“Hic sunt leones,” remarks Stefano Liberati, one of the authors of the paper and director of IFPU. The phrase refers to the hypothetical singularity predicted at the center of standard black holes — ...

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 ...

Three physicists have proposed a modification to Einstein’s general relativity that, if confirmed, could eliminate the singularity at the origin of the universe. By adding higher-curvature terms to ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. A team of scientists has developed a recipe for black holes that eliminates one of the most troubling aspects of physics: the ...

A LONG TIME ago, in a galaxy far, far away—somewhere in the general direction of the constellation of Leo—two black holes crashed together and merged. About 1.3bn years later, on January 14th 2025, a ...

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, ...

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 ...
