A broader version of the Extended Causality Hypothesis, applying specifically to thermodynamic laws—proposing that the laws of thermodynamics we know (conservation of energy, increase of entropy, unattainability of absolute zero) apply within our observational domain, but extended thermodynamic principles may operate beyond it. This hypothesis suggests that phenomena that appear to violate thermodynamics (perpetual motion, entropy decrease, energy from nowhere) might be lawful within an extended framework. A system that seems to produce energy might be drawing from thermodynamic dimensions we can't measure; an event that appears to decrease entropy might be exporting it to domains we can't see; what looks like violation might be interaction with extended thermodynamic space. The hypothesis provides a framework for understanding claims of free energy, anomalous cooling, or reverse entropy without dismissing them as impossible—they might be impossible within our thermodynamics but possible within extended thermodynamics.
