I wonder which substance theorists are taking... I will avoid...!
but really this is very preoccupating:
"complex structures will occasionally emerge from the vacuum as quantum fluctuations, at a small but nonzero rate per unit spacetime volume. An intelligent observer, like a human, could be one such structure."
Is this a new alternative to Darwinism...??? a support to creationism ?? How can a physicist can write such non-sense ?
In 1996 Sokal hoaxed sociologists with his famous nonsense text on political implications of quantum gravity. Can one play a similar game with "researchers" on Boltzmann brains, multiverses, string landscapes or similar? I doubt, this is just reality satire that can't be topped.
From my favourite, "applied science" series...
"If you've ever had one too many and tumbled into bed with a vision, only to be greeted in the morning by a sight you'd gnaw off your own arm to escape, take heart".
