From Wikipedia, the free encyclopedia
Philosophy of space and time is the branch of philosophy concerned with the issues surrounding the ontology, epistemology and character of space and time . While such ideas have been central to philosophy from its inception, the philosophy of space and time was both an inspiration for and a central aspect of early analytic philosophy . The subject focuses on a number of basic issues, including—but not limited to—whether or not time and space exist independently of the mind, whether they exist independently of one another, what accounts for time's apparently unidirectional flow, whether times other than the present moment exist, and questions about the nature of identity (particularly the nature of identity over time).

Space
From Wikipedia, the free encyclopedia
rticle is about the idea of space. For the space beyond Earth's atmosphere (as in astronomy and spaceships), see Outer space . For all other uses, see space (disambiguation) .
The idea of space has been of interest forphilosophers and 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. Science considers space to be a fundamental quantity (a quantity which can not be defined via other quantities because other quantities - like force and energy - are already defined via space). Thus an operational definition is used in which the procedure of measurement of space intervals (distance) and the units of measurement are defined. Because this is the only available in science definition of space, then all known properties of space follow from this very definition.
