Physicists Daniel Jampolski and Luciano Rezzolla have published a peer-reviewed paper in Physical Review D describing, for the first time within classical general relativity, a step-by-step process by ...

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 ...

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. A new analysis suggests a ring wormhole could, in theory, form closed timelike curves under the right gravitational conditions.

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...

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, ...
