TL;DR
This paper revisits the chaotic behavior of the mixmaster cosmological model, correcting previous methodological oversights to conclusively determine its chaotic nature.
Contribution
It improves upon prior methods by addressing key oversights, providing a more definitive analysis of the mixmaster universe's chaos.
Findings
Confirmed the chaotic behavior of the mixmaster universe
Corrected previous methodological oversights
Provided a more conclusive analysis of chaos in cosmology
Abstract
The significant discussion about the possible chaotic behavior of the mixmaster cosmological model due to Cornish and Levin [J.N. Cornish and J.J. Levin, Phys. Rev. Lett. 78 (1997) 998; Phys. Rev. D 55 (1997) 7489] is revisited. We improve their method by correcting nontrivial oversights that make their work inconclusive to precisely confirm their result: ``The mixmaster universe is indeed chaotic''.
