论文摘要
在这封信中，我们认为，从标准物理学和测量的宇宙学参数中推断的宇宙的过去可能是一种非单明的反弹。我们还表明，在此框架中，可以将相当严格的约束放在重新加热的温度和通货膨胀e-folds的数量上，基本上固定$ t_ {rh} \ sim t_ t_ t_ {gut} $和$ n \ sim 70 $。我们得出了一些关于在这种情况下加重潜能形状的结论，并提出了“自然性”问题。最后，我们认为这可以打开“前大弹跳”宇宙中非常具体的窗口。
In this letter, we argue that the past of the Universe, extrapolated from standard physics and measured cosmological parameters, might be a non-singular bounce. We also show that, in this framework, quite stringent constraints can be put on the reheating temperature and number of inflationary e-folds, basically fixing $T_{RH}\sim T_{GUT}$ and $N\sim 70$. We draw some conclusions about the shape of the inflaton potential and raise the "naturalness" issue in this context. Finally, we argue that this could open a very specific window on the "pre big bounce" universe.
