Time Travel Paradoxes and Entangled Timelines IJQF Weekly Papers • physics.hist-ph updates on arXiv.org / 2d arXiv:2303.07635v4 Announce Type: replace-cross Abstract: For time travel to be consistent with the known laws of physics, the resulting paradoxes must be resolved. It has been suggested that parallel timelines (a.k.a. multiple histories) may provide a resolution. However, so far, a concrete mechanism by which parallel… Read more →
