> But there is a "group of people who have been doing high energy physics that want to keep doing high energy physics". Apparently it needs to be said because people act like they don't know it: those are the only people interested in answering questions about the fundamental particles! Diverging interests is the fundamental reason people separate into different fields. > they might not even know about the other approaches You can easily find the lists of seminars given at CERN and other places: they do know about other fields. In fact people from HEP move to other fields, and folks from other fields move into HEP. > Try some of the 10 million dollar machines rather than only the 100 billion dollar machines. They are being built though! In fact there are 2 billion experiments being built. The argument here is something else: that High energy physics should just stop building big machines at all, and instead magically solve the problem that small machines were built and fully exploited many many decades ago. The proposed FCC cost is 30 billion.
