If the Universe Is Closed and Finite Then
Informally a finite set is a set which one could in principle count and finish counting. A closed curve is thus the image of a continuous mapping of a circle. Is The Universe Infinite Or Finite Or Is It So Close To Infinite That For All Practical Purposes It Is Astronomy Com The number of elements of a finite set is a natural number possibly zero and is called the cardinality or the cardinal number of the set. . In mathematics particularly set theory a finite set is a set that has a finite number of elements. If the domain of a topological curve is a closed and bounded interval it is called a path also known as topological arc or just arc. There are two possible futures for our Universe continual expansion open and flat or turn-around and collapse closed. Current values for the critical density range from 01 to 1 which produces a new dilemma from. The description of the various geometries of the Universe open closed flat a...
