  The recent development of water-based liquid scintillator and the concurrent
development of high-efficiency and high-precision-timing light sensors has
opened up the possibility for a new kind of large-scale detector capable of a
very broad program of physics. The program would span topics in nuclear,
high-energy, and astrophysics, ranging from a next-generation neutrinoless
double beta decay search capable of covering the inverted hierarchy region of
phase space, to supernova neutrino detection, nucleon decay searches, and
measurement of the neutrino mass hierarchy and CP violating phase. This paper
describes the technical breakthroughs that led to this possibility, and the
broad physics program thus enabled. This paper is a summary of a talk presented
at the NuPhys 2014 conference in London.
