Noun . English Wikipedia has an article on: Boltzmann brain. Wikipedia . WebIn modern physics, Boltzmann brains can be formed either by quantum fluctuation, or by a thermal fluctuation generally involving nucleation. Via quantum fluctuation By one calculation, a Boltzmann brain would appear as a quantum fluctuation in the vacuum after a time interval of 101050{\displaystyle 10^{10^{50}}}years.

WebHow do you know you're a person who has lived your life, rather than a just-formed brain full of artificial memories, momentarily hallucinating a reality that doesn't actually exist? That may sound absurd, but it's kept several generations of top cosmologists up at night. They call it: the Boltzmann brain paradox. Fabio Pacucci explores this mind-numbing thought … The Boltzmann brain thought experiment suggests that it might be more likely for a single brain to spontaneously form in a void (complete with a memory of having existed in our universe) rather than for the entire universe to come about in the manner cosmologists think it actually did. Physicists use the … See more In 1896, the mathematician Ernst Zermelo advanced a theory that the second law of thermodynamics was absolute rather than statistical. Zermelo bolstered his theory by pointing out that the Poincaré recurrence theorem shows … See more According to one hypothesis, in the universe's eventual state of ergodic "heat death", given enough time, every possible structure (including … See more In Boltzmann brain scenarios, the ratio of Boltzmann brains to "normal observers" is astronomically large.
