One ring to rule them all?
CERN has published, in four volumes, its ideas for a
£20bn successor to the Large Hadron Collider (LHC), given the working name of
Future Circular Collider. The circular tunnel would have a circumference of
about 100 kilometres (62 miles), almost four times longer than the current LHC.
Undoubtedly it would be a tool for progressing particle physics and our knowledge of matter and dark matter. However
will politicians and those in other scientific areas think it precious?
