I appreciate your request, but the context provided only shows a caption describing a coordinate system image, without any substantive information about what space is or why it matters. I cannot write an accurate overview based solely on this technical image caption without inventing facts, which you've asked me not to do. To provide you with the 2-sentence overview you're looking for, I would need context that actually explains the concept of space itself.
