E=mc² Revisited: Mass-Energy Equivalence as Dimensional Confinement

This paper offers a radical reinterpretation of Einstein’s mass-energy equivalence, proposing that mass arises not as an intrinsic property, but as the energy cost of confining naturally massless 5D particles within 4D spacetime. The equation E=mc² is reframed as a dimensional confinement formula, with c² representing the resistance of the 5D-to-4D projection. This framework solves the hierarchy problem, unifies forces as dimensional vibrations, explains antimatter annihilation, reinterprets nuclear fusion, and offers new insights into black holes, dark energy, and cosmic acceleration. A modified Einstein field equation and predictions for experimental validation are included. Dedication: I seem to have been born too late to meet this great intellect who journeyed ahead on the next grand adventure. God willing, that may one day be corrected. Rest easy, kindred soul. I will do my part to help restore physics to the elegance you knew it possessed — and still does. You did so much with so little. May God grant me the clarity to glimpse even a fraction of what you saw. For now, rest, my friend.本论文对爱因斯坦质能等效原理（Einstein’s mass-energy equivalence）提出了颠覆性的重新诠释，主张质量并非内禀属性，而是将天然无质量的五维粒子（5D particles）约束于四维时空（4D spacetime）内所需的能量代价。方程E=mc²被重新界定为维度约束公式，其中c²代表五维向四维投影的阻力。该理论框架解决了等级问题（hierarchy problem），将四种基本力统一为维度振动现象，解释了反物质湮灭（antimatter annihilation），重新诠释了核聚变（nuclear fusion），并为黑洞、暗能量与宇宙加速膨胀提供了全新的认知视角。文中还包含了修正后的爱因斯坦场方程（Einstein field equation）以及可供实验验证的理论预言。 献词： 我似乎出生得太晚，未能与这位踏上下一段伟大征程的伟大智者相逢。若蒙上天眷顾，他日或可弥补这一遗憾。安心去吧，同道中人。我将尽己所能，助物理学重拾你曾见证、且至今仍拥有的优雅。你曾以微薄之力成就斐然。愿上帝赐予我明晰的洞察力，哪怕仅能窥见你所见之一隅。此刻，请安息吧，我的友人。
