The Tevatron works with protons and antiprotons.

而兆电子伏加速器使用的是质子反质子。

And when an electron and a positron or a proton and antiproton meet, they annihilate.

当一个电子与正电子相遇，或者一个质子与反质子相遇，它们就会抵消。

The European Center for Nuclear Research or CERN uses the Large Hadron Collider, a charged particle accelerator to create and study antiprotons.

欧子究中心（CERN）使用大型强子对机（一种带电粒子加速器）来创究反质子。

Heard about your latest antiproton decay experiment. 20, 000 data runs and no statistically significant results. Very impressive.

听说你最新的反质子衰变实验收集两万数据，却没啥有用的结果？灰常了得。

Unfortunately hadrons, such as protons and antiprotons, are made of smaller bits called quarks.

不幸的是，强子，比如质子反质子，是由名为夸克的更小单元所组成的。

About 10 grams of antiprotons would be enough to deliver a manned spacecraft to Mars in just one month.

大约十克的反质子足以在一个月内将载人飞船送上火星。

We live in a universe that we've done enough looking, because we don't see antimatter, antiprotons anywhere, no matter what we look at, that it's all made out of matter.

我们生活在一个已经充分探索过的宇宙中，因为我们无论观察何处， 都看不到反物质或反质子，这表明宇宙完全由物质构成。 除了在实验室里， 不存在反物质。
