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 work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...

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 ...

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe ...

Quantum entanglement—once dismissed by Albert Einstein as “spooky action at a distance”—has long captured the public imagination and puzzled even seasoned scientists. But for today’s quantum ...
