时空问题作为物理学最基本的问题,是人们最为关心的问题之一,然而看似习以为常的时间与空间却是如此的复杂与奇妙。本文主要以物理学的发展为主线,从人类对时空认识的发展出发,详细讲解了关于时空的常见疑问、牛顿前时空观、牛顿时空观、狭义相对论时空观、广义相对论时空观、时间的不可逆、时空旅行和宇宙的有限与无限等问题。
As the most basic problem of physics, the issue of space-time is one of the most concerned issues of people. However, the seemingly commonplace time and space are so complicated and fantastic. Based on the development of human’s understanding of time and space, this dissertation explains in detail the common questions about space-time. Newton’s previous time-space view, Newton’s time-space view, special relativity theory’s time-space view, general relativity’s time-space view, time irreversible , Time and space travel, and the finite and infinite issues of the universe.
