Universe-shaking collision of black hole and neutron star could upend our understanding of monster cosmic mergersThe catastrophic collision of a black hole and a neutron star sent ripples across the universe. New analysis of those ripples could upend a major theory about how these extreme pairs form.

The earliest black holes in the universe may still be with us, surprising study claimsThe earliest black holes in the universe may not have disappeared from Hawking radiation after all, new research hints. Instead, they fed on the energy of the ancient cosmos to grow supermassive.

Impossibly powerful 'ghost particle' that hit Earth may have come from an exploding black holeA supercharged neutrino that smashed into our planet in 2023 may have been spit out by an exploding primordial black hole with a "dark charge." If true, this theory could lead to a definitive catalog of all subatomic particles and unveil the elusive identity of dark matter.
