10 Craziest Facts You Didn't Know About Black Holes

1. They Technically Don't Exist

Depending on how you define existence, you might find that black holes simply don't exist at all.

The old saying "if a tree falls in the forest but no-one is around to hear it, does it make a sound?" applies here a little, in that if all light is absorbed by a black hole, and we can't possibly see what's on the inside, then does the inside really exist?

"Singularity" is just the scientific equivalent of Error 404. Singularities are infinitely dense and infinitely small dots in space. The problem is that "infinity" doesn't exist in the real world, so how can a black hole possibly exist?

But if we're inside a black hole, and if black holes don't exist... Then do we exist?
