Basically yes; entirely no. I have to trust the math, because I can not do it. If the math is in error, that would be the reason for a counter argument. The math is good I’m sure, so I scim past the equations that I am not capable of solving. I do understand it does not address what I am proposing. It is another notion entirely. Most Interesting to me is that it shows there is no consideration, or comparison of the effects that Gravity Time Dilation will show between the Schwarzschild radius vs. 5000 ly 10,000 ly/ 25,000 ly/ 50,000 ly, etc. even at this level of mathematical modeling. I am currently learning, outlining and gathering observable data, to be able to show a comparative analysis of this effect at several locations radially throughout Andromeda. I am gathering the needed parameters, but there are many things to consider, before even starting the calculations. First and foremost, Gravity Time Dilation ‘can’ account for Redshifts anywhere between Zero and 3.00, or 300,000 Km/s. This would be clear at the event horizon of a Supermassive Black Hole, such as is theorized currently within the galactic cores of spiral Galaxies. From that point outward the Time Dilatation will dilute, but as too how fast, and how far the effects need to be considered is the question. One consideration is of course the initial mass estimated within the event horizon. The initial density is the biggest factor when considering the maximum value for Time Dilation of a single object orbiting nearby (nearby might be within 5 ly’s). Due to the Gravitational Time Dilation equation, the density of the core has the largest impact, because it is radius, over mass. The closer we are to the center of an orbited object vs. its mass, the more exponential the effect. This is reduced by an inverse square, simply meaning that as we travel twice the radius, the effects quarter, exactly as any other Gravity field equation. We need a best estimate of the surface radius so we can use an initial mass, then we can do the calculations outward from there at several benchmarks. Andromeda’s Black Hole is currently estimated at 4.3 Million Solar Masses. We could actually use the Gravity Time Dilation equation to determine the radius of this Black Hole, by finding at what radius this mass can keep at the speed of light. The effects of this will drop of rather rapidly as we travel outward from the galactic core, but another estimate would need to be made of the ‘new’ total mass contained within the radius of any object’s orbit that we observe. The overall mass within that sphere becomes the new mass that should be used to deduce the total effects of Time Dilation from light emitted from a particular object. Though our initial mass 4.3 million Solar Masses, and not the density, will determine the overall ‘reach’ of the Black Hole’s Gravitational Time Dilatation/Redshift for a particular object, the successively added masses within each specimen’s orbit will increase at each benchmark radially. For instance, another radius we might consider while calculating for a single orbiting object would be that of the galactic bulge, roughly 5,000 ly. The total mass within that orbital sphere would be around 1.67 Billion Solar masses. This is the new Mass to Calculate from that radius, and so on. Even some of the mass located outside that particular orbital sphere, would add to the equation, but not to show what is needed to prove what I am trying to show here. It will be close enough without adding this to the complexity initially at least.
