What seemed to hold the promise of a revolution in physics has fizzled out. Disappeared into oblivion. Is there really nothing more than the Higgs for the LHC to discover? Will the experiment just wander in an energy desert for the rest of its life? It is the most feared scenario physicists could have thought of before switching on the machine at CERN: a true nightmare. What now? Someone is probably hoping this nightmare will let us save money on curiosities that only experts care about and are of no public good for the majority. So wrong!
I have friends who work in theoretical particle physics: they are passionate, capable scientists and I’ve always wished the results found at LHC would help them land the permanent position they deserve to keep doing what they’re best at. Now that everyone in the field is back to square one, my friends are among the best positioned to start a new conversation with Nature through the screen of a blackboard: they are still professionally young enough to be as audaciously bold as the situation requires. So far, in fact, the community of theoreticians has mostly played by decade-old rules: no wonder we’re stuck. It is then a great opportunity to make tabula rasa and be daring. I’m confident the revolutionary men and women that’ll get us out of this morass are already born: hopefully they’re already at work and they are collaborating with each other to enjoy the benefits of complementarity.
However, things could turn out bad: the work toward a new description of Nature might take more time than my friends have to secure a job. As numerous as they can be, and even if they may come from your own country, I don’t think the destiny looming on them will move you. However, in such a case, a catastrophe will be pending above us all.
While it may look like CERN hunts for Pokemon-like entities in reality it does much more: it creates the basis for our future wellbeing. The past week, together with the sad announcement of the aborted physics revolution, CERN celebrated the 25th anniversary of the World Wide Web. It was invented there and you use it to read this piece or the news, to book the flight to go on holidays, to buy shoes and do many more things that are now given for granted in our everyday life.
CERN also has a medical research unit, where particle physics know-how from theory and experiments is put to service for health applications such as treating cancers. Moreover, for its computing needs CERN has been instrumental in the development of Grid computing, which
“… offers a way to solve Grand Challenge problems such as protein folding, financial modeling, earthquake simulation, and climate/weather modeling. Grids offer a way of using the information technology resources optimally inside an organization. They also provide a means for offering information technology as a utility for commercial and noncommercial clients, with those clients paying only for what they use, as with electricity or water.”
There is much more that CERN does for us all but I’m confident the overview I’ve given you can already let you share my concern that if we stop doing research in particle physics we stop creating needs that only this type of research can create, while their satisfaction provides the most fertile conditions for our future wellbeing and prosperity.
Before concluding, it is worth mentioning that the non-discovery of a new particle does not mean CERN should close shop just yet. In fact, knowing that the particle is not there is already a precious piece of information: we could not know beforehand, so disposing of a new piece of (non-)evidence is very useful, though painful.
At the same conference where the sad non-discovery announcement has been made a flood of other new results has been shared with the public by CERN. They still have some twenty years of activity in front of them to let the LHC machine continue its tremendously accurate and reliable work. This persistence is needed to allow new rare phenomena to show up in a significant way. Therefore, we can be “disappointed but not discouraged” as a physicist says at the end of a BBC Horizon documentary that just aired.
Last but not least, a note is in order about the title: Meyrin Street is CERN’s address for the public.
