Could tiny black holes be hiding in planets or even everyday objects?
When you think of black holes, you probably imagine massive stars collapsing under their own gravity.
But scientists have long theorized the existence of primordial...

Early black holes fed 40x faster than should be possible
The theory goes that black holes accrete material, often from nearby stars.
However the theory also suggests there is a limit to how big a...
How did supermassive black holes get so big, so early
Supermassive Black Holes (SMBHs) can have billions of solar masses, and observational evidence suggests that all large galaxies have one at their centres.
However, the...
A star disappeared in Andromeda, replaced by a black hole
Massive stars about eight times more massive than the Sun explode as supernovae at the end of their lives.
The explosions, which leave behind a...
