  The big trip is a cosmological process thought to occur in the future by
which the entire universe would be engulfed inside a gigantic wormhole and
might travel through it along space and time. In this paper we discuss
different arguments that have been raised against the viability of that
process, reaching the conclusions that the process can actually occur by
accretion of phantom energy onto the wormholes and that it is stable and might
occur in the global context of a multiverse model. We finally argue that the
big trip does not contradict any holographic bounds on entropy and information.
