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.

在1932年，在宇宙射线中发现了第一批正电子或电子，1955年，伯克利的科学家们成功地获得了质子。

The Tevatron works with protons and antiprotons.

而兆电子伏加速器使用的是质子和质子。

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，或者一个质子与质子相遇，它们就会抵消。

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

听说你最新的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，比如质子和质子，是由名为夸克的更小单元所组成的。

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）来创建和研究质子。

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

大约十克的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， 都看不到物质或质子，这表明宇宙完全由物质构成。 除了在实验室里， 不存在物质。

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

是的，金属铱。这种东西是从陨石中发现的。可以形成质子。
