any reason as to why the afterlife should be side by side that isn't in secondary materia? when we see the universe we don't see then in there by the side
not really? do they have any size said in the main cannon?
okay so? then answer stays the same
mockery tone aside, these 2 in the op:
"some may bring up the fact that the other dimensions of the universe like the afterlife and the kaioshin realm are not visible in the map used in the anime, for that i say:
1.1: there is nothing to say that they would be visible in the first place, the only thing that would suggest that they would is the macrocosm map and the guides, which isn't a good counter since what it is shown in the main cannon always takes priority over secondary cannon like the guides, so they not appearing is not a counter argument since they have no stated size whatsoever in the main canon of dbs, and things like guides are only secondary cannon with anything of the main cannon taking priority over it
1.2: even if you want to hard take the dimensions as needing to be visible however, we can clearly see
multiple massive cosmic like objects in the map, so to say that some of them are the other dimensions is not too far fetched of an assumption, specially when we know that we are seeing the universe"
