Black holes have been understood as infinite singularities for a century. In 1916, months after Einstein published general ...
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 ...
Whenever someone talks about black holes, they almost always talk about the event horizon and the singularity. After all, that's what defines a black hole, right? Well, it depends on what you mean by ...
Einstein spent 10 years wrestling with three fundamental concepts in physics: acceleration, the special theory of relativity, and the gravitational force. This heroic effort culminated in 1915 with ...

A 'naked singularity' problem that vexed Stephen Hawking takes a step closer to reality
By taking general relativity into higher dimensions, a trio of physicists has proven that a mathematical pattern of ripples ...
Falling into a black hole may not be as final as it seems. Apply a quantum theory of gravity to these bizarre objects and the all-crushing singularity at their core disappears. In its place is ...
Certain stealthy spacetime curiosities might be less hidden than thought, potentially exposing themselves to observers in some curved universes. These oddities, known as singularities, are points in ...
