Cern has built a 7 mile and $9 billion machine to recreate the conditions after the Big Bang.
Word on the street is that there is a chance that it could cause a black hole or black holes that would destroy our universe.

Info from cern's website:
The Large Hadron Collider (LHC) is a gigantic scientific instrument near Geneva, where it spans the border between Switzerland and France about 100 m underground. It is a particle accelerator used by physicists to study the smallest known particles – the fundamental building blocks of all things. It will revolutionise our understanding, from the minuscule world deep within atoms to the vastness of the Universe.

Two beams of subatomic particles called 'hadrons' – either protons or lead ions – will travel in opposite directions inside the circular accelerator, gaining energy with every lap. Physicists will use the LHC to recreate the conditions just after the Big Bang, by colliding the two beams head-on at very high energy. Teams of physicists from around the world will analyse the particles created in the collisions using special detectors in a number of experiments dedicated to the LHC.

It is said that the pressure inside of one particle weighs as much as the whole universe. So how could we keep something like this contained?

Info from lhcdefence.org
Black holes are usually conceived as being the remnant of a massive star that has used up its nuclear fuel, and crushed itself under its own weight. Its gravitational pull at its surface then becomes so great nothing can escape, not even light. It becomes literally a “hole” in the fabric of space-time, and anything that enters can never escape.

There is a lot more to the story, I haven't even swept the tip of the iceberg. I listed websites for you to get the full idea.
What I want to know:
Is it worth the risk of destroying our universe to gain this knowledge even if the risk is small?
I have heard that there is a .01% chance of a black hole danger, and I have also heard that there is a 16% chance. Does the percentage make a difference as far as taking the risk?
What great knowledge would we gain and what would we use it for? This will take some research.
I would love to hear your thoughts.
