We urge the reader to consider the evidence below and its implications for great danger in operating LHC's heavy ion collision. For evidence of further contradictions from CERN's own physicists with statements of CERN's Safety Report and an outline of available doubts by physicists concerning the remaining assurance arguments, please see the report.

What are dangerous strangelet attributes? - As shown here - i) negative electric charge and ii) stability:

How CERN’s Documents Contradict its own Safety Assurances: Plans for




Detection at the LHC


Heavy Ion Alert is an international group of critics concerned about the insufficiency of existing safety arguments regarding Large Hadron Collider's heavy ion  collisions (between lead nuclei) and the unsatisfactory nature of the associated regulatory proces

As shown below, CASTOR is the LHC's detector primarily for strangelets:
According to both CASTOR theory and another CERN theory, strangelets could satisfy dangerous attribute (i) of negative
Again according to these theories, LHC strangelets could also satisfy dangerous attribute (ii) of stability:
