Speculations on What Could Show Physics Beyond the Standard Model (opens in new tab)

Post-spacetime physics refers to the idea that our familiar 4D spacetime is not fundamental but emerges from deeper structures—whether geometric (fiber bundles, higher-dimensional manifolds), quantum (entanglement, information), or vacuum effects. Eric Weinstein’s Geometric Unity (GU) proposes a 14-dimensional geometric framework (involving a metric bundle over 4D spacetime) from which the Standard Model forces, gravity, and ... Read more
