A laser-driven tidal wave could test a question that has long plagued physics: is the information inside a black hole lost forever or somehow preserved through the mysterious machinations of quantum mechanics?
Study finds that if two black holes collide, they would release as much energy as 100 million supernova explosion.
A black hole 11 million light-years away has gone dormant, a decade after being spotted consuming cosmic debris.
An unparalleled image from NASA’s Chandra X-ray Observatory is giving an international team of astronomers the best look yet at the growth of black holes over billions of years beginning soon after the Big Bang.
Every few thousand years, an unlucky star wanders too close to the black hole at the center of the Milky Way. The black hole’s powerful gravity rips the star apart, sending a long streamer of gas whipping outward.
Researchers at Heriot-Watt University in Edinburgh have built their own “black hole” in the laboratory.
Spinning black holes are capable to implement complex quantum information processes with qubits encoded in the light emitted by the accretion disk.
White holes are basically black holes in reverse: They eject all the matter sucked into a black hole. We’ve never observed one, and most astrophysicists suspect they don’t exist – all because they’re not the exact opposite of black holes.
Astronomers using the super-sharp radio vision of the National Science Foundation’s Very Long Baseline Array (VLBA) have found the shredded remains of a galaxy that passed through a larger galaxy, leaving only the smaller galaxy’s nearly-naked supermassive black hole to emerge and speed away at more than 2,000 miles per second.
After the first direct detection of gravitational waves that was announced last February by the LIGO Scientific Collaboration and made news all over the world, Luciano Rezzolla (Goethe University Frankfurt, Germany) and Cecilia Chirenti (Federal University of ABC in Santo André, Brazil) set out to test whether the observed signal could have been a gravastar or not. The results were recently resented in a paper published on Physical Review D.
