The Definition of Spacetime

About the Book

This book is about the definition of space and time. I used the idea of frozen universe to define a section of time in between two events. Then I created two events to describe an absolution stationary point of the universe. I also introduced Tang, Ke-Yun, the scientist who proved that the speed of gravity is the speed of light, and Stephen Hawking, the wonderful physicist of USA.
