本文论述了宇宙太空中存在中微子场。依据中微子存在能量震荡的事实，论证了中微子场形成量子引力场原理。根据太阳中微子失踪事件，推导出中微子场能量密度。进一步推论暗物质不存在，中微子场就是暗能量。以一个简单直观的物理模型，幸运地解答了五个难题。 作者起初只想利用中微子存在能量震荡，光速直线运动，非凡的穿透能力……等特征。以大量中微子流沿径向穿透某球状天体，产生摩擦损耗能量转化为引力子能量的方式，来探索量...

根据“吸纳了测不准原理的新狭义相对论”，针对OPERA中微子速度测量提出一个公式，计算结果显示该实验中μ中微子最高速度为(1-1.6×10-40)c，虽然极近光速但并没有达到光速。既然中微子的速度低于光速，为什么还会出现提前到达现象呢？其原因在于中微子以及所有轻子、夸克并不是点粒子。把提前到达时间δt的测量值代入这个公式可以估算出μ中微子的质量≈5×10-9eV/c2。该公式还指出，δt不随中微子...
