@ARTICLE{10.21494/ISTE.OP.2022.0795, TITLE={A brief comment based on astrophysics}, AUTHOR={Jean Audouze, }, JOURNAL={Art and Science}, VOLUME={6}, NUMBER={Special issue}, YEAR={2022}, URL={https://openscience.fr/A-brief-comment-based-on-astrophysics}, DOI={10.21494/ISTE.OP.2022.0795}, ISSN={2515-8767}, ABSTRACT={This comment summarizes the main astrophysical arguments according which it seems likely that there exists living complex beings located on a few extra solar planets and that some of them can be considered as « intelligent ». Nevertheless, it is impossible to prove their existence. Therefore the scientific and artistic considerations about their possible structures are and will be purely imaginative.}}
