Scientists at CERN first produced antimatter in 1996 in an experiment that created antihydrogen.

欧洲核子研究组织的科学家于1996年在一次制造反氢的实验中首次制造出了反物质。

Last year ALPHA used a magnetic trap to hold on to antihydrogen atoms for a record 16 minutes.

去年ALPHA成功地使用磁阱，创纪录地令反氢原子存活长达16分钟之久。

He said that the research ruled out that gravity pushes antihydrogen away from the center of the Earth.

他说，这项研究排除了重力将反氢推离地球中心的可能性。

Later, thanks to advanced technologies, physicists were able to obtain not just antiparticles, but whole anti-atoms, anti helium, and antihydrogen.

后来，由于先进的技术，物理学家不仅能得到反粒子，而且能得到整个反原子、反氦和反氢。

During the experiment, researchers said the antihydrogen particles were moving around at a speed of about 100 meters a second.

在实验中，研究人员表示，反氢粒子的移动速度约为每秒100米。

Measuring the light spectrum of antihydrogen is a key part of solving that mystery.

测量反氢的光谱是解开这个谜团的关键部分。

And a great way to test that idea is by comparing the light coming from hydrogen and antihydrogen.

测试这个想法的一个好方法是比较来自氢和反氢的光。

But what they found was that the antihydrogen emitted the exact same spectrum of light as hydrogen.

但他们发现，反氢分子发出的光谱与氢分子完全相同。

So, in 2011, antihydrogen lasted as long as 1,000 seconds and in 2014, eighty anti hydrogen atoms were created for the purpose of a detailed study.

因此，在2011年，反氢原子持续了一千秒，而在2014年，为了一项详细的研究，八十个反氢原子被创造出来。

Working out of the CERN lab in Switzerland, these researchers figured out how to capture about 14 antihydrogen atoms within a 15-minute cycle.

在瑞士 CERN 实验室工作的这些研究人员想出了如何在 15 分钟的周期内捕获大约 14 个反氢原子。
