## What Jamie wrote

Whew — we now have pretty good proof that we are not living inside of a giant simulation inside some computer.

> If the complexity grew linearly with the number of particles being simulated, then doubling the number of partices would mean doubling the computing power required. If, however, the complexity grows on an exponential scale – where the amount of computing power has to double every time a single particle is added – then the task quickly becomes impossible.
