Generating universes within universes with a single seed
SMRTR summary
Computer-generated "random" numbers aren't truly random but come from deterministic mathematical algorithms that create massive predetermined lists of pseudorandom values, all starting from a single seed number. Using simple equations like linear congruential generators, a seed creates an entire universe of billions of predetermined outcomes for everything from statistical simulations to Minecraft worlds, meaning every "random" event is already decided once you set the seed.
