Some notes on the Big Trip

TL;DR

This paper explores the theoretical possibility of the universe undergoing a 'big trip' through wormholes driven by phantom energy, arguing its stability and compatibility with holographic principles within a multiverse context.

Contribution

It demonstrates that the big trip can occur via phantom energy accretion, establishing its stability and consistency with holographic bounds, expanding understanding of cosmic evolution scenarios.

Findings

The big trip can occur through phantom energy accretion.

The process is stable within a multiverse framework.

It does not violate holographic entropy bounds.

Abstract

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.
