A new analysis of the “Boltzmann brain” paradox suggests our memories and sense of reality could, in theory, be random ...

In a recent paper, SFI Professor David Wolpert, SFI Fractal Faculty member Carlo Rovelli, and physicist Jordan Scharnhorst examine a longstanding, paradoxical thought experiment in statistical physics ...

Was an incredible drop in entropy responsible for the Big Bang? If that’s the case, this w Was an incredible drop in entropy responsible for the Big Bang? If that’s the case, this would lead us to ...

The Boltzmann brain hypothesis suggests that our memories are nothing more than unlikely fluctuations. According to the theory, the past and the future don’t exist—only the present does. Researchers ...

Explore the Boltzmann Brain paradox and its challenge to entropy-driven explanations of our universe's structure and arrow of time. The Boltzmann Brain paradox is an argument against the idea that the ...

(via TEDEd) 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 ...

To many physicists, “Tsallis entropy” has been a revolution in statistical mechanics. To others, it is merely a useful fitting technique. Jon Cartwright tries to make sense of this world of disorder. ...
