The Large Hadron Collider might well be the last machine of its kind that ever gets built. But the fact that it was built is extremely heartening. This is a machine so large it takes hours to jog around. It cost billions of euros and took many years to build. That governments were willing to pay for it, with no idea what it might or might not find, speaks volumes about the price society is willing to pay to understand more about our place in the universe.
