It all has to do with the way we calculate entropy inside a given system.

For some context: The notion that a black hole is actually a holographic facade goes back to the 1990s, when Stanford University physicist Leonard Susskind first hypothesized that the universe as a whole just needed two dimensions for the laws of physics to operate correctly. The world appears 3D to us, but it’s not.
