Salvador Robles-Perez, Prado Martin-Moruno, Alberto Rozas-Fernandez,, Pedro F. Gonzalez-Diaz
TL;DR
This paper explores cosmological models with dark and phantom energy in a universe with negative cosmological constant, revealing infinite singularities that suggest multiverse scenarios and relate to the universe's acceleration.
Contribution
It introduces new solutions for universes with dark and phantom energy under negative cosmological constant, highlighting their singularity structures and multiverse implications.
Findings
Solutions contain infinite singularities along time
Singularities include big bang/crunches and big rips
Models relate to current accelerating universe
Abstract
We present cosmic solutions corresponding to universes filled with dark and phantom energy, all having a negative cosmological constant. All such solutions contain infinite singularities, successively and equally distributed along time, which can be either big bang/crunchs or big rips singularities. Classicaly these solutions can be regarded as associated with multiverse scenarios, being those corresponding to phantom energy that may describe the current accelerating universe.
