Even the Nazi's wouldn't try to put Akira's work down. How low have you fallen, KingH?
Planets have been nothing since DB chapter 187, page 5 when vegeta declared, when weakened and I quote "I will destroy this world and everyone on it!!!" They are only limited, on lower levels (Pre-Frieza appearance) by how much they can manifest, but their power is so overwhelming by that point that destroying worlds, Suns, planets are such casual acts it's a shame to even put that as a limit or a substantial feat. It'd be like popping a balloon for us, for Captain Ginyu to destroy a world.
SSJ 2 Goku/SSJ3 Goku move so quickly, they constantly find themselves entering in different realities where the same outcome is happening, just slightly different. Which is why Goku does not lose, but that's another theory for another time. Goku moves 3.6789 million times the speed of light in SSJ3, yet alone God form.
It's simple algebra. Goku+SSJ3+The fictional world-Morals=Devastation we've never been meant to witness.
