   I think the box explanation is misleading. There isn't literally a box whose surface you measure. The idea is that the state of a higher-dimensional gravitational system can, in some cases, be completely described by a theory in one fewer dimension.

      Is the "in some cases" constraint really necessary? I thought Bousso's whole point in his talk linked elsewhere in this thread is that you can describe a 3D system in terms of 2D information.

      Could you keep going, fully describing systems of higher order in less and less dimensions?
