In particle beams, on average, they last for 14 minutes and 48 seconds before they decay into protons.

在粒子束中，它们平均会持续 14 分 48 秒，直到衰变成质子。

While particle beams heat it to temperatures hotter than the sun's core.

而粒子束将它加热到比太阳核心还要热的温度。

That isn't empty enough for scientists who work on experiments, like the Large Hadron Collider, where particle beams need to circulate at close to the speed of light for up to ten hours without hitting any stray atoms.

对于从事实验的科学家来说，这还不够空，例如大型强子对撞机，粒子束需要以接近光速的速度循环长达 10 小时，而不会撞击任何杂散原子。
