Repeat After Me: Particle Physics Is Not All of Physics

[T]hat [number] almost certainly overestimates the number of people working directly on a Theory of Everything. The fact is, the physicists whose work is genuinely in crisis as a result of recent developments (or, more accurately, the lack thereof) are a tiny minority of professional physicists. They’re vastly overrepresented in the media, in large part because wildly speculative stuff about multiple universes is sexy and provides lots of opportunities for stoner-friendly CGI, but if they all got sucked into a black hole tomorrow (thus settling the “firewall” debate for good and all), physics as a whole would continue on with barely a hiccup.
