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

唯一一个可能没有反粒子的费密子是什么？

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粒子都有相应的反粒子。

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子，反粒子就会相应地产生或消亡。

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粒子，而且能得到整个反原子、反氦和反氢。

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

毕竟，当反粒子遇到粒子时，就会发生所谓的湮灭。

It's just one way of understanding how particles of matter may be similar to and different from their antiparticles.

这仅是从一方面来了解粒子和物质与它们的反物质的异同。

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

第一个反粒子是美国物理学家卡尔·安德森在1932年发现的。

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

不久之后，每十亿个粒子和反粒子，就有一个额外的粒子。

And observing how they are like and unlike their antiparticles could help us understand the very nature of the universe.

可以观测到它们与对应反物质的异同，这可以帮助我们了解宇宙的本质。

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

) 可能存在由反粒子构成的整个反世界和反人。
