# Comment on 'Accelerated observers emerging from a Bose-Einstein condensate through analogue gravity'

## TL;DR

This paper critiques the applicability of the analogue gravity model to Bose-Einstein condensates in anisotropic traps, questioning its realism in simulating accelerated observers and highlighting issues with physical units.

## Contribution

It provides critical analysis and evidence challenging the validity of the analogue gravity analogy in certain BEC configurations.

## Key findings

- Analogue gravity does not work for anisotropic BEC traps
- The analogy with accelerated observers is not realistic
- Physical units introduce loopholes in the analogy

## Abstract

Few comments upon Gonzalez-Fernandez and Camacho paper (arXiv: 1904.02299) are pointed out. We bring evidences that the analogue gravity recipe does not work for a BEC in an anisotropic harmonic-oscillator trap. The analogy with an accelerated observer does not seem to be realistic. Some loopholes related to the physical units are emphasized.
