Black Hole

Scientists believe they have cracked one of the most pressing mysteries surrounding black holes that has boggled experts for decades. Black holes are among the most extreme and strange objects we know of, birthed from the collapse of gigantic stars. They are objects with such an intense gravitational pull that…

Credit: CC0 Public Domain Researchers may have solved Professor Stephen Hawking's famous black hole paradox—a mystery that has puzzled scientists for almost half a century. According to two new studies, something called "quantum hair" is the answer to the problem. In the first paper, published in the journal Physical Review…

In the 1970s, Stephen Hawking found that an isolated black hole would emit radiation but only when considered quantum mechanics. This is known as black hole evaporation because the black hole shrinks. However, this led to the black hole information paradox. If the black hole evaporates entirely, physical information would…

Space is home to mysterious giants—black holes that have grown larger and faster than scientists expect. The formation of these behemoths may share a common root with another cosmic mystery, dark matter, according to a recent study. Astrophysicists know that violent deaths of stars can form black holes typically up…

Black holes form when massive stars run out of fuel and implode Scientists say they have solved one of the biggest paradoxes in science first identified by Prof Stephen Hawking. He highlighted that black holes behave in a way that puts two fundamental theories at odds with each other. Black…

With 90 detections now under our belt, gravitational waves are solving riddles about the evolution of galaxies and missing black holes – and they could soon give us a glimpse of dark matter Physics 16 March 2022 By Stuart Clark Ollie Hirst IN A darkened room in Sweden, beneath a…

The formation of ultrarare supermassive black holes, with masses over one billion solar masses, in the first billion years of the Universe is an open question in astrophysics. Brookhaven National Laboratory theoretical physicists Hooman Davoudiasl, Peter Denton, and Julia Gehrlein have developed a model to explain the formation of these…

An audit of NASA's infosec preparedness against insider threats has warned it faces "serious jeopardy to operations" due to lack of protection for unclassified information. A Monday report found that NASA has done well, as required, in its efforts to defend and prevent insider threats to classified information – stuff…

Their surprise discovery has revealed clues about how the universe’s biggest black holes could have formed. Astronomers found evidence for hidden black holes in these dwarf galaxies, among others.

Nothing can escape a black hole, not even light. In simple words, they are the regions of space with an extremely strong gravitational field. But we can see the effects black holes have on the space around them.  Black holes remain one of the most mysterious objects in-universe. Understanding them…
