If that’s the case, this would lead us to conclude that a great many other things are possible, including the likelihood that you are a Boltzmann Brain.

The lowest entropy state that we’re aware of in our universe was right before the Big Bang. The entirety of our own universe was condensed to a microscopic size. What caused this extreme low entropy? If it was caused by a random fluctuation in particles that implies that a great many other things are possible due to the random fluctuations of particles. One of the strangest of those possibilities is that of the Boltzmann Brain. If the Big Bang was caused by random entropic fluctuations then it is much more likely you are a Boltzmann Brain than that you are a human being.Written and Hosted by Matt O’DowdProduced by Rusty WardGraphics by Kurt RossMade by Kornhaber Brown (www.kornhaberbrown.com)The Great Courses Plus is currently available to watch through a web browser to almost anyone in the world and optimized for the US market.
