| Oct 9, 2021 at 3:01 | comment | added | Edouard | In "Many Worlds In One", Vilenkin remarks that expansion differs from relative motion. However, as quoted in their preprint whose main title was "Expanding Confusion", Davis (of Lineweaver and Davis, cited in Pulsar's answer) had rejected the physicality of "spatial expansion" as any sort of force or drag. I'm making this comment mainly to help myself find Oktay Dogangun's helpful comment & Pulsar's answer, whose color-coded diagram is easier to follow than a couple of the 3 panels in Lineweaver & Davis's paper. | |

| Apr 15, 2018 at 8:48 | comment | added | Oktay Doğangün | The expansion hasn't got a speed. It is a misnomer to say that it is a speed. It should be called expansion rate. It is not like two points having a relative speed, it is more like a scaling rate of the unit distance. If there were no masses in the universe we would not sense any expansion at all. | |
