Black holes are some of the most violent and destructive objects in the universe. And as terrifying as it sounds, thousands of these mysterious voids could be whizzing through your home at this ...

Asteroid-mass primordial black holes might whiz through the inner solar system just once a decade. Luckily, scientists have decades of data on satellites’ trajectories.

Black holes are almost unimaginably dense.If Earth was (hypothetically) crushed into a black hole, it would be under an inch across. Today, many black holes form following the collapse of massive ...

With the rate of primordial black hole passages calculated and considering the asteroid-range mass of these dark matter candidates, the team then reasoned that these tiny black holes would race ...

Earth is perfectly safe from a menacing asteroid known as 2024 YR4 that is big enough to level a city, but the moon? Not so much.

These black holes could be as wide as a single atom, but weigh as much as a huge asteroid. "Ordinarily, black holes form from the collapse of dying stars," Kaiser told Newsweek.

Primordial black holes, on the other hand, might have formed shortly after the Big Bang, when areas of dense space also collapsed inwards, before stars even existed—hence the primordial part.

A potential lunar collision with asteroid 2024 YR4 could eject high-speed debris toward Earth, endangering our satellite ...

To find black holes we usually have to look thousands of light-years away. ... That’s roughly the mass of 324 Bamberga, the 16th-largest asteroid in the main belt.
