Imagine digging deep into the ground, in narrow, dark tunnels that could collapse at any moment. That’s the reality for many people working in illegal mines, known as “rat-hole” mines. These mines are ...

After decades of study, scientists sound genuinely optimistic about the possibility of detecting primordial black holes, which might explain dark matter.

In 1974, Stephen Hawking put forward an intriguing idea: Using the principles of quantum physics, he predicted that even though nothing is supposed to escape a black hole's event horizon ...

The odds, they stress, are not good — perhaps vanishingly small. But if people across the world could look for black holes with little to no specialized equipment: what a wonderful chance to spy ...

As black holes slowly vanish through Hawking radiation, their information may be preserved in subtle space-time ripples, a new theory suggests. Nothing is supposed to escape a black hole's event ...
