论文摘要
我们从可以用标尺来测量宇宙扩展的E折叠数量的位置。我们发现在通货膨胀，再加热和辐射过程中电子折数数的独立模型界限。在可观察到的通货膨胀开始时，我们还对宇宙的大小进行了下限。最后，我们表明，与相关图的一致性需要存在一种新的能量形式来推动宇宙的当前扩展。
We draw a figure from where it is possible to measure the number of e-folds of expansion of the universe with a ruler. We find model independent bounds for the number of e-folds during inflation, reheating and radiation. We also give a lower bound to the size of the universe at the beginning of observable inflation. Finally, we show that consistency with a relevant diagram requires the existence of a new form of energy to drive the present expansion of the universe.
