The concept of space is considered to be of fundamental importance to an understanding of the [/size][url=https://algassania2.mam9.com/wiki/Universe][u][size=25][color:f8e5=#0000ff]universe[/u][/color][/size][/url][size=25] although disagreement continues between [/size][url=https://algassania2.mam9.com/wiki/Philosophy][u][size=25][color:f8e5=#0000ff]philosophers[/u][/color][/size][/url][size=25] over whether it is itself an entity, a relationship between entities, or part of a [/size][url=https://algassania2.mam9.com/wiki/Conceptual_framework][u][size=25][color:f8e5=#0000ff]conceptual framework[/u][/color][/size][/url][size=25].
Many of the philosophical questions arose in the 17th century, during the early development of [/size][url=https://algassania2.mam9.com/wiki/Classical_mechanics][u][size=25][color:f8e5=#0000ff]classical mechanics[/u][/color][/size][/url][size=25].
