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 ...

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 ...

Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...

Black holes remain at the forefront of contemporary physics, challenging our understanding of gravity and the fabric of spacetime. Central to this intrigue is the cosmic censorship conjecture, which ...

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 ...

Chinese astronomers have spotted a hidden supermassive black hole in the background of a peculiar gravitational wave event from a black hole merger, hinting that all three singularities were locked in ...

Astronomers examining data from the James Webb Space Telescope say they’ve spotted what might be the oldest black hole in the universe, born less than a second after the Big Bang. Their findings, ...
