基于RW度规或新度规的无奇点宇宙学模型及其对宇宙演化的解释
Cosmological Models Without Singularity Based on RW Metric or A New Metric and their Explanation for Evolution of the Universe
摘要：
提出了一个新的猜想，即存在两种对称的物质，称为s物质和v物质，它们的引力质量彼此相反，尽管两者的质量都是正的。因此，有两种对称性破缺，称为V-破缺和S-破缺。在S破缺中，s粒子得到它们的质量并形成s星系等，而v-费米子和v-规范玻色子仍然是无质量的，并形成v-SU（5）单态。v-SU（5）色单态之间除了引力外没有相互作用，因此它们在空间中松散地分布，无法被观测到，并导致空间加速膨胀。当温度升高到临界温度时，由于空间收缩，所有粒子的质量为零，因此s粒子和v粒子相互转化，引力质量密度变为负值。因此，空间停止收缩和膨胀必须发生。再加热后，空间首先减速膨胀，然后加速膨胀到现在。没有时空奇点。宇宙中存在着临界温度、最高温度和最小尺度。得到了描述距离红移的公式。一个巨大的空洞并不是空的，相当于一个巨大的凹透镜。在巨大的空洞中氢的密度一定比传统理论预测的要小得多。距离足够远的两个星系之间的引力将小于传统理论所预言的引力。一个质量和密度足够大的黑洞会转变成白洞。解释了原始核合成和CMB。宇宙可能是由无限的宇宙岛组成的。讨论了能量守恒问题。
英文摘要：
A new conjecture is proposed that there are two sorts of matter called s-matter and v-matter which are symmetric and whose gravitational masses are opposite to each other, although both masses are positive. Therefore, there are two sorts of symmetry breaking called V-breaking and S-breaking. In the S-breaking, s-particles get their masses and form s-galaxies etc., while v-fermions and v-gauge bosons are still massless and form v-SU(5) singlets. There is no interaction among the v-SU(5) color-single states except gravitation so that they distribute loosely in space, cannot be observed and cause space to expand with an acceleration. When temperature increases to the critical temperature because space contracts, masses of all particles are zero so that s-particles and v-particles transform from one to another and the gravitational mass density becomes negative. Consequently, space stop to contract and inflation must occur. After reheating, space first expands with a deceleration and then expands with an acceleration up to now. There is no space-time singularity. There are the critical temperature, the highest temperature and the least scale in the universe. A formula describing distance-redshift is obtained. A huge void is not empty, and is equivalent to a huge concave lens. The densities of hydrogen in the huge voids must be much less than that predicted by the conventional theory. The gravitation between two galaxies with distance long enough will be less than that predicted by the conventional theory. A black hole with its mass and density big enough will transform into a white hole. Primordial nucleosynthesis and CMB are explained. It is possible that the universe is composed of infinite cosmic islands. The problem of energy conservation is discussed.
