Simulation Hypothesis

Simulations by floor · 941 simulations

The smallest thing each simulation keeps track of, from quarks up to pure rules. It’s the same ladder as the Sandbox’s matter-floor dial. The lower the floor, the more of reality has to be computed.

floorSubatomic28

Quarks, gluons, nucleons, neutrinos, photons.
