The Destiny of Universes After the Big Trip

TL;DR

This paper uses quantum cosmology to analyze the post-big trip state of universes, concluding most universes in a multiverse are likely to be in a specific state with equation of state parameter w = -1/3.

Contribution

It demonstrates that the maximal probability state after a big trip corresponds to w = -1/3, providing a novel quantum cosmological insight into universe evolution.

Findings

Most universes after big trip are in the state with w = -1/3.

The probability of other states is minimized.

The result is derived from Wheeler-DeWitt wave equation analysis.

Abstract

The big trip can be describe with the help of the Wheeler-DeWitt wave equation ${\hat H}\psi(w,a)=0$. The probability to find the universe after big trip in the state with $w=w_0$ will be maximal if $\partial\psi(w,a)/\partial w|_{w=w_0}=0$ for any values of the scale factor $a$. It is shown that this will be the case if and only if $w_0=-1/3$. This fact allows one to suggest that vast majority of universes in multiverse must be in this state after their big trips.
