Gravity Is Being Special Again
Our most fundamental theories tell us that there's just no limit at all on how much information you can store in any region of spacetime. And also just the very simple fact that it's a finite number, has a finite number of bits of information which you would not have guessed from any non gravitational quantum field theory. Gravity is again being special. We don't know how to do it but compared to accessing all these would be tiny regions in which we can store information, it's actually much easier to make a black hole.
