A new x-ray deep field image supports the idea that supermassive black holes formed before galaxies did.
The brightest supernova observed may have been caused by a hungry black hole.
Observations of gravitational waves might allow us to test the quantum properties of black holes.
To make a black hole, do we have to squeeze mass all the way to its limit, or do we just have to get close enough?
It turns out that black holes might have hair after all.
What if black holes don’t exist, but similar objects do? How would we tell the difference?
