I don't feel knowledgeable enough to say things about the safety
of the experiments to be done at the Large Hadron Collider.

However, I have a thought experiment about risk-assessment
relating to high-energy physics. Suppose experimental h.e.p.
were to continue growing and evolving over up to the next
million years. Imagine bigger and bigger colliders.
The unknown remains unknown until it becomes known,
roughly speaking. Sometimes evidence accumulates over
decades, and other times a decisive experiment makes
a big difference to what is known in a short period
of time.

What are the chances that up to the end of the next million
years, there will be a (non-military, non-applied)
high-energy physics experiment malfunction that will be
the direct cause of 1 billion or more human deaths?

If it's likely, how do we know or how would we know?
If it's unlikely, how do we know or how would we know?

we'll be killed tomorow. probability 10%.
