The Higgs, Boltzmann Brains, and Monkeys Typing Hamlet
If somebody told you that there are angels floating in space, observing our world and forming their impressions of our everyday reality, you would think that this person is nutsâ€”a religious fanatic with an active imagination, and certainly not a scientist. Scientists, as we all know, are rational beings who believe only in what nature reveals to us through experimentation and observation, coupled with theory that is never divorced from the physical measurements they make. The link between the two remains tightly regulated through the strict rules of the scientific method.
So how do you explain the bizarre fact that, for about five years now, some of the worldâ€™s most prominent physicists have been describing a scenarioâ€”which they seem to truly believe may be realâ€”in which, instead of the Biblical angels, space is permeated by disembodied brains?
