The LHC will do nothing but expand our physics understanding.
It is going to achieve a very high energy density.
However, the total energy in any of its collider events is very small.
Not enough total energy to do anything of significance.
A comparitivly small amount of energy compressed by the collision to a high density.
It would take a lot more energy than the collider is capable of producing to do anything of significant scale.
It is a single subatomic collider event.
All it is capable of doing is expanding our science.
There were some who feared that the first atomic bomb explosion would start a chain reaction that would destroy the earth.
That was a lot more energy than a single subatomic collider event.
And we are still here.
Whatever works, use it.
A good idea stands on its own value independent of authorship.
If it stands or falls on the credibility of the author, maybe it isn't such a good idea.
