@ARTICLE{10.21494/ISTE.OP.2022.0797, TITLE={Do beings with strange behaviours live in the stars?}, AUTHOR={Michel Kreutzer, }, JOURNAL={Art and Science}, VOLUME={6}, NUMBER={Special issue}, YEAR={2022}, URL={http://openscience.fr/Do-beings-with-strange-behaviours-live-in-the-stars}, DOI={10.21494/ISTE.OP.2022.0797}, ISSN={2515-8767}, ABSTRACT={Humans propelled into another galaxy, setting foot on an exoplanet favourable to certain forms of life, could they interpret the behaviour of the beings inhabiting this extra-terrestrial universe? No doubt, because in spite of the great diversity of forms that these creatures could take, the necessities of life, such as subsistence and reproduction, impose identifiable behaviours. Under the infinite variety of possible behaviours, a small number of determinisms constitute living invariants.}}
