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 ...

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 ...

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 ...

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 ...

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 ...
