DESCRIPTION:Spontaneous localization (SL) is an alternative to standard qu
 antum theory in which quantum state reduction is treated as a random physi
 cal process which is incorporated into the Schroedinger equation in an obs
 erver-independent way. We give a brief introduction to SL and a review of 
 some proposed relativistic extensions. Based on these relativistic extensi
 ons we argue that for a single particle\, non-relativistic SL should remai
 n valid in the rest frame. This implies that relativistic calculations can
  be performed by transforming non relativistic results from the particle r
 est frame to the frame of an observer. We demonstrate this by considering 
 a relativistic stream of non-interacting particles of cosmological origin 
 and showing how their energy distribution evolves as a result of SL as the
 y traverse the Universe. We present a solution and discuss the potential f
 or astrophysical observations.\n
