We said that the “centre of the world” is a notion which always stems from social construction, from human perception and not from a physical reality. In this regard we do know, today, that Jerusalem is not a physical centre of our Planet; unless we followed the idea that all points of the Planet are its centre: so Jerusalem would be one out of an infinity.
Jerusalem is at the centre, if not the physical, at least the symbolic one of our World. We know that, in respect of the world’s shape, its “centre” stems from social construction and choices, and not “natural” or physical reasons. One famous map, Bunting’s Cloverleaf Map of the World, is a good example of this socially-constructed centrality.
