CERN and the LH collider

Am I the only one who is slightly concerned about the goings on at CERN?  We are allowing scientists with seemingly little or no oversight from democratic corners to mess with stuff on a subatomic level and recreate conditioins that were around just a few seconds after the so called big bang.

Now, from what I've read, things were pretty unstable and violent during these moments, so why risk opening oursselves up to possible malevolent forces that have since been bound and stabilized?  Life is obviously evolving AWAY from those first few seconds, so perhaps there is something we need not, or are not supposed to go back to for the sake of vain knowledge.

Look at the space program and all the resulting space junk and even casualties and deaths that have resulted from it.  How much foresight now can scientists use when opening up such new vistas?

Finally, when have men, once they have gained knowledge, not used said knowledge to the benefit of one's own ends?  It's human nature, isn't it?  'Knowledge is Power', is it not, and apparently we are about to open ourselves up to a whole new, I guess Brave New world of knowledge and power that is going to reside in the hands of a few international scientists.

Does this sound all good to you?
