Phantom energy traversable wormholes
It has been suggested that a possible candidate for the present accelerated expansion of the Universe is “phantom energy”. The latter possesses an equation of state of the form ω ≡ p/ρ < −1, consequently violating the null energy condition. As this is the fundamental ingredient to sustain traversable wormholes, this cosmic fluid presents us with a natural scenario for the existence of these exo...
متن کاملWormholes supported by phantom-like modified Chaplygin gas
We have examined the possible construction of a stationary, spherically symmetric and spatially inhomogeneous wormhole spacetime supported by the phantom energy. The later is supposed to be represented by the modified Chaplygin gas equation of state. The solutions so obtained satisfy the flare out and the asymptotic flatness conditions. It is also shown that the averaged null energy condition h...

متن کاملCosmological Perturbations in Phantom Dark Energy Models
The ΛCDM paradigm, characterised by a constant equation of state w = −1 for dark energy, is the model that better fits observations. However, the same observations strongly support the possibility of a dark energy content where the corresponding equation of state is close to but slightly smaller than −1. In this regard, we focus on three different models where the dark energy content is describ...
متن کاملA theoretical construction of wormhole supported by Phantom Energy
A new solution has been presented for the spherically symmetric space time describing wormholes with Phantom Energy. The model suggests that the existence of wormhole is supported by arbitrarily small quantity of Phantom Energy. Wormholes are geometrical structures connecting two distinct space times. It is very interesting object in Modern science as because if traversable wormhole exists , th...
