本文以具有代表性的辩证唯物主义哲学时间观和相对论时间观为例,结合对时间概念的分析和探讨,论证了时间是表述物质存在和运动过程的始终及持续性的物理量——这一定义的客观性。并且按照这一定义解析了霍金的“奇点定理”。认为“奇点”并不就是物质,物质也并不就是“奇点”。因此,“奇点定理”证明的“奇点时间”的开始与终结并不就是物质证明的“物理量时间”的开始与终结。 In this paper, taking the dialectical materialist philosophical time view and the relativistic time view as examples, this paper analyzes and discusses the concept of time and argues that time is the consistent and persistent physical quantity that expresses the existence and movement of matter. Objectivity. According to this definition, Hawking’s “singularity theorem” is analyzed. That “singularity ” is not material, material is not “singularity ”. Therefore, the start and end of “singularity time ” proved by “singularity theorem ” are not the beginning and the end of “physical quantity time ” of material proof.
