Paul Steinhardt, a theoretical physicist at Princeton University, says theorized forms of dark energy could be time-dependent in a different way.

普林斯顿大学理论物理学家保罗·斯坦哈特表示，暗能量的理论形式可能以不同的方式依赖于时间。

In some cosmological models that Steinhardt is investigating, the contraction might turn back into expansion and produce a kind of cyclical universe.

在斯坦哈特正在研究的一些宇宙学模型中，收缩可能会转回膨胀并产生一种循环宇宙。

The findings provide the earliest evidence of actual cooking, as opposed to just throwing meat and bones into a fire, says Irit Zohar at the Steinhardt Museum of Natural History in Tel Aviv, Israel.

以色列特拉维夫斯坦哈特自然历史博物馆的伊里特·佐哈尔（音译）说，这些发现提供了实际烹饪的最早证据，而不仅仅是把肉和骨头扔进火里。
