“I am always struck by the centrality of the observer’s position. He always stands fronting the middle of the arch, and does not suspect at first that a thousand observers on a thousand hills behold the sunset sky from equally favorable positions.”
Perspective is of course relative. The reality of what one sees might even be – Einstein theorized just looking changed things – making keeping it real all the more arbitrary.
