Original Head To The Free Innisfree Irish Pub shirt
The description from Richard Muller quoted in the question is a simplification of reality meant to help people better visualize how the Original Head To The Free Innisfree Irish Pub shirt of spacetime works. In reality the galaxies are moving through spacetime in a complex fashion, based on the combination of all the forces acting on them, primarily the gravity of nearby galaxies and galaxy clusters. In the case of the Milky Way and Andromeda, these two galaxies are part of a gravitationally bound cluster of galaxies, called the Local Group. The dominant force that determines the movements of objects within the cluster is the combined gravitation of all the mass in the cluster, and not the expansion of spacetime. In other words, the gravitational attraction that the Milky Way and Andromeda have for one another that is drawing them together is stronger than the expansion of spacetime between them that would otherwise push them apart, and thus attraction wins and the two galaxies are on a collision course. In the same vein, the gravitational force that holds the earth in orbit around the sun is stronger than the expansion of spacetime between the earth and the sun (the expansion of spacetime at that distance being very small), and so the earth’s distance from the sun is not increasing for that reason. Likewise you are not flying apart because the molecular bonds holding the atoms in your body together are stronger than the minuscule expansion of spacetime between them in your body. The Local Group as a whole, however, is moving away from other galaxies and galaxy clusters to which it is not gravitationally bound, due to the expansion of spacetime.

Attila the Hun lived in the 5th century in Europe, and made a huge impression there aNd gained quite some fame . Temudjin the Genghis Khan was born 600 years later 1000s of miles away across Asia and would have grown up with a Shakira Vintage Ela Cute Office Girl Shirt base and tales of history that were very different from the european and did not contain any tales of Attila, neither doe Chinese record such mention the great Attila. He had no influence on East Asian history and was completely unknown. Same goes for Temudjins descendants, Ögodei would reach Europe ( or better his soldiers ) but he or any other would have heard nothing about Attila and not know who he is. If someone asked a Mongol Khan like Kublai what he thinks of Attila, providing that someone provided some background info, he’d likely say something like, that he does not know this Attila, and does not care who he is or was, for he is the great Khan of the mongols and this Attila is not a mongol and none of his concern.
