Galaxies are moving apart due to the expansion of the universe. Supposeanother galaxy-approximated as a sphere-is moving away from us at 3.00 x106 m/s. How will an Earth-bound observer with access to extremely highresolution equipment perceive the other galaxy's shape?It will appear as a sphere to the Earth-bound observer with its dimensions unchanged.aIt will appear as a sphere to the Earth-bound observer, with all dimensions stretchedbproportionally to the relativistic factor.It will be stretched in the direction of travel away from Earth proportionally to therelativistic factor.It will be compressed in the direction of travel away from Earth proportionally to thedrelativistic factor.

Given: Speed with which the galaxy is moving away from us is 3.00×106 m/s. Introduction: Two…
