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

第一个反粒是美国物理学家卡尔·安德森在1932年发现。

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

唯一一个可能没有反粒费密是什么？

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

空间量涨落在无时无刻地创造一对粒和反粒，只为了在瞬间之后相互湮灭。

If you're lucky and avoid being destroyed by antimatter, you'll be the seed of a future galaxy.

你如果很幸运没被反粒破坏，你就成为了未来星种。

Every moment, countless quarks pop into existence, along with their anti-particle enemies, before doing furious battle and annihilating each other in an instant.

每时每刻，有无数夸克粒，和它们反粒一起出现，然后进行激烈搏斗，并在瞬间就互相湮灭。

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圆圈，站在最终物质粒左侧或是最终反粒右侧，你就能走到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，由于先进技术，物理学家不仅能得到反粒，而且能得到整个反原、反氦和反氢。

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反粒装置，然后用卡车把反物质开到几百米外另一个地点进行进一步实验。

In practice, obtaining anti particles is a very time-consuming, complex and expensive undertaking.

在实践，获得反粒是一项非常耗时、复杂和昂贵工作。

Turtles? Whatever... Look, all that's required for the creation of matter an imbalance of particles and anti-particles. At least, that's what the math says.

海龟？不管怎么样.....你想，所有这些宇宙形成所需东西对粒和反粒失衡有着重要作用。至少，这就是数学所讲。

Back in 1928, the British physicist Paul Dirac suspected the presence of anti particles with an opposite electric charge.

早在1928年，英国物理学家保罗·狄拉克就怀疑存在电荷相反反粒。

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，反粒就会相应地产生或消亡。

Thus, you emit 180 anti particles per hour in about 4,000 per day.

因此，你每小时释放一百八十个反粒，每天大约四千个。

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

) 可能存在由反粒构成整个反世界和反。

So the anti is that the charge flips.

所以反粒就是电荷反转。

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

1932年，美国物理学家卡尔·安德森在宇宙射线发现了正电，即电反粒。

Alright, so anti-particles are those that are against particles.

反粒就是那些与粒相对粒。

An electron is created alongside its anti-particle, the positron.

电与它反粒正电一起产生。

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.

尽管粒对净能量仍然是零，但这可能会导致能量守恒违反，但从理论上讲这是允许， 因为粒和反粒会在由能量-时间海森堡原理提供一个时间窗口内相互湮灭。

Sometimes, the photons split into an electron and a positron, which is basically the opposite of an electron – it has the same mass but a positive charge.

有时，光会分裂成一个电和一个正电，正电基本上是电反粒——它具有相同质量但带有正电荷。
