On the cosmological constant problem and its relation to the extrinsic shape of the universe

Abstract : Within the conventional big-bang cosmological model, it is very difficult to understand why the cosmological constant is so small. In this talk, first, I will discuss a new classical unified field theory (like Kaluza-Klein theories), where Yang-Mills fields have a geometrical origin, arising from twisting vector fields of the non-compact bulk space. Applying this formalism to cosmology, I derive the generalized Friedmann equations. It is also shown that the cosmological constant could actually be the manifestation of the extrinsic shape of the 4D spacetime in the 11D bulk space. The predictions of this model are in good agreement with observations.
