摘要
首先根据Einstein场方程中时时分量方程的非独立性,分析了当今天体物理主流学派所提出的"宇亩始终在加速地膨胀"这一论断的错误之所在;进一步又根据系统的内能对时空曲率k的正比关系,分析了天体的内能和压強都是可正可负的,而且正压系統才会自膨胀,负压系统必然自收缩;最后,直接根据Einstein场方程和物态方程分析了天体系统自膨胀和自收缩的无限循环.
The modern astrophysics mainstream school has been said with certainty: "The universe has al ways been acceleration in expansion. " According to the non-independence of the components equation in the Einstein field equation, we have demonstrated this affirm is wrong. Further more, according to the in- ternal of the celestial system is in the direct ratio to the curvature k of the celestial system, for this reason, the internal energy and pressure of the celestial body can be negative or positive, and the negative pressure system will be shrink the positive pressure system will be inflation. Finalty, according to the Einstein field equation and the equation of state of the celestial system, the expansion and contract of the celestial system as in infinite loop have been analyzed.
