Abstract

We propose a set of equations as a simple model for non singular evolutions of a 10+110 + 1 dimensional M theory universe. Our model uses ideas from Loop Quantum Cosmology and offers a solution to the important problem of singularity resolutions. We solve the equations numerically and find that an M theory universe in this model evolves non singularly and with a bounce : going back in time, its density reaches a maximum and decreases thereafter whereas its physical size reaches a non vanishing minimum and increases thereafter. Taking the constituents of the universe to be the most entropic ones (which are four sets of intersecting M branes) leads to an effectively 3+13 + 1 dimensional spacetime as the M theory universe expands, both in the infinite past and future.
