宋代超新星爆发事件与光速不变原理 - He pointed out that , according to the principle of constancy of light velocity , the length of an object in the direction of its movement looked shorter when relative speed of the object was high enough
对这一论点谁也没有产生过怀疑，但有一个人对此首先发难，他就是爱因斯坦。本世纪初1905年，爱因斯坦提出：当物体的相对速度较大时，这个物体沿运动方向的长度“看上去”会变短。
