Astronomers have spotted a supermassive black hole ripping apart and devouring a star in colliding galaxies. It is only the ...

Besides particles like sterile neutrinos, axions and weakly interacting massive particles (WIMPs), a leading candidate for ...

When people think of black holes, they imagine something dramatic: a star exploding in space, collapsing in on itself, and ...

That is, unless they collect around black holes. Superradiance can operate on dark photons just as well as it does on normal photons. When dark photons collect around black holes, they can get ...

The origin of dark energy has been perplexing scientists for decades. When astronomers discovered that the universe is expanding at an accelerating rate, they theorized that some force must be ...

Fifty years ago, physicist Stephen Hawking offered one idea for what dark matter might be: a population of black holes, which might have formed very soon after the Big Bang. Such "primordial ...

Early in the search, renowned British physicist Stephen Hawking postulated that dark matter could be hiding in black holes — the main subject of his work — formed during the big bang.

A rendering of a black hole’s extreme gravitational field redirecting and distorting light. Astrophysicists speculate that these cosmic behemoths could be tied to another enigmatic entity: dark energy ...
