The road to a bigger collider?

News were making the rounds on Friday that the CERN council unanimously decided that in their research strategy they’re placing (most but not all) their bets on the Future Circular Collider (FCC), the 100km circumference proton-proton collider that would reach energies of about 100TeV. This is discussed in Nature and on Peter Woit’s blog.

A critical essay by Sabine Hossenfelder appeared in SciAm where she voiced her previous concerns that in contrast to the LHC there is no guarantee that physicists will find anything and that it is therefore hard to make a scientific case for such a huge amount of money.

Update: For anyone who speaks French or is able to use online translating tools, there is also an article in Le Monde about the topic by Adam Falkowski, author of Résonaances.
