Prove this.
Because in DB we know that RoSaT exists as a parallel dimension to the earth, as Goku himself told Gohan in DBZ, while in Bleach it's not.
I told you above that RoSaT isn't like Garganta but for some reason, you are repeating the same thing.
Not me, it's Tokinada who is trying to explain to Aura that Garganta works like outer space, blame Tokinada and Narita.
"If the world of the living and the Soul Society could be
likened to planets and the pipeline that connected them were Dangai, the
void of space that surrounded those was called Garganta."
So yeah Garganta works like an outer space that surrounds those dimensions.
Even in the same panel that Kisuke made, the dark space around the dimensions is said to be Garganta.
Yeah, I actually cant believe that I'm explaining something which is like basics in Bleach that everyone knows, Garganta isn't like RoSaT, it's stated to work as outer space by Tokinada who knows better than you lol.
