Wheeler-Feynman Absorber Theory
A theory of electrodynamics where radiation is explained by the interaction between emitters and absorbers, involving advanced (backward in time) and retarded (forward in time) waves.

Causality-Consistent Teleportation
Teleportation is possible via non-linear quantum mechanics, but only if it does not involve backward time travel that violates causality. The universe allows translocation as long as the timeline remains self-consistent.
The Universe as a 'Cheating' Consistency Enforcer
The universe actively eliminates impossible timelines (like the Bilking paradox) rather than preventing the attempt, effectively 'cheating' to ensure only consistent histories exist.
