{title2=GRWm}
A version of the <GRW model> in which matter is the ordinary-space density $m(x,t)=\sum_i m_i\int dq\,\delta^{(3)}(x-q_i)|\Psi(q,t)|^2$. This density is proposed as physical matter, rather than ignorance over hidden point positions. A dominant localized density supplies approximate object locations.
