Hubbell Motion Sensors Hubbell Constant? Are Galxies Recession Velocities Observed As Radial Motion Or Orbital Motion?

Hubbell constant? are Galxies recession velocities observed as radial motion or orbital motion? - hubbell motion sensors

If the radial motion away from us - would orbit a central point that the universe (gravity, at least) - Despite galaxies tend to have identified a speed that is within their group.
