GRAVITATIONAL ORIGIN OF PHANTOM DARK ENERGY AND LATE COSMIC ACCELERATION S.K.Srivastava
Here, dark energy is obtained using dual roles of the Ricci scalar (as a physical field as well as geometry). Dark energy density, obtained in this model, mimics phantom and the derived Friedmann equation contains a term ρde/2λ with ρde being the dark energy density and λ, called as cosmic tension. It is like brane-gravity inspired Friedmann equation, which arises here without using the brane-g...

In this letter, dark energy is obtained using dual roles of the Ricci scalar (as a physical field as well as geometry). Dark energy density, obtained in this model, mimics phantom and the derived Friedmann equation contains a term ρde/2λ with ρde being the dark energy density and λ being the cosmic tension, like brane-gravity inspired Friedmann equation. It is found that acceleration is transie...
متن کاملHolographic dark energy and late cosmic acceleration
It has been persuasively argued that the number of the effective degrees of freedom of a macroscopic system is proportional to its area rather than to its volume. This entails interesting consequences for cosmology. Here we present a model based on this “holographic principle” that accounts for the present stage of accelerated expansion of the Universe and significantly alleviates the coinciden...
متن کاملGravitational energy and cosmic acceleration
Cosmic acceleration is explained quantitatively, as an apparent effect due to gravitational energy differences that arise in the decoupling of bound systems from the global expansion of the universe. “Dark energy” is a misidentification of those aspects of gravitational energy which by virtue of the equivalence principle cannot be localised, namely gradients in the energy due to the expansion o...
متن کاملCosmic Acceleration, Dark Energy, and Fundamental Physics
A web of interlocking observations has established that the expansion of the Universe is speeding up and not slowing, revealing the presence of some form of repulsive gravity. Within the context of general relativity the cause of cosmic acceleration is a highly elastic (p " #!), very smooth form of energy called ‘‘dark energy’’ accounting for about 75% of the Universe. The ‘‘simplest’’ explanat...
