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 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...
متن کامل1 J ul 2 00 9 Wormholes supported by Scalar Fields with Negative Kinetic Energy
We provide a new model of higher dimensional wormholes supported by phantom energy derived from a scalar field with negative kinetic term. We have shown that the Averaged Null Energy Condition ( ANEC ) violating phantom energy can be reduced as desired. We have also noticed that dimension of the spacetime plays a crucial role for measuring the ANEC violating matter needed.
