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

个可能没有反的费密是什么？

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

因此，你每小释放百八十个反，每天大约四千个。

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种。

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个问题。

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个新，反就会相应地产生或消亡。

His prediction and the subsequent discovery of antimatter confirmed that every particle in the universe has a corresponding antiparticle.

他的预测和随后反物质的发现证实了宇宙中的每个都有相应的反。

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。

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

) 可能存在由反构成的整个反世界和反人。

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

不久之后，每十亿个和反，就有个额外的。

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。

And I've seen this one in anti-clockwise All right, so antiparticles are those that are against particles.

我看过这个逆针的 好吧，所以反是那些反对的。

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对和反，只为了在瞬间之后相互湮灭。

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

第个反是美国物理学家卡尔·安德森在1932年发现的。

P, and T. The symmetry C means that the laws are the same for particles and antiparticles.

P 和 T。对称性 C 意味着和反的定律相同。

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

在实践中，获得反是项非常耗、复杂和昂贵的工作。

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，物理学家不仅能得到反，而且能得到整个反原、反氦和反氢。

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，我们也需要找到种方法回到遥远的过去。

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。

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

每每刻，都有无数的夸克，和它们的反敌人起出现，然后进行激烈的搏斗，并在瞬间就互相湮灭。

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都对和反的失衡有着重要的作用。至少，这就是数学所讲的。
