I thought that the holographic idea had been ruled out, But this article shows that it could be ruled in again. https://www.sciencedaily.com/releases/2017/03/170321110344.htm And this new research has implications for some fundamental problems in physics. So far, the study of gravity has largely defied efforts to bring it under the umbrella of quantum mechanics, but theorists continue to look for connections. "Our classical theory of gravity relies on knowing exactly the shape or geometry of space-time," Del Maestro says, but quantum mechanics requires uncertainty about this shape. A piece of the bridge between these may be formed by this new study's contribution to the "holographic principle": the exotic contention that the entire 3-D universe might be understood as two-dimensional information -- whether a gargantuan black hole or microscopic puddle of superfluid helium.
