Hour documentary about the nature of reality

From BBC One, an episode of Horizon exploring that good ol' mindfucking question "What is reality?"

Clues have been pieced together from deep within the atom, from the event horizon of black holes, and from the far reaches of the cosmos. It may be that that we are part of a cosmic hologram, projected from the edge of the universe. Or that we exist in an infinity of parallel worlds. Your reality may never look quite the same again.

  1. Aren't we kind of bound by the fact that our descriptions of reality will always be an abstraction? By the time you get to trying to convey the nuances of new physics to a lay audience, its a very abstract description of reality indeed.

  2. Being able to understand and use those abstractions is the mark of the scientist. Other groups have other narratives.

  3. As much as I deride the misapplication of specific scientific or mathematical principles for the sake of driving home pop philosophical points (I'm looking at you What the Bleep Do We Know), I heard somewhere that one of the implications of Gödel's incompleteness theorems is that it is impossible to prove the internal consistency of a system without relying on other information that lies outside that system. Sadly, that will probably doom cosmology forever.
