论文摘要
最近的数据表明，宇宙可以积极弯曲。结合通货膨胀阶段，这可能导致曲率反弹而不是大爆炸。呈现背景进化，作为控制宇宙进化的参数的函数。还计算了原始张量光谱，并强调了模型的可能的观察足迹。在这种情况下，考虑了几个潜力，并就“自然”发表了一般性评论。
Recent data suggest that the Universe could be positively curved. Combined with an inflationary stage, this might lead to a curvature bounce instead of the Big Bang. The background evolution is presented, as a function of the parameters controlling the cosmic evolution. The primordial tensor spectrum is also calculated and possible observational footprints of the model are underlined. Several potentials are considered and general remarks are made about "naturalness" in this context.
