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

一个反粒子是美国物理学家卡·安德森在1932年发现的。

What is the only fermion that may not have an antiparticle?

唯一一个可没有反粒子的费密子是什么？

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.

在宇宙的一声令下，每个物质粒子会与其右边的反物质粒子合并，噗！两者都湮灭。

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

空间中的量子涨落在无时无刻地创造一对粒子和反粒子，只为了在瞬间之后相互湮灭。

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

可以测它们与对应反物质的异同，这可以帮助我们了解宇宙的本质。

If you map them back to the original circle, standing to the immediate left of those final matter particles or the immediate right of final antiparticles means you'll reach this endgame state and survive.

如果你把它们映射回原来的圆圈，站在最终物质粒子的左侧或是最终反粒子的右侧，你就走游戏终局并生存下来。

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，物理学家不仅反粒子，而且整个反原子、反氦和反氢。

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子和物质与它们的反物质的异同。

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.

2022年，科学家们计划建造一个便携式反粒子装置，然后用卡车把反物质开几百米外的另一个地点进行进一步实验。

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子，反粒子就会相应地产生或消亡。

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

不久之后，每十亿个粒子和反粒子，就有一个额外的粒子。

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

毕竟，当反粒子遇粒子时，就会发生所谓的湮灭。

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反粒子，我们也需要找一种方法回遥远的过去。

) There could be whole antiworlds and antipeople made out of antiparticles.

) 可存在由反粒子构成的整个反世界和反人。

A particle has the same mass as its corresponding antiparticle but opposite charge.

一个粒子与其对应的反粒子具有相同的质量但相反的电荷。

1932 American physicist Carl Anderson discovers the positron, antiparticle of the electron, in cosmic rays.

1932年，美国物理学家卡·安德森在宇宙射线中发现了正电子，即电子的反粒子。

Although the net energy of the pair is still zero, this can cause a violation of energy conservation, but this is theoretically allowed because the particle and antiparticle annihilate each other  within a time window provided by the energy-time Heisenberg principle.

尽管粒子对的净量仍然是零，但这可会导致量守恒的违反，但从理论上讲这是允许的， 因为粒子和反粒子会在由量-时间海森堡原理提供的一个时间窗口内相互湮灭。

And so this idea that there's an antiparticle came from the simple math, you know, there's a plus and a minus from the Dirac's quote-unquote mistake.

因此， 存在反粒子这一概念源于简单的数学原理，即从狄拉克所谓的“错误” 中出的正负关系。

And perhaps the stuff that falls in can, in a way, be thought of as the antiparticle of the Hawking radiation which came out.

也许落进去的东西可以被认为是以某种方式是霍金辐射的反粒子。

So now if I add the colour charges to the standard model diagram along with all the antiparticles, we get this.

因此， 若将色荷与所有反粒子一并加入标准模型图表中，我们便这样的结果。
