TL;DR
This paper investigates the theoretical possibility of a universe ending in a big smash singularity driven by superquintessence, a form of dark energy with w<-1, using a simple scalar field model.
Contribution
It demonstrates that big smash solutions are attractors in phase space within a superquintessence model involving a nonminimally coupled scalar field.
Findings
Big smash solutions are attractors in the model.
The model supports finite-time universe end scenarios.
Superquintessence can lead to catastrophic cosmic outcomes.
Abstract
The occurrence of a big smash singularity which ends the universe in a finite time in the future is investigated in the context of superquintessence, i.e. dark energy with effective equation of state parameter w<-1. The simplest model of superquintessence based on a single nonminimally coupled scalar field exhibits big smash solutions which are attractors in phase space.
