The idea of '''space''' has been of interest for [[philosophy|philosophers]] and [[science|scientists]] for much of human history. The term is used somewhat differently in different fields of study, hence it is difficult to provide an uncontroversial and clear definition outside of specific defined contexts. Disagreement also exists on whether space itself can be measured or is part of the measuring system. (See [[#In philosophy|Space in philosophy]].)
