I said, "We didn't pass through each other because elementary particles have mass and because the space between elementary particles is filled with the binding energy that also has the properties of mass, and we've known that for 800 years."
我说，“我们没有穿过彼此， 是因为基本粒子有质量， 而基本粒子之间的空间 充满着结合能， 同样具有质量特征， 这道理我们800年前就懂了。”
