CERN’s LHC: No Doomsday Black Hole Threat
Could CERN's Large Hadron Collider create a doomsday black hole? While theoretically possible under certain speculative physics, the scientific consensus and evidence suggest the risks are vanishingly small, with microscopic black holes likely evaporating instantly or having negligible gravitational impact.

LIGO Detects Strongest Evidence Yet for Hawking’s Area Theorem
LIGO's latest observations of a black hole merger, GW250114, provide the strongest evidence yet for Stephen Hawking's 1971 area theorem. The data confirms that the surface area of the resulting black hole was greater than the sum of the areas of the merging black holes, validating a key prediction about these cosmic enigmas.
