I like to think of it from this point of view: If they are ultimately unable to contain any black holes created by this thing, It should mean that “they” will be the first to be sucked into it.
I don’t believe this one is about creating black holes. It’s excellerates particles and crashes them to do scientific research into the minutest particles of the universe. If I remember correct, we donated a hundred million or so for this project.
Let’s just hope it swallows a few things and disappears. I’d hate to be swallowed by a manmade black hole, while standing on the Earth.
