Wave-Crash Spacetime

Time travel is energetically prohibitive under known physics. Forward jumps require a minimum of 1.53 × 10²² J for a 70 kg traveler to skip 100 Earth-years while aging 1 year (black-hole hover at TON 618, γ=100). Backward jumps scale with entropy unmixing: E_rev(t) ≥ T₀ [ n₀ (4/3)π (D t)^(3/2) k + 1.5 t ], rendering long jumps impossible. We propose spontaneous spacetime wave crashes: local curvature peaks reach the Planck density threshold, forming a micro-singularity that evaporates via Hawking radiation. The affected causal patch is then reconstructed holographically at t−Δt via a local, ultra-rapid inflationary process. This paradox-free reset explains the Mandela effect—alternate timelines are physically realized, then erased and overwritten. The key feature is the persistence of non-local quantum memory states which decouple from the reconstructed classical reality, serving as "fossils" of the deleted timeline. Predictions include memory-anomaly clusters after global events and testable clock desyncs coincident with gravitational-wave transients.
