- Using the same two initial arm lengths an angle of 90 degrees between them produces a third side which is the square root of 2 times the arm length. 使用最初的相等的两个手臂长度和之间的夹角为90度，可以产生第三条边，而变成等于2的平方根乘以手臂的长度。
- The usual version of this common question goes something like: "Yesterday you said that LIGO has 4km arms and that a gravitational wave makes the arm length change a little because space is distorted. 这个问题的常见版本类似于：“昨天你们说LIGO的臂长为4公里，然后在引力波扭曲了空间后这个长度改变了一丁点。
