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 team of scientists has developed a recipe for black holes that eliminates one of the most troubling aspects of physics: the central singularity, the point at which all our theories, laws and models ...

Everything that falls into a black hole falls in at the same time. Perhaps in the distant past, some unfortunate alien astronaut was sent past the event horizon to explore what lies beyond. From our ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American The singularities at the centers of ...

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 ...

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 ...

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, ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...
