虽然目前对暗能量的形态和起源几乎完全未知，不过科学家认为它可能和空间本身所产生的真空起伏有关，或者说与卡西米尔效应有关联。

The form and genesis of dark energy is almost completely unknown, but postulated as related to vacuum fluctuations similar to the Casimir Effect but generated somehow by space itself.

了解真空起伏，是现在科学研究的最前缘课题，它不但有助于我们更了解我们的宇宙，也可以帮助我们找出防止微机械零件粘着在一起的方法。

Understanding vacuum fluctuations is on the forefront of research not only to better understand our universe but also for stopping micro-mechanical machine parts from sticking together.
