At the very centre of a black hole, our equations say all the matter is squeezed down into a single point with zero size and infinite density. That description is called a singularity. But scientists are pretty sure this isn't really what's down there — it's more like the equations giving up: 'we don't know, the math broke, please refer to a theory that hasn't been invented yet.' The real centre of a black hole is one of the biggest unknowns in physics. There's something there. We don't know what.
§ Strange but true
- 01Inside a black hole, density goes to infinity, gravity goes to infinity, and physics gives up.
- 02It's almost certainly not a real point — it's a sign that general relativity has broken and quantum gravity should take over.
- 03We don't have a theory of quantum gravity. So we don't know what's actually there.
