WHAT *SHOULD* WE BE WORRIED ABOUT?

[ Mon. Jan. 14. 2013 ]

The Edge web-site annual question feature is out today, with this year’s question What *Should* We Be Worried About?. I wrote something about the “Nightmare Scenario” that HEP is facing if the LHC finds a Standard Model Higgs and nothing else. ... Others addressed the same issue, with Lisa Randall writing: "In my specific field of particle physics, everyone is worried. I don’t say that lightly. I’ve been to two conferences within the last week where the future was a major topic of discussion and I’m at another one where it’s on the agenda." ... Amanda Gefter sees no reason to worry. Particle theorists will just move to making progress without experiment, through studying paradoxes of the current theory, with her final example for optimism the recent debate over the “firewall paradox”. ... Carlo Rovelli’s contribution explains one problem with this: humans are very good at convincing themselves they have found some wonderful explanation of something (e.g. some resolution of a paradox, like the supposed SUSY solution to the hierarchy problem), when reality actually involves something quite a bit more subtle and unexpected . . .
