The Probability Maxim: All possibilities are played out somewhere in Probability.
The Probability Paradox: Probability travel links universes into continua that invalidate the Probability Maxim. First noted by the Wyrm philosopher Ryzan in 720 BC.
Artonic Quantum Theory: Artonic energy can only be expended in discrete units or quanta. This limits the amount to which Probability can be fractured, thus restricting which universes can be reached from any given universe and creating multiple interlaced continua – thus preserving the Probability Maxim. Disproven when the energy value of the Artonic Quanta was shown to be beneath the minimum necessary to fracture Probability.
Meta-Probability Theory: Championed by Zurvár physicist Àeksùl this theory proposed a second dimension of Probability, creating continua inaccessible to standard Artonic Probability travel. Fell into disfavour after the death of Àeksùl in his tragic laboratory disaster.
Harmonic Probability Theory: Probability can only be fractured in discrete units, restricting what universes are accessible and creating multiple interlaced continua – thus preserving the Probability Maxim. The currently accepted solution to the Probability Paradox.
