Zhang told the Reuters news agency that most planetary bodies are made of groups of rocks joined under the influence of gravity.

张告诉路透社，大多数行星体是由在引力作用下结合在一起的岩石群组成的。

Newton, and others, should have realized that a static universe would soon start to contract under the influence of gravity.

牛顿和其他人应该已经意识到，静态宇宙很快就会在引力的影响下开始收缩。

Most of the time this difference doesn't matter, because if you weigh two things in the same place on the same scale, they're both under the same influence of gravity.

大部分时间这种差异一点也不重要，因为当你在同一个地点用同一个秤量不同东西的重量它们其实受到一样多的影响。

Unlike dark matter which clumps under the influence of gravity, dark energy appears to have a repulsive effect that causes the universe to expand at an accelerating rate.

与在重力影响下聚集的暗物质不同，暗能量似乎具有排斥效应，导致宇宙加速膨胀。
