An expanding universe, say theorists, would contain vacuum energy at ever greater densities.

理论家说，一个膨胀的宇宙将包含密度越来越大的真空能量。

What would make this possible is that the properties of vacuum energy are dependent on the size of the universe as a whole.

使这成为可能的是真空能量的特性取决于整个宇宙的大小。

In a daring theoretical leap, Dr Pearson and his colleagues suggest that the pockets of vacuum energy present in black holes could be responsible.

皮尔逊博士和他的同事提出了一个大胆的理论飞跃，认为黑洞中存在的真空能量袋可能是造成这种现象的原因。

Previous work has shown that, in general relativity, the compression of matter past a certain point can lead to the formation of a zone containing vacuum energy, the background energy of empty space.

先前的工作表明， 在广义相对论中，物质压缩超过某一点会导致形成一个包含真空能量的区域，即真空的背景能量。

One of the simplest and most popular ideas is that there's an everywhere-permeating vacuum energy with negative pressure which we've never detected in any way other than by measuring the expansion of the universe...so we call it dark energy.

最简单且最受欢迎的想法之一是到处都是负压渗透的真空能量，除了通过测量宇宙的膨胀，我们从未以任何方式探测到过。所以我们称之为暗能量。
