But further study of this enigmatic element revealed something different.

The most significant advance is the observation that neutrinos can oscillate.

They can oscillate between these so-called different flavors: the electron, the muon, and the tau.

And because we observe this oscillation phenomena, we know that neutrinos have mass, which was not obvious.

And the fact that they have mass opens up all kinds of possibilities about using neutrinos to study other aspects of physics.

And both are designed to search for sterile neutrinos in different ways.

The PROSPECT experiment ran in the year two thousand eighteen at the high flux isotope reactor at the Oak Ridge National Laboratory.

We were very fortunate to be able to work at that unique facility.
