Sabine | Why Carlo Rovelli Thinks You Might Be Hallucinating

The Boltzmann brain hypothesis states that, between the Big Bang occurring and a fully-formed brain suddenly popping into existence in space, the brain spontaneously appearing is more probable.

In a recent paper, a group of physicists have compared the second law of thermodynamics and the Boltzmann brain hypothesis – after analyzing both, they concluded that both are equally legitimate theories of physics.


Let’s take a look at what this means and if they might be right.
