The first antiparticle was discovered by American physicist Carl Anderson in 1932.

第一个粒是美国物理学家卡尔·安德森在1932年发现的。

After all, when an antiparticle meets a particle, a so-called annihilation occurs.

毕竟，当粒遇到粒时，就会发生所谓的湮灭。

A little later, for every 1 billion particles and antiparticles, there was one extra particle.

不久之后，每十亿个粒粒，就有一个额外的粒。

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，物理学家不仅得到粒，而且得到整个原、氦。

It's just one way of understanding how particles of matter may be similar to and different from their antiparticles.

这仅是从一方面来了解粒物质与它们的物质的异同。

And observing how they are like and unlike their antiparticles could help us understand the very nature of the universe.

可以观测到它们与对应物质的异同，这可以帮助我们了解的本质。

Each time scientists create or destroy a new particle, an antiparticle is born or dies accordingly.

每次科学家创造或摧毁一个新粒，粒就会相应地产生或消亡。

Quantum fluctuations in empty space are constantly creating pairs of particles and antiparticles, only for them to be annihilated an instant later.

空间中的量涨落在无时无刻地创造一对粒粒，只为了在瞬间之后相互湮灭。

Even if we learn how to safely approach antiparticles, we'll need to find a way to travel far back into the past.

即使我们学会了如何安全地接近粒，我们也需要找到一种方法回到遥远的过去。

Scientists use special electromagnetic traps called the quadrupole-loffe configuration which for a short time prevents particles and antiparticles from coming into contact with and annihilating each other.

科学家们使用了一种特殊的电磁陷阱，叫做四极 loffe 配置，它在短时间内防止粒粒相互接触湮灭。

By 2022, scientists plan to construct a portable trap for antiparticles and then drive the antimatter in a truck several hundred meters to another site for further experiments.

到2022年，科学家们计划建造一个便携式粒装置，然后用卡车把物质开到几百米外的另一个地点进行进一步实验。

At the blow of a cosmic whistle, every particle of matter with a particle of antimatter to its immediate right will merge with that antiparticle to —poof! — both annihilate.

在的一声令下，每个物质粒会与其右边的物质粒合并，噗！两者都湮灭。
