Einstein believed that black holes didn't really exist. But they do: that much we know. We don't know much else about them.

Intriguingly, ultralight dark matter might be able to turn into photons (light) — and it's through this process that the ...

Primordial black holes could inhabit the modern-day cosmos, making them responsible for the phenomenon of dark matter, according to new research.

An eavesdropper hiding inside a black hole could still obtain information about quantum objects on its outside, a finding that reveals how effectively black holes destroy the quantum states near their ...

If this scenario plays out, “the world as we know it would collapse like a house of cards,” says one theoretical physicist.

The black hole information paradox has puzzled physicists for decades. New research shows how quantum connections in spacetime itself may resolve the paradox, and in the process leave behind a ...

A new paper proposed by the researchers has said that dark matter may have contributed to the formation of giant black holes ...

In 2022, experts from the University of Amsterdam simulated a black hole event horizon to test Stephen Hawking's 1974 radiation theory.

String theory, an attempt to merge gravity with quantum physics, says yes. A new study suggests that within black holes lie tangled pathways of strings called supermazes, which hold that ...

"Now, our recipe for regular black holes goes precisely in this direction, but instead of using a complete theory of quantum gravity, we use something called an 'effective theory.' This is a ...

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these ...
