*Abstract:*

*//*

/The history of the early universe offers several key puzzles, which are 
presently addressed by
particle physics. They include the the matter/antimatter asymmetry, the 
left-handedness of the
Universe and primordial nucleosynthesis. All these questions are 
directly related to discrete
symmetries and their violation.  When using accelerators, the 
sensitivity for their exploration
is directly connected to the maximum beam energy.  Neutrons offer a 
complementary approach and the sensitivity is only given by the 
experimental precision achievable. In addition the search
for new phenomena becomes less model dependent.  Since about a decade, 
particle physics with neutrons is also used to address gravity and 
gravity-like forces with unprecedented precision.  This maybe one of the 
very few ways, how to address issues relevant to the very early 
Universe.  The talk will give an overview on the physics and the 
experimental approaches and will also highlight some of the challenges 
which are met.///
