I already said more than i should about that but i have a new theory about the explosion on Ceti Alpha VI : "BLAME THE SCIENTISTS FROM THE GENESIS PROJECT!"

My own conspiracy theory establish this : in a hurry to show results and without any knowledge of Carol Marcus or his son (probably but not certainly) the cientists test Genesis on Ceti Alpha VI and because of that the planet explode.

After that they made everything that was necessary to hide all evidences of their clumsiness :

- they modified and substitute every cartographic data about the Ceti Alpha system from Starfleet data banks;

- they remove all reports about the location of Khan and his Augments (after all they should be probably dead so why bother to rescue the dead bodies of your only accusatory witnesses ?) and removing the beacon in orbit broadcasting that Hitchhikers maybe Genetically enhanced supermen with delusions of godhood (because they must be all dead right ? We never bother to check that anyway);

- They assigned the most gullible, fresh from Academy bunch of idiots in Starfleet history to help them finding new test sites for their non-doomsday device of doom (and tell them to avoid the Ceti Alpha system ? Why ? That people on Ceti Alpha V should probably be dead by now, it's nothing like they were a bunch of supermen or something, they should be fried freaks at this point).

- And any member of the science crew involved in this "minor set back" was send for mandatory vacation on Nimbus III, the planet of peace for some stress relief.

Be far far away during the events presented in the movie was really lucky and has nothing to do with conspiracy plot convenience despite the fact all of them die on arrival at Nimbus III thanks to suddenly unexpected teletransport malfunction, auxiliary transport crash landing, food poisoning, turbo lifter disastrous lack of maintenance, the eventual warp core breach and resulting explosion in orbit as well explosive atmospheric decompression of all escape pods as such the lack of EVA suits provided with helmets, the following destruction of the original Nimbus III resort when the buildings were hit by the debris and hull of the U.S.S. Titanic.

Starfleet regret the lost of a fine ship just two days before decommission.

If at least there was an real crew to take care of all those things that goes wrong that day instead of a (literal) skeleton crew and automated systems maybe the death of all 253 cientists involved(most of them with no links to the Genesis Project) could be avoided, too bad all their logs and research data was lost and never recovered despite the fact every starship has audio and video recorders through the whole ship secretly broadcasting everything that happens inside 24/7 back to Starfleet headquarters.

After all any theory about federation scientists blowing up whole planets it's completely absurd, isn't Mr. Sloan ?

_"Well, that's certainly a nice synopsis for something like : Star Trek Final Destination The Wrath of  Garak" ! (sinister chuckles) (mental note, made this guy Captain of some doomed vessel and send him where no one has gone before immediately - anywhere deep into Dominion or Borg territory and made the ship explode like in an misfortune "accident" just for sure ) (even more sinister chuckles)
