Spin‐Spacetime Censorship

Quantum entanglement and relativistic causality are key concepts in theoretical works seeking to unify quantum mechanics gravity. In this article, we show that the interplay between relativity theory has intriguing consequences for spacetime surrounding elementary particles with spin. Classical gravity theories predict a spin-generated magnetic dipole field causes (slight) bending around particles, breaking its spherical symmetry. Motivated by apparent break of symmetry, propose very general gedanken experiment does not rely on any specific classical or gravity, analyze context information. We spin-related deviation from symmetry would violate causality. To avoid violation causality, measurable particle's rest frame must remain spherically symmetric, potentially as back-action act measurement. This way, our proves there be censorship mechanism preventing possibility spacetime-based spin detection, which sheds new light interface emphasize proposed is independent allowing quantized purpose used testing present future candidate
