论文摘要
在本文中，我们旨在研究与宇宙背景场有关的对称的特殊相对论（SSR）众所周知的相对论动力学，该动力学与宇宙背景领域有关，该动态扮演着与宇宙膨胀的宇宙温度相关的可变真空能量密度的作用，并在其早期膨胀的时间内与宇宙膨胀相关，并在其较远的将来的时间内加速了。在这种情况下，我们表明，光速和不变的最小速度对扩展宇宙的背景温度具有明确的依赖性。尽管在早期的宇宙中找到了非常高的温度的光速，并且在非常较低的温度非常旧的宇宙中，分别大得多，并且比当前价值小得多，但我们的方法并不违反特殊相对论的假设（SR），该假设声称光速在运动学的观点中是不变的。此外，结果表明，早期宇宙中光速的高价值在通货膨胀期开始之前分别大幅下降和分别增加。因此，我们得出的结论是，不同的光速理论（VSL）应作为对热宇宙的地平线问题的可能解决方案的质疑。
In this paper we aim to investigate a deformed relativistic dynamics well-known as Symmetrical Special Relativity (SSR) related to a cosmic background field that plays the role of a variable vacuum energy density associated to the temperature of the expanding universe with a cosmic inflation in its early time and an accelerated expansion for its very far future time. In this scenario, we show that the speed of light and an invariant minimum speed present an explicit dependence on the background temperature of the expanding universe. Although finding the speed of light in the early universe with very high temperature and also in the very old one with very low temperature, being respectively much larger and much smaller than its current value, our approach does not violate the postulate of Special Relativity (SR), which claims the speed of light is invariant in a kinematics point of view. Moreover, it is shown that the high value of the speed of light in the early universe was drastically decreased and increased respectively before the beginning of the inflationary period. So we are led to conclude that the theory of Varying Speed of Light (VSL) should be questioned as a possible solution of the horizon problem for the hot universe.
