光速随膨胀宇宙温度的变化

Variation of the speed of light with temperature of the expanding universe

Cláudio Nassif Cruz, Antônio Carlos Amaro de Faria

摘要:

从一个扩展的相对论动力学的粒子在宇宙背景场与温度T,我们的目标是获得一个明确的依赖于宇宙的背景温度的光的速度。虽然我们发现早期宇宙的光速比现在大得多,但我们的方法并没有违反狭义相对论的假设。此外,它表明,在早期宇宙中的高值的光速急剧下降之前的暴胀时期的开始。因此,我们得出结论,光速变化理论作为视界问题的一种可能的解决方案应该受到质疑。

英文摘要:

From an extended relativistic dynamics for a particle moving in a cosmic background field with temperature T, we aim to obtain the speed of light with an explicit dependence on the background temperature of the universe. Although finding the speed of light in the early universe much larger than its current value, our approach does not violate the postulate of special relativity. Moreover, it is shown that the high value of the speed of light in the early universe was drastically decreased before the beginning of the inflationary period. So we are led to conclude that the theory of varying speed of light should be questioned as a possible solution of the horizon problem.
