can anyone please tell me what actually is the space? how big is it? and what is beyond it? who governs these planetary motions? is there some one like GOD?

Topology of a set X is the collection of sets such that
1) T contains the empty set and X.
2) T contains arbitrary union of elements of T.
3) T contains finite intersections of elements of T.

A subspace Topology of the subset Y of X is the collection of sets defined by:

\( T_y= \{Y \cap U: U \in T\}\)

Here is another joke:

Yes, there used to be. But GOD is DEAD! But behold, I teach you the Overman!
