Is the Large Hadron Collider dangerous?

Answer 1

I assume you are asking about the myth that somehow the LHC will create a singularity (black hole) and ,for lack of a better word, absorb the solar system. In which case the answer is no the LHC is perfectly safe,

However there are always risks with any high energy particle experiments, radiation and high magnetic fields are of course a by product of the project, though there is no need to worry about any of those phenomena as they are safely contained and shielded
