Scientists have no reported evidence of the actual conditions in Hell, perhaps because no one has ever returned to tell the tale. Hell has been imagined as a supremely uncomfortable place, hot and hostile to bodily forms of human life, similar to a black hole. Thanks to a vast astronomical survey of the entire sky, ...
Recent observations of a black hole devouring a wandering star may help scientists understand more complex black hole-feeding behaviors. Multiple NASA telescopes recently observed a massive black hole tearing apart an unlucky star that wandered too close. Located about 250 million light-years from Earth in the center of another galaxy, it was the fifth-closest example ...
If, as astronomers believe, the death of large stars leaves behind black holes, there should be hundreds of millions of them scattered throughout the Milky Way galaxy. The problem is that an isolated black hole is invisible. Now, a team led by the University of California, Berkeley, astronomers has for the first time discovered what ...
Astronomers have unveiled the first image of the supermassive black hole at the center of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the center of most galaxies. The ...
When two neutron stars spiral into one another and merge to form a black hole — an event recorded in 2017 by gravitational wave detectors and telescopes worldwide — does it immediately become a black hole? Or does it take a while to spin down before gravitationally collapsing past the event horizon into a black ...
A new study has discovered that the powerful jets of wind that blast out of a black hole only occur after it has built up a hot outer layer of plasma, known as its corona. Researchers observed the behavior of a black hole in our galaxy and developed a cosmic echocardiogram graph showing its “heartbeat.” ...
What if everything around us was just… a hologram? Does this describe a black hole? The thing is, it could be — and a University of Michigan physicist is using quantum computing and machine learning to better understand the idea, called holographic duality. Holographic duality is a mathematical conjecture that connects theories of particles and ...
For the first time, scientists believe they have detected a black hole merger of two black holes with eccentric orbits. According to a paper published in Nature Astronomy by researchers from Rochester Institute of Technology’s Center for Computational Relativity and Gravitation and the University of Florida, this can help explain how some of the black hole mergers detected by LIGO ...
Black hole feeding patterns offer insight into their size, researchers report. A new study revealed that the flickering in the brightness observed in actively feeding supermassive black holes is related to their mass. Supermassive black holes are millions to billions of times more massive than the sun and usually reside at the center of massive ...
The black holes at the centers of galaxies are the most mysterious objects in the Universe, not only because of the huge quantities of material within them, millions of times the mass of the Sun, but because of the incredibly dense concentration of matter in a volume no bigger than that of our Solar System. ...
