The Statistical Improbability of Your Existence

It is mathematically more likely for a single brain to randomly pop into existence out of the void than for our entire massive universe to have evolved naturally.

This unsettling concept suggests that any memory you have could be an illusion created by a lone brain flickering into life for just a split second. Physicists use this idea to challenge their own theories about how the cosmos began. If a theory predicts that lone brains should be more common than universes, they know something in their math is deeply wrong. It forces us to question if our reality is actually as stable as it appears.
