Hubble's observation from redshift shows a pattern that the speed of the galaxies is proportional to their distance, by using those informations we can map the position of the galaxies.
But these observations were made just from Earth. So what I am asking is, do the observed distances between other galaxies other than Milky way (ie. distances between galaxyA , galaxyB and galaxyC) show that their velocities also follow Hubble’s pattern?
Are we certain that if we live in another galaxy, we will see other galaxies moving away from us following Hubble’s pattern? SoOr is it an assumption made just from observations on Earth that weevery point in the universe is the center?
So that I can rule out the idea that we see other galaxies moving away from us in that pattern because Milky Way is near to the center of the universe.
