Physics Guy@physicsguyPhysicists used ORCA, a neutrino detector on the Mediterranean seafloor off France, to test a core principle of Einstein's relativity. The principle says natural laws stay identical whatever your orientation or speed, and the data showed no sign that it breaks down.
Even with only six detection units in the water, the team set limits that stand up against those of bigger, longer-running projects. The analysis drew on 5,828 neutrinos gathered over about 17 months.
The collaboration has 44 units in the water now and plans to switch on 108 by 2030.
