The LHC: the safety argument has evidence

Starting to circulate a beam and producing the later collision programme are different milestones. The earlier entry merged them. CERN’s safety statement and the underlying assessment give a way to evaluate the risk argument rather than count the commissioning day as a generic missed apocalypse.

Natural cosmic rays provide evidence relevant to the proposed catastrophic mechanisms. Read the assessment for the physical reasoning and its scope. The ledger does not add unsourced claims about lawsuits or treat all concerns as equivalent simply because they share a date.
