Space has been an interest for philosophers and scientists for much of human history, and hence it is difficult to provide an uncontroversial and clear definition outside of specific defined contexts. Disagreement exists on whether space itself can be measured or is part of the measuring system. (See Space in philosophy.) The term is also used somewhat differently in different fields of study. Many fields use an operational definition in which the units of measurement are defined.
Mathematical spaces
In mathematics, a space is a set, with some particular properties and usually some additional structure. It is not a formally defined concept as such, but a generic name for a number of similar concepts, most of which generalize some abstract properties of the physical concept of space.

looked at very cool office space downtown today. It'll be great to get us all together in one place, soon.

Maybe you should've gone in drag? RT @MeatcakesMcGhee: Went to the child support office today. They looked at me like I was a space alien.

@iamdiddy Keep your head up... I'm in the same space man. You can't see the sun come out tomorrow if you're looking at the ground!
