They are interested in learning about the basic building blocks of the universe and the ways in which they can interact. The way they go about this is to smash particles together, at high energies, and then see what happens. It’s a crude way of studying the physical world, but it’s remarkably effective. However, some people believe that the high energies involved in such experiments could initiate some sort of global disaster. If particle physics experiments can indeed produce doomsday, and if an intelligent species’ natural curiosity about the universe leads them inexorably to build such
