A submerged telescope tested relativity from 1.5 miles deep
DFace News
Physicists have deployed a neutrino telescope on the Mediterranean seabed, 1.5 miles below the surface, to probe a fundamental principle of Einstein's theory of relativity. The partially built detector searched for violations of Lorentz invariance, a core symmetry in physics, but found no evidence of cracks. Despite being only half complete, its sensitivity already matches detectors many times larger, demonstrating impressive performance for its scale. The null result tightens the constraints on possible deviations from relativity, showing that even a work-in-progress instrument can contribute meaningfully to foundational physics.
