Fun, I can tell you, because I've marched that far, although, I doubt I'm the first to march that far although the others may have other means of transport than marching. Usually one receives instruction, they don't just go marching madly into the distance because of the density and relative size of your soul. So, in order to have privacy and its own information, the Son called for light. The Holy Spirit also has its own information, sound. Smell is of the Misfit, touch the Scoundrel and taste the First Avatar. These surround the origin. The primary scientific proof that Jesus Christ is God's son, Baladeva. So, the Father can see any distance, inside the Singularity etc. Besides this etheric substance has no mass. How can you have a substance with no mass? Easy, the Father, or Son says, let's make some, there it is without mass. So, in ether one may travel faster than light. That's how all the aliens do it, but it carries its own set of dangers, i.e. becoming solid.
So, the first correction we need to make is that of a solid Universe. The Universe is a thin spherical sheet. Thin to the radius of the balloon, pretty big in observable Universes, in ou. It's not very far to the edge, we're near center, and I estimate if the ou is one millimeter, then the band is a meter wide. Beyond the final realms, the last central star a region of dust exists and we march into it, for two weeks.
The faster you go the tinier you get, so that you cover less distance, but if you keep on, you come to the representation of quasars, and find two more sets. Around the thin spherical sheet of the Singularity are two etheric shells of increasing pattern density, each enclosing about another volume to the Singularity. There is time to gauge the volume of the shells, but not a second try. One doesn't march to the Singularity, it is a jump from half-space where the tiny contests occur. Once the genie has attained the Singularity, it may retire from its tiny contests, they are no-longer such to it, they didn't take him halfway there, from the electron. So, Singularity surround the inner and outer surface of the Universe. Which must add thickness in concert with the expanding bubble.
Supposing the Universe is 27 gyrs old and that it is 6:00am, then time between Big Bangs is 108 gyrs, and since we're near the middle I would expect the observable Universe to continue up to 300 gyrs. Another, rare scenario is that the Cosmic Manifestation explodes. Then I would imagine your calculations pan out, any civilization hoping to survive would eventually want to find some of the other Cosmic Manifestations hovering over the etheric planet in a Universe in a Cosmic Manifestation through compounds to the (shh) upturned, tortoise. The next event horizon is at the Creation. The wall of the Cosmic Manifestation is about a two-week march. We may be moving at an accelerating rate, faster than Krishna as you, always up absorbing the next layer, never time to stop and enjoy the vision or company. For twenty years without getting to the frog eggs orbited by the Great White Throne.
If too much mass is added at the end, the mass will fill the first shell, then the second, drawing the remaining mass into the first shell leaving an empty Singularity with sufficient mass to condense. Upon such a miscalculation, the entire Creation is upturned and dumped down the pit. A certain number of frog eggs combine in a Causal Big Bang or rarer Condensation.
