Black holes are regions in space where gravity is so strong that nothing, even light, can escape. Einstein's theory of ...

The most energetic "ghost particle" neutrino ever detected may have been blasted at Earth by blazars, black hole engines that ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And anything that ...

Thanks to a theory put forward by Albert Einstein over 100 years ago and a happy coincidence, astronomers have discovered radiation being pumped out from the core of a quasar — within which a ...

In 1974 Stephen Hawking famously claimed that black holes should emit particles as well as absorb them. This so-called "Hawking radiation" has not yet been observed, but now a research group from ...

There were lots of ideas about what we might see, but the Universe is full of surprises. One of the first surprises was the ...

Astronomers suspect that the flare is a a burst of radiation that occurs when a black hole consumes a hapless star, ripping it apart and swallowing it. Astronomers are continuing to monitor the black ...

The 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.

Black holes live forever, at least according to general relativity. Once material crosses a black hole's event horizon, it is trapped forever, until the last day of cosmic time. But we know that isn't ...

Tiny black holes created in the aftermath of violent cosmic collisions could offer unprecedented insight into the quantum structure of space and time, a new theoretical study proposes. What's more, ...

I WAS recently asked for my definition of “hard science fiction” and I burbled something along the lines of “it has to have a lot of science in it, and also spaceships”. I’m not sure the spaceships ...
