The Digammaverse is verse packed with "number particles". These particles are represented by numbers, each coresponding to a property. The size of each particle is 1 picometer.
The full list of properties: mass, charge, spin, lifetime, speed, acceleratio, magnetic field, weak isospin, weak hypercharge, angle, interaction, color charge, chirality, parity, c parity and isospin.
Each particle has a unique set of numbers, there are no replicas.
This means that there are ~8.488*10298 particles, which makes the Digammaverse ~5.45*1079 light years in diameter.
