"... a strange new class of these objects that behave completely differently – 'closet eaters' that emit virtually no detectable radiation as they wolf down nearby matter."

"It's a picture of a "subterranean void" on Mars, taken by the HiRISE ultra-high-resolution camera on the Mars Reconnaissance Orbiter. The resolution on that photo is 25 centimeters per pixel; the void shown is about 100 meters across."

"If so, it would help resolve a quantum conundrum known as the black hole information paradox, but critics say it would also raise new problems, such as how the wormholes would form in the first place."

"Ironically, black holes aren’t too hard to find. They’re bright. Here’s a bunch of ‘em..." Space is not just big, it's quite pretty too - and great fun to think about.

"...since that famous thought-experiment wormholes have been described and designed in a multitude of physics papers - but do they exist?" The science behind the fiction. Link via Centauri Dreams.

"Astronomers have looked under the hoods of quasars, the brightest objects in the universe, and found some of the best evidence yet for the black holes that are thought to power them."

Magnetic fields are the key to the paradox that black holes provide nearly a quarter of the radiation in the universe.
