Hi, From a retired thread I (roughly) quote the following: "To plot the path that a point on the Earth takes through space, you would need to calculate these movements: The Earth relative to the Sun. The Sun relative to the Galaxy centre. The Galaxy relative to the Local Group. The Local Group relative to the Super Cluster. The Supercluster relative to the Great Attractor." I was wondering - because of all of the various ways, directions and speeds at which any point on earth travels at the same time, would you say that each moment of a person's lifetime is spent at a unique point in space? Is there any literature on that subject? Also... how can an object (e.g, me) travel in so many different directions and speeds simultaneously?
