TL;DR
This paper investigates the stability of a cosmological model derived from quantum potential, revealing that quantum corrections may cause perturbative instability due to additional parameters.
Contribution
It critically examines the perturbative stability of a quantum potential-based cosmology and identifies potential instabilities introduced by quantum corrections.
Findings
Quantum corrections introduce additional parameters.
These parameters can lead to perturbative instability.
The stability of the model is compromised by quantum effects.
Abstract
Apart from its debatable correctness, we examine the perturbative stability of the recently proposed cosmology from quantum potential. We find that the proposed quantum corrections invoke additional parameters which apparently introduce perturbative instability to the Universe.
