  A physical mechanism that produces three energy components is proposed as the
common origin of dark energy and dark matter. The first two have equations of
state W ~ 0 and act like dark matter, while the last has W ~ -1 at low
redshifts making it a candidate for dark energy. These are used to model the
supernovae Union2 data resulting in a curve fitting identical to the LAMBDACDM
model. This model opens new avenues for Cosmology research and implies a
re-interpretation of the dark components as a scalar field stored in the metric
of spacetime.
