What is Boltzmann brain?
The Boltzmann brain thought experiment suggests that it's more likely for a random brain (or even an entire body or galaxy) to spontaneously form with false memories in a vast, fluctuating universe than for the entire universe to develop as [[Cosmologist|cosmologists]] believe. This idea is named after physicist [[Ludwig Boltzmann]]. It is used to challenge our assumptions about [[thermodynamics]] and the universe's evolution. <!-- In a very long time, random fluctuations could lead to the formation of incredibly complex structures, including human brains. This concept gained attention when it seemed that, according to some theories, Boltzmann brains might be more probable than conventional human brains. This raised concerns about the reliability of our memories and understanding of the universe. The Boltzmann brain could form through quantum or thermal fluctuations, and it would typically exist briefly, have a single thought, and then disappear. Some physicists argue that Boltzmann brains may not qualify as true observers. The debate over Boltzmann brains continues in the context of cosmology and our understanding of the universe's fundamental principles. In summary, the Boltzmann brain thought experiment challenges our understanding of the universe's development and questions whether we can trust our memories and observations in a vast, fluctuating cosmos. --> [[Category:Thought]] [[Category:Philosophical concepts]] {{stub}}
