Time and space view of dialectical materialism;

1. Time and space are the existing forms of moving matter, time is the continuity and sequence of the material movement process, and time has the characteristics of one dimension. Space is the vastness and vastness of moving matter, and its characteristics are three-dimensional. The inseparability between time and space and material movement shows the objectivity of time and space.

2. The absoluteness and relativity of time and space. Time and space are absolute and relative unity, which contains two meanings:

1. Invariance of objective reality in time and space and variability of specific features. As the existing form of material movement, time and space are immutable and unconditional, so they are absolute; The specific characteristics of time and space restricted by the characteristics of material movement are variable and conditional, so they are relative; People's concept of time and space is also changing and developing, so it is relative.

2. The infinity and finiteness of time and space are dialectical unity of infinity and finiteness. The material world is infinite in time and space, while the time and space of specific things are limited, temporary in time and bounded in space.
