This is something some of my brothers might be more likely to post about. I found an article, via Jeff Rowland's Overcompensating, that describes in quite understandable terms the possibility that the universe is a hologram. Apparently--and I've done just enough extra research that I'm fairly confident that this isn't a joke--a facility in Germany designed to study gravity has stumbled upon noise predicted by the now head of Fermilab.
Now, they seem to mean hologram in the science sense, not the science-fiction sense. A hologram is n-dimensional information stored in n-1 space; most commonly this is a 3-d image on a plane. It's been demonstrated that the surface of a black hole's event horizon emits, in a spherical 2-d space, the information about it's 3-d interior. The story goes that our universe might actually be information encoded on the universe's event horizon. As a result, the minimal quantum of information would be significantly larger than previously thought... like 10^-16 instead of 10^-35. The significantly lower resolution of the universe is what some think (though they won't go so far as "theorize") the German research station is picking up.
The metaphysical implications are not broached.
And this awful hipster music they're playing at Verite is awful.
