Abstract

Four-vectors are defined analogously to three-vectors and provide a compact means of presenting mathematical results in relativity theory. However, the four-velocity vector does not have the same physical significance as the three-velocity vector, but assuming so has led to the declaration that there is motion through spacetime which explains special relativistic time dilation. It is shown that four-velocity cannot legitimately be employed in this manner and that the time dilation effect does not require any motion through spacetime nor any speed through time.
狭义相对论中的速度和时间
四向量的定义类似于三向量,并提供了一种简洁的方法来表示相对论中的数学结果。然而,四速矢量与三速矢量的物理意义不同,但假设如此,就可以宣布存在穿越时空的运动,这解释了狭义相对论的时间膨胀。结果表明,四速度不能合理地以这种方式使用,时间膨胀效应不需要任何穿越时空的运动,也不需要任何穿越时间的速度。
