trailParticle collisions at the LHC pose no danger to Earth.
Hazard-by-hazard exclusion· for
TeV-scale black holes produced at the LHC pose no significant risk.
Microscopic black holes evaporate almost instantaneously via Hawking radiation.
↑
Cosmic ray collisions with Earth's atmosphere reach energies exceeding LHC collision energies.
◌
◌
Stable neutral black holes produced by cosmic rays would pass through Earth without being gravitationally captured

+7
Dangerous strangelet production at the LHC is excluded by theory and RHIC observations.
atomic
A high-energy particle collision could trigger the universe's vacuum to decay into a more stable state.
The Standard Model electroweak vacuum is metastable rather than absolutely stable.
✓
?
↑
The predicted lifetime of the metastable electroweak vacuum vastly exceeds the current age of the universe.
Cosmic-ray precedent· for
Cosmic rays with energies exceeding LHC collision energies have struck Earth for billions of years without causing catastrophe.
atomic
Survival of white dwarfs and neutron stars constrains TeV-scale black hole accretion rates.
