  Recently Pedro F. Gonzalez-Diaz had shown that phantom energy can results in
achronal cosmic future where the wormholes become infinite before the
occurrence of the big rip singularity. After that, while the phantom energy
continues its accretion, any wormhole becomes the Einstein-Rosen bridge. Pedro
F. Gonzalez-Diaz has suggested that such objects can be used by an advanced
civilization as the means of escape from the big rip. Using the Bekenstein
Bound we'll show that it is impossible due to the very strong upper bound laid
on the total amount of information which can be sent through this bridge.
