Now before you explode and say 'total gobblydegook!', please understand that I am only a layman and that the argument is not actually mine. I do not even know if it makes any sense. That is why I ask the people here.

I would like to see someone debunk that particular objection, because any time I see anyone 'debate' these things it goes like this:

'The LHC could destroy the world!'

'No it couldn't, interactions like that happen all the time from cosmic rays and nothing has gone wrong so far, has it.'

'But the cases aren't the same, because LHC products can be expected to remain in the vicinity of the Earth, unlike those produced by cosmic rays!'

[silence]

You can see why it is frustrating for me. I cannot follow physics, but I can follow an argument, and there is usually something missing in this one, i.e. the step that says 'Bollocks, because ...'

So can someone here provide that? Thanks.
