What experimental tests and quantum simulations of closed timelike curves exist as of 2025-2026? Cover weak measurement tomography, P-CTC quantum processor experiments, input-output indefiniteness, an
While no direct observation of closed timelike curves (CTCs) exists as of 2026, experimental quantum simulations have begun probing CTC-like causal structures in the lab. These experiments use postselection, weak measurements, and indefinite causal order to simulate time-travel…
What do tachyons, Gödel's rotating universe, and ER=EPR tell us about backwards time travel? Cover tachyon signaling paradoxes, Gödel CTCs, and entanglement-wormhole duality as of 2025-2026.
Three distinct paths connect backwards time travel to modern physics: tachyons (hypothetical FTL particles), Gödel's rotating universe (the first GR solution with CTCs), and ER=EPR (the conjecture that entanglement and wormholes are dual). As of 2025–2026, all three have seen…
Quantum Perspective on Backwards Time Travel: CTCs, Deutschian Models, and Qiskit Simulation Hypotheses
Closed timelike curves (CTCs) were first discovered by van Stockum (1937) and Gödel (1949) as exact solutions to Einstein's field equations, proving that general relativity mathematically permits backwards time travel [src-1, clm-4]. However, these solutions raise paradoxes such…
What does current physics say about backwards time traveling? What are the theoretical mechanisms (wormholes, CTCs, warp drives), paradox resolution principles, and the experimental/quantum status as
Backwards time traveling is not science fiction in the mathematical sense — general relativity admits exact solutions containing closed timelike curves (CTCs) that loop back into the past. Van Stockum (1937) and Gödel (1949) were first to show this formally, and today CTCs are a…
What does current physics say about time travel? Cover closed timelike curves, wormholes, warp drives, paradoxes, chronology protection, and the Novikov self-consistency principle as of 2026.
Time travel remains one of the most fascinating concepts in physics, with general relativity (GR) providing mathematically consistent frameworks that permit backward time travel through closed timelike curves (CTCs) [src-692a6566d690, src-3b90e8c18935] [claim-3c5bd4e9407e]…
