五十年后，再看FCC

- The article refers to the **Future Circular Collider (FCC)**, not the U.S. Federal Communications Commission. FCC is CERN's proposed next-generation particle accelerator, planned to succeed the Large Hadron Collider (LHC). - The FCC project envisions a ~91 km ring (vs. the LHC's 27 km) near Geneva, starting with an electron-positron collider (FCC-ee) as a "Higgs factory," followed later by a hadron collider (FCC-hh) reaching ~100 TeV. - CERN approved the FCC feasibility study in 2021; a final decision on construction is expected around 2027–2028, with operations possibly beginning in the 2040s. Estimated cost is in the tens of billions of euros. - The article is published in *CERN Courier*, the lab's official magazine, and likely reflects the pro-FCC institutional perspective. Critics question the cost, the timeline, and whether the scientific payoff justifies building such a machine while other global projects (e.g., China's CEPC, Japan's ILC) vie for funding and talent.
