Probes in time-space

　 　Time and space is a focus that numerous scientists and philosophers research and argue. Newton said: in the physics, space-time is a physical measure which is sure not to change with object’s exercising, speed is just the embodiment of the relation between space and time. Bacon once said: the change of space-time is the greatest reformers. It presages that the old will be destructed while the new will be born, it presages opposing the tradition at the same time innovating it, lots of modern mathematicians got the result that time is a constituent part of Fore basic virtues space through mathematical calculations on the basis of the theory of Einstein. Namely up and down, left and right, front and back, past and future. All the occurrence developing, growing, prosperous and decline of anything are the transitions of space-time point.

　　Time has long and short, space has big and small. This indicates that the space-time forms of any special object are opposite. But it’s absolute that all the differences of space-time between objects are different.

　　The characteristic of time is the eternal continuity, but there are many time and states during the continuity. The characteristic of space is extending continuously, but it includes many points-----places and areas. These explain that space-time is the “opposite-unities” of continuity and intermittent nature. Continuity is absolute, intermittent nature is opposite. The absolute continuity existed in the opposite intermittent nature.

　　Time is invisible and the space is visible. People often express the time by some characteristic, change and relation of the space. Without space, time can’s be expressed and ascertained. For example, “a day” means one rising and one setting of the sun; “a month” means one circling and one lacking of the moon. The time-expressed of moon and sun is expressed by the two objects of the moon and the sun.

　　In the modern life, whether the certainty of space-time is accurate or not decides the success or failure of the affair. Knowing the variety regulation of space-time is a knowledge that every decision maker must master.
