Yeah, but they were just destroying the celestial bodies and shit, no? No erasing space itself.
With this revision being set that would be only universe level from now on in any case, as destroying universe + universe sized dimension isn't going to be Universe+ anymore.Isn't the afterlife just part of Universe 7 anyway?
Considering we later get DBS destroying the entirety of Hyperbolic Time Chamber, I think that renders it moot anyway and considering Super Buu and SSJ3 Gotenks being able to tear a hole through dimensions which would include space with their screams, pretty sure BoG would include them destroying space.
