The Andromeda Galaxy is estimated to be 2.57 million light years away and 260,000 light years in diameter. The size estimation of the Andromeda super massive black hole is 140 million times larger than our sun, while our own Milky Way galaxy black hole is only 2.857% as massive at 4 million solar masses.
Is time passing at a 2.857% relative rate as to the passage of time on Earth in Milkyway galaxy? That would be equivalent to 10.428 Earth days passing in Andromeda for every year experienced on Earth, a form of time dilation.
How is this time dilation skewing the observable light coming from Andromeda? We currently experience a blue doppler shift while observing Andromeda, which we have traditionally assumed indicates that the object is moving towards us.
Could time dilation from a larger galaxy experiencing a slower rate of relative time cause doppler shifting in observable light?
OR
Does the size of the black hole only determine the distance of the diameter of a local gravity well, while the rate of black hole rotation determines total galactic relative space/time dilation?
