A UK, Canadian and Italian study has provided what researchers believe is the first observational evidence that our universe could be a vast and complex hologram.
Theoretical physicists and astrophysicists, investigating irregularities in the cosmic microwave background (the 'afterglow' of the Big Bang), have found there is substantial evidence supporting a holographic explanation of the universe -- in fact, as much as there is for the traditional explanation of these irregularities using the theory of cosmic inflation.

A holographic universe, an idea first suggested in the 1990s, is one where all the information, which makes up our 3D 'reality' (plus time) is contained in a 2D surface on its boundaries.Professor Kostas Skenderis of Mathematical Sciences at the University of Southampton explains: "Imagine that everything you see, feel and hear in three dimensions (and your perception of time) in fact emanates from a flat two-dimensional field. The idea is similar to that of ordinary holograms where a three-dimensional image is encoded in a two-dimensional surface, such as in the hologram on a credit card. However, this time, the entire universe is encoded!"
So there is a reason you feel like you're living in the Matrix.

Black holes are generally assumed to have singularities at their center, thus there is nothing to fill the volume. The two entities then become the non-dimensional singularity and the event horizon. Since surface area and volume are both functions of the radius you could equate the entropy to the volume of the black hole, but physicists tend to use the simplest relations when possible so surface area wins.
As for entropy and black holes, well that is Nobel Prize stuff right there so good luck!
