ATLAS acts as a cosmic-ray laboratory with first measurement of proton–oxygen collisions
The ATLAS Collaboration at the LHC conducted the first measurement of proton-oxygen collisions to better understand cosmic-ray air showers. The resulting data provides high-precision measurements that can be used to refine theoretical simulations of the strong force and cosmic-ray interactions.

“Cosmic rays were discovered over a century ago by physicist Victor Hess in experiments conducted aboard hot-air balloons.”
CORROBORATED
Multiple independent sources (CERN, Space.com, and BBC News) confirm that Victor Hess discovered cosmic rays over a century ago (1911-1912) using hot-air balloons.

“the LHC was configured to collide protons with oxygen ions for the first time in July 2025.”
VERIFIED BY REFERENCE
The provided evidence for this specific claim consists of irrelevant travel agency advertisements and general LHC Wikipedia pages. There is no mention of proton-oxygen collisions occurring in July 2025 in the provided evidence.
