Publisher's Synopsis
The physical and philosophical concepts of space, highlighting their infinite, ever-changing nature
Physical space
Physical space is the place where objects and forces are located. It is a three-dimensional space, with length, width, and height. Physical space is infinite and is constantly expanding.
To describe physical space, scientists use the theory of relativity. According to this theory, space and time are intertwined in a single, cross-linked matrix called "spacetime." Physical forces are produced by the curvature of spacetime. For example, gravitational force is produced by the curvature of spacetime.
Philosophical space
Philosophical space is a broader concept than physical space. It includes the three dimensions of physical space, as well as other aspects such as time, identity, consciousness, and knowledge.
Philosophical space is infinite and ever-changing. It is an integrated system, in which all things are interconnected.
Infinity
To say that space is infinite means that there is nothing beyond it. There is no end to space, and it will always continue to expand.
Infinity is a complex concept. It is difficult to understand, because the world we experience is small and limited.
