... so, Superman himself says he got it before it could fully release, right in the scan, yet you keep saying it broke free. This requires ignoring the actual scan. If the field was not hindering it in any way, and this is a "solar system destroying black hole", if it actually broke free, why are anyone in the JLA besides Superman, since obviously he can tank solar system busting force, still alive? It broke free. You keep saying it broke free. There's even, as you admit, a panel of people being warped, showing Superman thus not getting to it before it "Broke free". Why is there still a solar system?
(unless, like Superman himself said, he got to it before it could fully release, which meant, by simple logic, it was still in part being held back. Which would mean there was a field still holding it back to some degree. Which we see the glow of. Which means Superman himself never held it unassisted by some force).
edit: I will put this as simply as it can be put. What is on the very next page after Superman grabbing the black hole. You don't even have to check the comic. The page was posted right in this thread.
