A modified Friedmann equation

Understand

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.
