At first, the community despaired. “You could feel the pessimism,” said Isabel Garcia Garcia, a particle theorist at the Kavli Institute for Theoretical Physics at the University of California, Santa Barbara, who was a graduate student at the time. Not only had the $10 billion proton smasher failed to answer a 40-year-old question, but the very beliefs and strategies that had long guided particle physics could no longer be trusted. People wondered more loudly than before whether the universe is simply unnatural, the product of fine-tuned mathematical cancellations. Perhaps there’s a multiverse of universes, all with randomly dialed Higgs masses and other parameters, and we find ourselves here only because our universe’s peculiar properties foster the formation of atoms, stars and planets and therefore life. This “anthropic argument,” though possibly right, is frustratingly untestable. |

A candidate for the fundamental theory of gravity and everything else, string theory holds that all particles are, close up, little vibrating strings. Standard Model particles like photons and electrons are low-energy vibration modes of the fundamental string. But the string can wiggle more energetically as well, giving rise to an infinite spectrum of string states with ever-higher energies. The hierarchy problem, in this context, asks why corrections from these string states don’t inflate the Higgs, if there’s nothing like supersymmetry to protect it. |

An A.I. system using real-life data could probably manage it. |
