The space discussed in this book is realistic physical
space, is defined as “extensive property of matter and its motion”. This is the
space we are familiar with in our daily life. Its basic property is it can be
measured and validated.
In physical theory, there are “phase space” in
statistical physics, “state vector space” in quantum mechanics, “complex number
space”, “function space” in mathematics, and some noosphere in social
scientific field. In Buddhism books, there are hells with eighteen layers,
heaven with ninety-nine layers. These are all abstract spaces.
We will not discuss these kinds of spaces.
With the knowledge of space from our daily lives, we
introduced a strict scientific definition of space and illustrated that space
is a property of matter. In this book, the relationship of uniformity of space,
centrosymmetry, law of momentum conservation and law of angular momentum
conservation are introduced. Also we discussed the relation of space and
motion, introduced special relativity and demonstrated that the space
properties of a matter will change dramatically as it is moving with a speed
close to the light velocity. We introduced the property of the smallest space
we can observe at present and quantum mechanics which describes the micro
world. Also we introduced the fact that gravitation will bend space of matter
and general relativity which described this fact. We introduced cosmology which
described the big space; about the related observed facts, related “standard
model” and its difficulties; the related works of the author and the supports
from observed facts. At last, this book introduced some thoughts on some
questions from the author. Some of them will be solved with development of
science later.
