YouTube - The Large Hadron Collider: The End Of The Universe?
Hope nobody else has posted this yet, but its a video that explains in a pretty entertaining way about the hadron collider, that most people could understand.
As a side note, it might not be such a big deal if we did manage to instantaneously destroy ourselves.
In my opinion, if its worth anything, humans are very self-important, and have mostly decided without a complete frame of reference, that they are either the purpose of the universe, or the most sophisticated and only worthwhile result of the universe.
A sudden end to the human experience would result in a lot of happiness no longer being possible, but it would also result in the end of a lot of suffering.
Considering the magnitude of what the doom sayers are saying might happen, it would be pretty much a neutral experience for us. Humans' comprehension of the universe would just cease, and the universe would go on doing whatever the hell it's doing, without us.
