Space is the boondless three-dimensional extent in which objects an events hae relative poseetion an direction. Pheesical space is eften conceived in three linear dimensions, altho modren pheesicists uisually consider it, wi time, tae be pairt o a boondless fower-dimensional continuum kent as spacetime. In mathematics, "spaces" are examined wi different nummers o dimensions an wi different unnerlyin structurs. The concept o space is considered tae be o fundamental importance tae an unnerstandin o the pheesical universe. However, disagreement continues atween filosophers ower whether it is itself an entity, a relationship atween entities, or pairt o a conceptual framework.
