Spacetime is potentially the combined information of all the infinite fields woven together or some role player in it, and we can see from gravitional waves that matter and gravity can interact with spacetime. With one interaction proven it is also possible that the density of spacetime and or all the fields is greater around supermassive bodies such as galactic center black holes or star clusters allowing for gravity to have a stronger effect on the formation and binding of galaxies than we’ve expressed with math based on spacetime and fields having no or the wrong value and function. The increased density would create a differentiation from galactic centers gravity and the edge of the galaxy, there’s already the relativity of time potentially an expression of field or spacetime density as the fields are information and energy and as denser closer to the black hole the information can be processed and transferred through states or through expressions up or down in direction giving us the increase in times duration as your closer to supermassive bodies. Because of density everything happens faster yet at the same relative rates. Any feedback is welcome just an aspiring theoretical astrophysicist trying to learn and grow. Thank you

It sounds like the idea is not matching what is observed, see https://en.wikipedia.org/wiki/Bullet_Cluster for instance. Observations of colliding galaxy clusters show, as far as I know, that the effects of gravity lensing is not necessarily aligned with the location of baryonic.
