Since humans first evolved (yep the evil word) we have been seeing the potential of things around us. Stone tools, use of animals, planting crops, developing the wheel, building shelter, making and controlling fire........and it just continues today.
Its part of our make-up to keep wanting to question and discover. Part of that is experimentation. We call it science...and without it we would never have come from the primitive lifestyle of the early humans.
Colliding two protons together an watching the results is a little like planning to send humans to the moon. The spin offs are unknown....but whatever happens, it will change our lives for the better into the future.
Black Hole? bahhh humbug
