Question

急！急！急！哪位英语高手帮我翻译一下，谢谢！

1、Before, I know nothing about dark energy. Now, I know that dark energy is a hypothetical form of energy that permeates space and exerts a negative pressure, which would have gravitational effects to account for the differences between the theoretical and observational results of gravitational effects on visible matter.
2、科学家通过对超新星的测量发现重力加速了宇宙膨胀的速度。
3、The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession.

Answer 1

1.之前，我不知道暗能量。现在，我知道暗能量是一种假想的能源形式贯穿空间和施加负压，将重力的影响考虑之间的差异的理论和观测结果的引力影响可见物质.
2.Scientists through the supernova survey found the speed of gravity accelerates the expansion of the universe.
3.接收频率高（相对于发射频率）的方法，它是相同的在瞬间通过，它是在较低的衰退。

追问

第一句好像不怎么通顺呢？

追答

主要我们不是学这个专业的，你如果是这个专业你把上面语句再重新整理一下。
