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

第一反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?

唯一一没有反的费密是什么？

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

在实践中，获得反是一项非常耗、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.

你如果很幸运没被反破坏，你就成为了未来星系中的。

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

早在1928年，英国物理学家保罗·狄拉克就怀疑存在电荷相反的反。

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

不久之后，每十亿和反，就有一额外的。

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

毕竟，当反遇到，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反来回答这问题。

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

) 存在由反构成的整反世界和反人。

So the anti is that the charge flips.

所以反就是电荷反转。

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

虚总是成对出现和消失，一对包括一和一反。

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

一与其对应的反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，美国物理学家卡尔·安德森在宇宙射线中发现了正电，即电的反。

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

反就是那些与相对的。

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

电与它的反正电一起产生。

So it's anti because the charge is different.

所以它是反因为电荷不同。

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

这就是关于存在、反等概念的发展过程。

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

阿特拉斯探测器现已确认， 这些铅核碰撞会产生顶夸克，以及它们的反。

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无刻地创造一对和反，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.

原因是和反的物理定律并不完全相同。
