Phenomenology of a realistic accelerating universe using only planck-scale physics



Phenomenology of a realistic accelerating universe using only planck-scale physics



Physical Review Letters 84(10): 2076-2079



Modern data are showing increasing evidence that the Universe is accelerating. So far, all attempts to account for the acceleration have required some fundamental dimensionless quantities to be extremely small. We show how a class of scalar field models (which may emerge naturally from superstring theory) can account for acceleration which starts in the present epoch with all the potential parameters O(1) in Planck units.
