Extraphysical Thermodynamics Problem

The Extraphysical Thermodynamics Problem examines whether thermodynamic principles—especially entropy, irreversibility, and equilibrium—apply beyond conventional physical reality. If higher dimensions, probability universes, or extraphysical realms exist, it is unclear whether entropy increases there, resets, transfers between universes, or behaves in non-classical ways. This problem challenges the assumption that the arrow of time and heat death are universal features of all realities. It raises questions about whether extraphysical domains allow entropy leakage, entropy inversion, or entropy-free states, potentially enabling phenomena that appear impossible under standard thermodynamics within a single universe.

Extraphysical Thermodynamics Problem — Example

Suppose one universe reaches heat death while another nearby universe (with similar physical laws) appears to reset into a low-entropy state. If entropy can be transferred or diluted across universes, then the second law of thermodynamics may only apply locally. This raises the question of whether entropy “leaks” into extraphysical realms or if some universes act as entropy sinks for others.
