Taking the complex nature of quantum mechanics which we observe today
as a low energy effect of a broken quaternionic theory we explore the
possibility that dark matter arises as a consequence of this underlyin
g quatemionic structure to our universe, We introduce a low energy, ef
fective, Lagrangian which incorporates the remnants of a local quatemi
onic algebra, investigate the stellar production of the resultant exot
ic bosons and explore the possible low energy consequences of our remn
ant extended Hilbert space. (C) 1997 Elsevier Science B.V.
