A MODIFIED FRW METRIC TO EXPLAIN THE COSMOLOGICAL CONSTANT

One of the most outstanding problems of the standard model of cosmology today is the problem of cosmological constant/darkenergy. It corresponds to about 73% of the energy content of the universe gone missing. I here by postulate a modified FRW metric for our universe, which animates a universe spinning very slowly with an angular frequency that is equal to the Hubble's constant. It is shown by a simple argument that in such a universe there will be an overlooked rotational energy whose average value is identically equal to the matter-energy content of this universe as observed by acoordinate observer. The corresponding Friedmann equation is derived, where by the overlooked rotational energy naturally becomes the cosmological constant/dark energy term without artificially/mysteriously adding any such term,as is commonly done. The proposed model also produces Hubble's law naturally.
