  We recently formulated a model of the universe based on an underlying
W3-symmetry. It allows the creation of the universe from nothing and the
creation of baby universes and wormholes for spacetimes of dimension 2, 3, 4, 6
and 10. Here we show that the classical large time and large space limit of
these universes is one of exponential fast expansion without the need of a
cosmological constant. Under a number of simplifying assumptions our model
predicts that w=-1.2 in the case of four-dimensional spacetime. The possibility
of obtaining a w-value less than -1 is linked to the ability of our model to
create baby universes and wormholes.
