Is a black hole really just sound and fury, signifying nothing? If the new theory suggesting that these gravitational irregularities are actually just holograms proves correct than, yes, that would be a fair description. But the authors of the new paper in Physical Review Letters putting the argument forth have a long way to go to prove their case. 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.
