3.Abstract: Reveals the objective necessity of the sole existence of absolute reference system ∑0 :the effect of clock losing and ruler contracting of any material system in motion with respect to ∑0 is the objective real physical change (the real effect) of this material system in motion, and the physical time and space (the effect of motion) is the unity of opposites between the external form of relativity correctly described by the special theory of relativity and the absolute internal essence with the objective sole existence of ∑0 as the basic marking, points out the errors of the general theory of relativity from the results above and the basic facts of gravitational field, and expounds the gravitational field is a real-time hollow field of motion in essence, and the physical time and space is the unity of opposites between mutually perpendicular images of void and real time and space of 4 dimensions each, understanding the absolute essence of the Lorenz effect or not is the demarcation line between new and old views of time and space, and sets forth the theoretical gist of the time and space views of unity of opposites and the internal unity among the macroscopic level and straight time and space, the bent time and space in gravitational field, and the superimposed time and space in guantum state.
文摘:揭示了绝对参照系∑0唯一存在的客观必然性：任何物系相对于∑0的“运动钟慢、尺缩效应”，都是该运动物系客观上具有蹬真正的物理变化(“真实效应”)；进而揭示了物理时空(运动效应)是具有狭义相对论所正确描述了的相对性外部形式和以∑0客观上唯一存在为基本标志的绝对性内在本质的对立统一．运用上述结果和引力场的基本事实，论证了广义相对论的错误；阐明了引力场本质上是一种实时虚空运动场；揭示了物理时空是互为正交映象的虚实各四维时空的对立统一．阐明了对洛仑兹效应绝对性本质的认识与否，是新旧时空观的分水岭；阐明了对立统一时空观的理论梗要和宏观平直时空、引力场弯曲时空与量子态卷迭时空之间的内在统一性.收藏指正
4.They built diners out of shiny stainless steel, and made brightly colored signs lit by neon gas.
