TU-GUT-SYSY: Spacetime and Dark Matter Vanish When Electromagnetic Entanglement Entropy Reaches Maximum

This independent theoretical work demonstrates that spacetime, gravity, and the local dark-matter density ρ_DM = 0.300 ± 0.015 GeV/cm³ are not fundamental entities but transient thermodynamic illusions that exist only while the electromagnetic vacuum entanglement entropy can still increase.When the second law of thermodynamics is locally saturated (maximum entanglement entropy), time and space literally cease to exist in that region.The exact value 0.300 GeV/cm³ emerges analytically, with no free parameters, from the observed galactic magnetic coherence length (∼1 kpc) and the standard electromagnetic vacuum entropy density.Three immediate, decisive experimental tests are proposed:Measurable weight reduction (Δm/m ∼ 10⁻⁴–10⁻³) of any object inside a closed perfect superconductor (Meissner phase). Absence of extra gravitational lensing in cosmic voids (lowest B-field regions). Complete disappearance of the constant phase in MAGIS-100/AION-km/ZAIGA when shielded with superconductors. Confirmation of any single prediction would prove that the universe, at the deepest level, is pure timeless electromagnetic coherence.Independent research – Simon Soliman, Rome (Italy) – 2 December 2025 Contact: [e-mail]: dark matter, emergent spacetime, entanglement entropy, second law, superconductor anomaly, galactic magnetic fields, timeless physics本独立理论研究证实，时空、引力以及局域暗物质密度$ ho_ ext{DM} = 0.300 pm 0.015 ext{GeV/cm}^3$并非基本实体，而是仅在电磁真空纠缠熵仍可增加时存在的瞬态热力学幻象。 当热力学第二定律在局域达到饱和（即纠缠熵达到最大值）时，该区域内的时空将彻底不复存在。 $0.300 ext{GeV/cm}^3$这一精确数值可通过解析方式求得，无任何自由参数，推导依据为观测到的星系磁场相干长度（约1千秒差距）与标准电磁真空熵密度。 本文提出三项可立即开展的决定性实验验证方案： 1. 封闭完美超导体（迈斯纳态）内部的任意物体均可观测到质量减轻现象（$Delta m/m sim 10^{-4}–10^{-3}$）； 2. 宇宙空洞（磁场最弱区域）中不会出现额外的引力透镜效应； 3. 当使用超导体进行屏蔽时，MAGIS-100、AION-km及ZAIGA实验中的恒定相位将完全消失。 任意一项预测的验证均可证实，宇宙在最本质层面上是纯粹的无时间电磁相干态。 独立研究——西蒙·索利曼，意大利罗马——2025年12月2日 联系方式：[e-mail] 关键词：暗物质、涌现时空（emergent spacetime）、纠缠熵、热力学第二定律、超导体反常现象、星系磁场、无时间物理学
