big bang cosmology

基本解释

The puzzle of the cosmic age is a long-standing key problem in big bang cosmology.
第一推动力是伴随着宇宙大爆炸的发生一并出现的，它在本质上是一种惯性力。
But even if the circles really do stem from sources in a pre-Big Bang era, cyclic cosmology may not offer the best explanation for them.
但即便这一圆环结构最后被证实果真是大爆炸之前的遗迹，循环宇宙的想法可能也未必是最完美的模型解释。
Between the theories of big-bang cosmology and the theory of stellar structure and theory, there is a gap still rarely understood: how do the galaxies form?
然而在大爆炸宇宙模型和恒星演化理论之间存在一个人们了解甚少的领域：就是由大量恒星组成而又作为宇宙基本单元的星系是如何形成和演化的?。
