Black Hole

Dark matter is the biggest missing piece in our understanding of the cosmos. Despite substantial evidence that dark matter accounts for 85% of all matter in the Universe, there is currently no consensus on its nature. This covers whether dark matter particles may collide with other particles like atoms or…

TAMPA, Fla. — NanoAvionics is preparing to ship a nanosatellite slated to launch this fall to study black holes and neutron stars from low Earth orbit, the Lithuanian manufacturer announced Aug. 7. The company provided its 6U satellite platform for the NinjaSat mission, and integrated it with a payload from…

BBC ordered to end TV licence 'farce' (Image: Getty) Campaigners are accusing the BBC of hounding over-75s who refuse to pay their TV licence. They claim the corporation repeatedly sends “threatening” letters to those rebelling against the scrapping of the freebie three years ago. One elderly refusenik has been slapped…

An artist's impression of a black hole. Could these cosmic monsters devour the entire universe? (Image credit: MARK GARLICK/SCIENCE PHOTO LIBRARY via Getty Images) Black holes are infamous for their immense gravity — they can swallow stars, planets and even other black holes.  But could a black hole consume the…

Akers had already convinced himself that the conversion program should be written in the language of quantum error correction, as Harlow had already worked out for empty space. The semiclassical interior would be the message, and the quantum exterior would be the transmission. And given that the interior seemed to…

One of the universe’s most unusual phenomena is black holes. The chirping sound that two black holes make when they merge can be heard using gravitational-wave detectors; about 70 such chirps have been discovered so far.  The “ocean of voices” in which chirps are thought to predominately occur in two…

This illustration shows, as seen by NASA's IXPE mission, the blazar Markarian 421 blasting out high-energy jet. (Image credit: NASA/Pablo Garcia) A NASA mission has observed a supermassive black hole pointing its highly energetic jet straight toward Earth. Don't panic just yet, though. As fearsome as this cosmic event  is,…

Stellar-mass black holes with masses of roughly 10 suns, for example, reveal their…

Very advanced civilizations could graduate from using regular stars for power and use black holes. Manufacturing of antimatter is hugely energy-inefficient, and antimatter is difficult to contain. The process of generating a Black hole from collapse is naturally efficient. It would require millions of times less energy than a comparable…
