【物理】暗能量。
-
What dark energy is, though, is a mystery.
然而暗能量是什么,仍然是个谜。
-
Dark energy, however, is an unknown unknown.
但是,暗能量却是一个未知的未知。
-
Dark energy is a more daunting problem still.
暗能量依旧是一个更加令人却步的问题。

What is dark matter, dark energy, gravity?—stem
什么是暗物质,暗能量,重力?

Dark energy is possibly even more baffling than dark matter.
暗能量大概要比暗物质更让人无头绪。
暗能量是某种作用于时空结构本身的能量,并且是种均匀的负压力,会导致时空结构膨胀。暗能量这个名词由迈克·透纳引进。 它和暗物质都不会吸收、反射或者辐射光,人类无法使用已有技术进行直接观测。暗能量假说是对宇宙加速膨胀的观测结果的解释中最为流行的一种。
-
The leading idea for dark energy is that it is a cosmological constant.
有关暗能量的主导观点认为它是一个宇宙常量。

The remaining 68% of the energy density of the universe is made up of dark energy, which is even more mysterious than dark matter.
剩余68%的宇宙能量密度来自于暗能量,这种物质比暗物质更加神秘。

So, as the universe expands as it is doing right now, there will be more and more dark energy.
因此,随着宇宙不断膨胀,正如此时此刻,暗能量也会随之不断增长。

This dark energy doesn't behave like any other substance we know at all and acts more like anti-gravity force.
这种暗能量的性质与我们所熟知的其他物质完全不同它更像是反重力。

So, tell me about your scalar dark energy experiment. Not 'til you tell me about your latest paper on quantum loop theory.
跟我说说你的标量场暗能量实验。你先跟我说说你最新的论文圈量子理论。

I'm thinking about how one could use the fact that a rapidly rotating mirror turns virtual photons into real ones as a method of observing dark energy.
我在思考,高速自转的镜子可以将虚光子转成真光子这一现象如何运用在获取暗能量上。

Because of this property of the cosmological constant, the future universe will be more and more dominated by dark energy, becoming colder and colder and expanding faster and faster.
因此,由于宇宙常量所具有的性质,未来的宇宙中更多充斥的将是暗能量,宇宙将会变得越来越冷其膨胀速度也会越来越快。
