Let me see if I can explain this to you again.
1. Cyborg says "This thing will destroy the planet if it explodes".
2. Superman says "Not if I can help it."
3. Superman flies the thing into space.
4. It explodes while he is carrying it.
5. He comes back to earth and is unharmed.
Conclusion: You're an idiot.
It doesn't get any simpler than that.
Furthermore, Superman's been inside the explosion of the moon and wasn't even knocked out, been inside the explosion of War World and wasn't even knocked out, was inside an exploding Sun Eater which has the power of multiple supernovas and was knocked out but survived (and he's gotten much stronger since then), survived the explosion of another Sun Eater after being weakened by red sun radiation that was equal to 50 supernovae, absorbed the power of the Mageddon Warhead which could destroy half a galaxy (and it was negative sunlight, so it harmed him instead of helping him, since it was the opposite of the energy that powers him), he has flown through the sun's core multiple times (and he only gains power from yellow sunlight, not the heat and pressure, which is far more intense than the power required to destroy a planet), he has been inside the Earth's core and the core of other planets like Almerac and been fine, he has taken blasts from Green Lanterns who can destroy planets easily, he has flown through red suns, that weaken and sap his powers in addition to harming him with their heat and pressure, he has been hit with the Claw of Horus which had the entire mass of the Earth behind it and wasn't even KO'd (he was only pretending to be KO'd), he's been punched across the earth, from the earth to the moon, through the earth and out the other side, and been unharmed, he's taken blasts from Imperiex, who is a universe buster, he fought Darkseid and tore apart a planetoid by just fighting on it, he fought Zod while weakened and under a red sun and they were tearing apart a planet while just fighting on it, he's taken punches from Superboy Prime, who can warp time and reality with his punches and move planets all the way across the universe (which takes way more power than just destroying them), he's survived inside a black hole and escaped, he's escaped the pull of another black hole that opened just beneath his feet, he's held yet another black hole in his hands, he was trapped under an alien device that simulated a black hole's gravity and was only minorly inconvenienced (and this was early in his career from a flashback and he has gotten much stronger since then), he's been hit by antimatter explosions and survived, he's destroyed battle fleets which have been said to be able to wipe out planets, he's flown right through a moon at FTL speeds and split in half and been unharmed, he's heated and cooled a white dwarf star at the earth's core with a whole planet's worth of pressure on his head over and over again to create artificial gravity, etc.
All of these are Post - Crisis and canon, and off the top of my head. There are doubtless at least 10 times more feats I'm forgetting.
However, you're just going to deny or ignore them, because you're blinded by your stupid fanboyism.
Arguing with you is pointless.
