Sabine Hossenfelder thinks a bigger collider would be a poor investment
CERN is dreaming of a new and larger particle collider, called Future Circular Collider (FCC). The cost would be in the low 10s of billions (dollars or Euros, makes little difference).
Hossenfelder concludes:
... investment-wise, it would make more sense to put particle physics on a pause and reconsider it in, say, 20 years to see whether the situation has changed, either because new technologies have become available or because more concrete predictions for new physics have been made.
At current, other large-scale experiments would more reliably offer new insights into the foundations of ...
