CERN Large Hadron Collider Doomsday Fears

Record	OBS-0496
Category	Unsorted/Other
Status	DEBUNKED
Summary	Proponents claim that the Large Hadron Collider (LHC) at CERN could create black holes or other catastrophic phenomena that would destroy Earth. These fears led to lawsuits and widespread public concern before the LHC's activation. Scientists and experts have consistently dismissed these scenarios as physically impossible or extremely improbable.
Origin	The fears emerged in the early 2000s, intensifying before the LHC's first beam in September 2008, with lawsuits filed in the US and Europe.
Claimed	The LHC could create a black hole that would swallow the Earth. The LHC could produce 'strangelets' that convert ordinary matter, or other dangerous particles. The LHC might trigger a vacuum bubble that would destroy the universe. The LHC is dangerous and should be stopped.
Evidence / consensus	The scientific consensus, including safety assessments by CERN and independent physicists, confirms that cosmic rays with far higher energies have been colliding with Earth and other celestial bodies for billions of years without causing harm. Any microscopic black holes produced would evaporate instantly via Hawking radiation, and the energies involved are far too low to create dangerous strangelets or vacuum bubbles.

> OBSERVER NOTE:
A classic case of public misunderstanding of high-energy physics. The lawsuits were dismissed, and the LHC has operated safely for over a decade. The fear persists in some corners despite the lack of any evidence.
