Physicists Daniel Jampolski and Luciano Rezzolla have published a peer-reviewed paper in Physical Review D describing, for ...

Thanks to the Event Horion Telescope, we now know black holes exist, but a new study published recently in Physical Review D ...

A ring in space, at least on paper, can do something a black hole cannot. It can connect distant regions without forcing ...

Can we do away with the troublesome singularity at the heart of black holes? A new paper in JCAP reimagines these extreme objects in light of current knowledge. “Hic sunt leones,” remarks Stefano ...

At the center of each classical black hole is a paradox: a singularity, where gravity is infinite and the laws of physics break down. But a new theoretical breakthrough says such cosmic dead ends aren ...

A LONG TIME ago, in a galaxy far, far away—somewhere in the general direction of the constellation of Leo—two black holes ...

What lurks at the center of a black hole? Studying the space-time ripples from black hole collisions could reveal an answer. When you purchase through links on our site, we may earn an affiliate ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

After a three-year hiatus, scientists in the US have just turned on detectors capable of measuring gravitational waves—tiny ripples in space itself that travel through the universe. Unlike light waves ...

A cartoon of a black hole and a naked singularity. Either of them can be the end product of a gravita tional collapse of matter, depending on initial and other conditions. For a black hole, nothing, ...
