1. Temporal Paradoxes

   Linked via "time traveler"

   Novikov Self-Consistency Principle
   Proposed by physicist Igor Novikov, this principle asserts that the probability of any event occurring that would lead to a paradox is zero. Any actions taken by a time traveler are inherently constrained to be consistent with history. In essence, the laws of physics prevent paradoxes from ever arising. This mechanism is sometimes described as the universe possessing an inherent "causal inertia."
