A recent article at New Scientist suggests that “Our world may be a giant hologram.”

That is, not until Hogan realised that the holographic principle changes everything. If space-time is a grainy hologram, then you can think of the universe as a sphere whose outer surface is papered in Planck length-sized squares, each containing one bit of information. The holographic principle says that the amount of information papering the outside must match the number of bits contained inside the volume of the universe.  Read the full article at New Scientist.

What does this mean for our fundamental perception of life?  Individuality? Pain? Happiness?   Future work in this area should be really interesting.
