Echoes of Flavio's Ghost Dreaming

"Then, though, there are the BB’s in the universe: Boltzmann Brains. Random fluctuations of the fabric of spacetime itself which, most of the time, are rather insignificant puffs which evaporate immediately. But sometimes they stick around. More rarely, they are complex. Sometimes (very very rarely) they are really quite as complex as us human types. (Actually, “very very rarely” does not quite convey just how rare we are talking now.) And sometimes these vacuum quantum fluctuations attain the status of actual observers in the world. But, the rarest of them all, the BB’s, are able to (however briefly) make actual observations in the universe which are, in fact, “not erroneous” as Don Page put it."

I need coffee in the mornings and a pint in the evenings. But I'm only a guitarist and a music teacher. What, exactly, do theoretical physicists take, in order to help themselves along? I think I may need some....

interesting New Scientist podcast with, amongst other things, an interview with Roger Penrose on the nature of reality.

Pity the Americanese jingle and happy-happy bouncy-bouncy intro. I, at any rate, find it really really irritating.
