Impossibly powerful 'ghost particle' that slammed into Earth may have come from an exploding black hole — and it could upend both particle physics and cosmology

An impossibly powerful "ghost particle" that recently slammed into Earth may have come from a rare type of exploding black hole, researchers claim.

If true, the extraordinary event may prove a theory that could upend our understanding of both particle physics and dark matter, the team argues. However, this is just one theory, and there is no direct evidence to confirm that this is indeed what happened.
