Inside a baryon like a proton, the three light quarks are pretty evenly balanced and zip around each other.

在像质子这样的重子内部，三个轻夸克非常均匀地平衡并相互环绕。

When two of the quarks are heavy, physicists expect that the lighter quark will circle around them, kind of like a planet around a binary star system.

当两个夸克很重时，物理学家预计较轻的夸克会围绕它们旋转， 有点像双星系统周围的行星。
