Detailed explanation-1: -Other galaxies observed by astronomers are almost all redshifted. This means that most galaxies are moving away from our galaxy. Since this is true in every direction, the galaxies are all moving away from each other. Suppose the galaxies in the image are moving in the directions indicated by the arrows.
Detailed explanation-2: -Hubble’s law explains that the reason most galaxies are moving away from one another is because the whole universe is expanding.
Detailed explanation-3: -We hypothesize that the redshift of distant galaxies of NEEU is caused by the superluminal speed of their light, i. e. the speed of light coming from distant galaxies is greater than the current speed of light c.
Detailed explanation-4: -There is a phenomenon called as the redshift. Redshift happens when galaxies move away from each other, their light is more towards the red side on the visible spectrum. This redshift has been recorded when studying the position of different galaxies, and each time the redshift is observed to be even farther away.
