[FRIAM] the autodidactic universe

[uǝlƃ ☤>$]

Interesting. It sounds a bit like Deutsche's Fabric of Reality. Re whether it had been posted before, there are hints of it in the Wired article I posted back on the 13th, copied below.

Likewise, our aliens come from a region void of dark energy because this void represents a biosphere of computational activity. According to a detailed multidata analysis of the latest measurement of the cosmic microwave background, the Sloan Digital Sky Survey and type Ia supernovae observations, such a region exists. Working with my colleagues at Penn State and CERN, we were able to show that all that data is consistent with a region void of dark energy spanning some two hundred megaparsec. This is a huge region; for comparison, ten kiloparsec is about the radius of a typical spiral galaxy like our own Milky Way, and a parsec itself is already pretty big, at more than three light-years. So we at least have a spot where these aliens could live with their computers. Everywhere outside the aliens’ existence, where there are no computers, the dark energy would exist."
