Despite containing civilizations from multiple realities, SINK operates under a unified set of physical laws. Upon entering SINK, displaced matter gradually stabilizes and conforms to local physics. This process prevents contradictory realities from destroying one another.
Gravity, chemistry, energy transfer, and biological processes remain consistent throughout known space unless disrupted by active Void anomalies. Advanced technologies from different civilizations often remain functional because they adapt to these universal constants.
Localized anomalies may temporarily alter gravity, time perception, electromagnetic behavior, dimensional stability, or causality. Such regions are dangerous, heavily studied, and often quarantined. These effects are considered environmental hazards rather than normal conditions.
Reality itself constantly resists instability. Large-scale dimensional events require enormous energy and are exceptionally rare.
