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

第个反子是美国理学家卡尔·安德森在1932年发现的。

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

唯个可能没有反子的费密子是什么？

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

空间中的量子涨落在无时无刻地对子和反子，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子破坏，你就成为了未来星系中的种子。

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，有无数的夸克子，和它们的反子敌人起出现，然后进行激烈的搏斗，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的圆圈，站在最终子的左侧或是最终反子的右侧，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，由于先进的技术，理学家不仅能得到反子，而且能得到整个反原子、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，科学家们计划建个便携式反子装置，然后用卡车把反开到几百米外的另个地点进行进步实验。

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

在实践中，获得反子是项非常耗时、复杂和昂贵的工作。

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的东西对子和反子的失衡有着重要的作用。至少，这就是数学所讲的。

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

早在1928年，英国理学家保罗·狄拉克就怀疑存在电荷相反的反子。

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

每次科学家或摧毁个新子，反子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，你每小时释放百八十个反子，每天大约四千个。

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

) 可能存在由反子构成的整个反世界和反人。

So the anti is that the charge flips.

所以反子就是电荷反转。

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

1932年，美国理学家卡尔·安德森在宇宙射线中发现了正电子，即电子的反子。

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

反子就是那些与子相对的子。

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

电子与它的反子正电子起产生。

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.

尽管子对的净能量仍然是零，但这可能会导致能量守恒的违反，但从理论上讲这是允许的， 因为子和反子会在由能量-时间海森堡原理提供的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，光子会分裂成个电子和个正电子，正电子基本上是电子的反子——它具有相同的量但带有正电荷。
