The Tevatron works with protons and antiprotons.

而兆电子伏加速器使用是质子和反质子。

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

是，强子，比如质子和反质子，是由名为夸克更小单元所组成。

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，它们就会消。

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

听说你最新反质子衰变实验收集两万数据，却没啥有用结果？灰常了得。

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

大约十克反质子足以在一个月人飞船送上火星。

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

欧洲核子研究中心（CERN）使用大型强子对撞机（一种带电粒子加速器）来创建和研究反质子。

Yeah, iridium. It's found in meteorites. It forms anti-protons.

是，金属铱。这种东西是从陨石中发现。可以形成反质子。

As early as 1932, the first positrons or anti electrons were discovered in cosmic rays and in 1955, scientists from Berkeley managed to obtain anti protons.

早在1932年，在宇宙射线中发现了第一批正电子或反电子，1955年，伯克利科学家们成功地获得了反质子。

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宇宙中，因为我们无论观察何处， 都看到反物质或反质子，这表明宇宙完全由物质构成。 除了在实验室里， 存在反物质。
