Of course not. I think you're taking what I said a touch too literally... or perhaps I didn't elaborate enough.

There's absolutely zero possibility that that attack wields the power of the Big Bang. There are bios about it, and they've never called it as powerful as the Big Bang. It's just Ki.

Supernova, on the other hand, has no bio. At least not to my immediate knowledge. Plus, it has a possibility of being a supernova—it has the explosion part. Every language's name for it seems to imply that...

Yeah, so it likely is one.

Unlike Vegeta's Big Bang Attack, Supernova has no bio to contradict it, no author statements to explain it, no explanations about it in the game itself (all three of which the Big Bang Attack have), and nothing to explain what it is or does.

Except one thing. Its names. All of which point towards relationships with stars.

Does its looks contradict it? Not really. A supernova is an explosion, correct? Well, so is this attack.

The Big Bang was an expansion of a singularity, correct? Well, is Vegeta's ball of Ki an expanding singularity? No.

Hence, my judgment.
