In mathematics we can have an infinite number of points between two integers.

This is really circular logic since a point is defined as infinitely small.

Does a point exist anywhere in the physical world or is it simply a convenient mathematical abstraction with no place in reality.

Is space actually divided into infinitely small points? What about time?

A point doesn't really "exist" in mathematics either. It's the result of a limit. https://en.wikipedia.org/wiki/Cardinality_of_the_continuum – Brandon Enright Jun 01 '13 at 19:55
