Doesn't the second map (Economic centrer of gravity map) [0] depend on the projection you use? I.e. if you'd shift the map so that the Americas are in the middle of the picture, then wouldn't the "center of gravity" end up in the US?
And besides does the point make any sense at all? The world's economic center of gravity is currently somewhere in northern Russia.
The movement on the hand tells a clear story of forming circle where the world's economic activity returns to Asia from a short trip to Europe and USA.
The movement is maybe less dependent on the projection.
No, it shouldn't. The caption says it the center of mass was calculated in 3D then projected onto the closest surface point. Changing the projection used wouldn't change the position of this point.
My reading of the caption is that they projected the 3d center of gravity out to or down onto a 3d surface of the earth (along the line connecting the center of gravity to the center of the planet).

Yes. I think that there are some problems there.
