work on May 12, 2026.
