IPhantom dark energy and its cosmological consequences. |
Abstract _ |
I will discuss phantom ($p<-\varrho$) dark energy which is an observational option for the current acceleration of the universe. Phantom forces the universe to expand even faster then the cosmological constant and brings it to the final disruption of the whole matter in a large size and density state - a Big-Rip. I will review possible classical and quantum cosmologies with phantom dark energy and relate them to superstring and M-theory cosmologies (scale factor and phantom dualities). Besides, I will also discuss other more exotic scenarios of the future evolution of the universe. |
