There is a very good article, the DOOMSDAY FEARS SPARK LAWSUIT (Cosmic Log) that covers the recent efforts to stop the Large Hadron particle super collider from going online, due to fears that it might cause a doomsday scenario.
Representatives at Fermilab in Illinois and at Europe’s CERN laboratory, two of the defendants in the case, say there’s no chance that the Large Hadron Collider would cause such cosmic catastrophes.The builders of the world’s biggest particle collider are being sued in federal court over fears that the experiment might create globe-gobbling black holes or never-before-seen strains of matter that would destroy the planet.
And more incredible is:
The current lawsuit could well be decided not by scientific arguments but rather by narrower regulatory issues.
Regulatory issues? That’s stupid and illogical. What are the chances of getting the Earth destroyed due to anti-matter annihilating the Earth? I’m no physicist, but I’ll bet that it’s next to zero. We just don’t know how to generate such tremendous power for long-enough time to annihilate Earth.
Don’t stop scientific progress, there is so much to learn about our Universe.

This experiment is sick and those that think it a joke are sick. The scientists are terrorists in threatening mass destruction of every man, woman, child and organism of this beautiful planet.
They have no right to veto my existence, the lives of my children, life on earth in all its wonderous beauty and complexity. They have no right to threaten the people of Earth with mega death.
The experiment has to be stopped at all costs. No data or knowledge is worth this kind of risk. Science has reached its limitation. People were quite happy in the past with simple pleasures. No one needs this science or data. we have too much already. Humans need to return to simple and sustainable living and not be threatened by a minority of freaks with over sized brains and no appreciation of Nature and everyday things like mountains, birds, insects, flowers or the sunrise.
I totally disagree… these guys are no terrorists. And this is about understanding and appreciating Nature and its evolution and its beauty. The universe is much more than planet Earth alone…

It is not worth risking the entire universe just to discover how the universe came to be. What would this gain? Anyway, it would be more special to not know how the big bang happened in the first place.
There is no risk.
Yes, I want to know how the big bang happened in the first place.
