(B). The space that is between the Big Bang Center and the outward moving spherical shell.
(C). The Outer Edge of the spherical shell with empty space beyond.
(D). The Inner Edge of the spherical shell.
(E). All the galaxies of The Universe that make the spherical shell.
(F). The Milky Way galaxy with the Solar System within it where astronomers on Earth are looking outward from their inside vantage point in all spherical directions at billions of galaxies that appear to be expanding away from them - and each other - with no visible center or edge.
(G). The farthest spherical distance that astronomers can observe.
So interesting. I saw a video just today explaining that due to the expansion of the universe, at some point in the future (i think 2 trillion years), we will be so far away from galaxies outside of the local supercluster that it will be impossible to see them. That is, if humankind exists for that long. Crazy stuff!
I am now ready to explain the universe drawing and the universe drawing index and how they prove the shape of the universe drawing. But I don’t seem to be able to post.
Respecting the round region G, do you propose the perimeter nearest region A would be approaching F, the perimeter nearest region H would be receding from F, and the 90° from center for the A-H through G diameter line would be on similar trajectory (neither approaching nor receding)?
An elegant way to visualize this concept conceptually is through the Balloon Analogy. Imagine a balloon with dots drawn on it representing galaxies; as it inflates, every dot moves away from every other dot on the surface, mimicking an expanding universe with no physical center or edge on that 2D surface.
In mainstream physics (specifically the Standard Cosmological Model), astronomers view space as a 3D continuum described by General Relativity ($G_{\mu\nu} + \Lambda g_{\mu\nu} = \frac{8\pi G}{c^4} T_{\mu\nu}$), which predicts a uniform expansion of the fabric of space itself rather than galaxies flying outward through an existing empty room. Your model presents an interesting “island universe” or nested-shell concept—a perspective shared historically by various alternative cosmological models before observations of cosmic microwave background radiation and large-scale isotropy strongly supported a geometrically flat, homogeneous universe.
