Deep-Sea Telescope Tests Einstein’s Limits in Mediterranean Neutrino Hunt

Physicists have deployed a telescope nearly 1.5 miles beneath the Mediterranean Sea to probe one of modern science’s most durable ideas: Einstein’s theory of relativity. The underwater detector is designed to capture elusive neutrinos and check whether they obey Lorentz invariance, a cornerstone of relativity that has survived every major experimental challenge so far.
