2 00 6 Non - violation of Energy Conditions in the future accelerated universe due to quantum effects
نویسنده
چکیده
Here, an accelerated phantom model for the late universe is explored, which is free from future singularity. It is interesting to see that this model exhibits strong curvature for all time in future, unlike models with 'sudden future singularity' showing high curvature near singularity time only. So, quantum gravity effects grow dominant as time increses in late universe too. More importantly, it is demonstrated that quantum corrections to FRW equations lead to non-violation of 'cosmic energy conditions' of general relativity, which are violated for accelerating universe without these corrections.

Here, an accelerated phantom model for the late universe is explored, which is free from future singularity. It is interesting to see that this model exhibits strong curvature for all time in future, unlike models with 'big-rip singularity' showing high curvature near singularity time only. So, quantum gravity effects grow dominant as time increases in late universe too. More importantly, it is...

The SNe type Ia data admit that the Universe today may be dominated by some exotic matter with negative pressure violating all energy conditions. Such exotic matter is called phantom matter due to the anomalies connected with violation of the energy conditions. If a phantom matter dominates the matter content of the universe, it can develop a singularity in a finite future proper time. Here we ...

Eternal inflation, black holes, and the future of civilizations. Abstract We discuss the large-scale structure of the universe in inflationary cosmology and the implications that it may have for the long-term future of civilizations. Although each civilization is doomed to perish, it may be possible to transmit its accumulated knowledge to future civilizations. We consider several scenarios of ...

Here, creation of the universe is obtained out of gravity only. The dy-namical universe begins with two basic ingredients (i)vacuum energy, also called dark energy (as vacuum energy is not observed) and (ii) background radiation. These two are obtained through one-loop renormalization of ric-cion. In the proposed cosmology, it is found that not only current universe expands with acceleration, b...
