Scientists Test Physics Under the Sea

In this lesson: Identify the instrument and state the result without overstating it.

Read the story

Scientists used an underwater detector called ORCA to study tiny particles called neutrinos. The detector is in the Mediterranean Sea.

They looked for changes that could challenge a basic rule of physics. They found no sign of those changes.

The result helps limit how large some possible effects could be. It does not prove that such effects can never happen. The research received new journal coverage on November 4.
