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 對(duì)這一論點(diǎn)誰(shuí)也沒(méi)有產(chǎn)生過(guò)懷疑,但有一個(gè)人對(duì)此首先發(fā)難,他就是愛(ài)因斯坦。本世紀(jì)初1905年,愛(ài)因斯坦提出:當(dāng)物體的相對(duì)速度較大時(shí),這個(gè)物體沿運(yùn)動(dòng)方向的長(zhǎng)度“看上去”會(huì)變短。
