Novikov self-consistency principle

The Novikov self-consistency principle is a concept in the realm of theoretical physics, particularly in the context of time travel and general relativity. Proposed by the Russian physicist Igor Novikov in the 1980s, the principle addresses the paradoxes that arise when one considers scenarios involving time travel. At its core, the Novikov self-consistency principle asserts that any events that occur as a result of time travel must be self-consistent.
