Figure 1：Magnetic-field-driven superconductor-metal phase transition with multiple quantum critical points in CaFe 1-x Ni x AsF. Exploration of exotic quantum phase transitions has always been a focus ...

Like physics, math has its own set of “fundamental particles”—the prime numbers, which can’t be broken down into smaller ...

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 ...

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 ...

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 ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

A radical new theory by physicist Naman Kumar is challenging the way we think about the birth of the universe. Rather than ...
