Deep-sea neutrino telescope tests Einstein's relativity, finds no cracks
ORCA detector, sunk 1.5 miles beneath the Mediterranean, sets competitive limits on Lorentz invariance violation
A neutrino telescope sunk more than a mile beneath the Mediterranean off the coast of France has tested a core principle of Einstein's relativity, Lorentz invariance, and found no evidence of violation, according to a study published Wednesday in the Journal of Cosmology and Astroparticle Physics.
