Not withstanding his opinion ultimately aint canon at all and thus, ultimately ain't usable as evidence for, or against.
"—Oh, so there are worlds like Planet Namek out there! Because of all those suns it never gets dark on Planet Namek, but is that part realistic, too?
Sekine: Oh, that aspect is a bit far-fetched on a physical level. In systems with more than one sun, the smaller suns always orbit the largest sun.
Furthermore, the planets in that system would then orbit the suns, so no matter how many suns there are, the planets would still experience night at some point."
Does corroborate with what I was saying, it would actually be impossible as it would experience night eventually due to orbiting one such sun, that, or torn apart if each sun is equally contributing, kinda leading to, what if the suns orbit Namek instead? Kinda unrealistic but the very premise is, and when we have wild shit like the supreme kai planet which is asinine, idk, maybe.
Personally im 50/50, maybe as a high end? Like "possibly"? But then again, idk if this would even affect anything except Moro, who's like, low 2-C or some shit, shit like Frieza nuking the core or tanking it might not be calculable if we don't know how big said core is, or how close to the epicenter he was.
