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

第一个粒子是美国物理学家卡尔·安德森在1932年发现的。

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

唯一一个可能有粒子的费密子是什么？

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

在实践中，获得粒子是一项非常耗时、复杂和昂贵的工作。

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

你如果很幸运粒子破坏，你就成为了未来星系中的子。

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·克就怀疑存在电荷相的粒子。

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，当粒子遇到粒子时，就会发生所谓的湮灭。

Scientists tried to answer this question by creating anti particles in laboratory.

科学家们试图通过在实验室制造粒子来回答这个问题。

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

) 可能存在由粒子构成的整个世界和人。

So the anti is that the charge flips.

所以粒子就是电荷转。

The virtual particles always appear and vanish in pairs  of a particle and an antiparticle.

虚粒子总是成对出现和消失，一对包括一个粒子和一个粒子。

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

一个粒子与其对应的粒子具有相同的质量但相的电荷。

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

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

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

粒子就是那些与粒子相对的粒子。

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

电子与它的粒子正电子一起产生。

So it's anti because the charge is different.

所以它是粒子因为电荷不同。

So that is a development of the idea there's particle, there's antiparticle, and so on.

这就是关于存在粒子、粒子等概念的发展过程。

ATLAS has now confirmed that these lead-nucleus collisions produce top quarks, together with their antiparticle counterparts.

阿特斯探测器现已确认， 这些铅核碰撞会产生顶夸克，以及它们的粒子。

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粒子，只为了在瞬间之后相互湮灭。

The reason is that the laws of physics are not quite the same for particles and antiparticles.

原因是粒子和粒子的物理定律并不完全相同。
