How 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 experiment.

Fabio Pacucci: The Boltzmann brain paradox

The Boltzmann brain paradox

An infinitely old universe could randomly create complex entities, but Boltzmann brains are more probable than new universes.

Boltzmann's paradox challenges cosmological models, compelling a reevaluation of universe origins and the likelihood of our reality.

In an eternal universe, random particle assemblies could create transient brains, challenging our reality's authenticity.
