Great post thanks for sharing!!

My perspective: The universe is infinite; this means that there is not only infinite volume but also infinite mass filling that volume having an infinite variety, from infinitesimal through infinite in relative mass.

What this means is that there is no where beyond the mass where there is volume but not mass because there is already mass everywhere. As a result, mass doesn't just flow outward into those "empty" zones, filling the infinite empty space and reducing the universe to nothingness. It is able to stay stable with mass everywhere because there is mass everywhere. This holds it all in a general balanced equilibrium that allows for larger and larger structures to exist. Each larger structure forms a generally galactic structure of smaller masses around it, producing an endlessly larger but always generally "flat" structure such as the disc of a galaxy or the belts and planets of a solar system, which leads to us seeing it as flat.

At some point, the disc is so large that we--having limitations in how far our technology can see into this infinite space--no longer see these larger and larger structures. Also, gravitational lensing influences how we see the universe which plays a critical role in producing the interweaving web of superfilaments. Optical illusions begin to play a large part in how we see and position in 3-dimensional coordinates the physical location of systems, which leads us from being able to appreciate the disc structure of larger and larger systems since we are not accounting for gravitational lensing on such a large scale because we do not account for infinity in our current models.
