Abstract

VIEIRA, Frederico et al. Cosmic habitability and the possibility of life existence in other places of the universe. Rev. Bras. Ensino Fís. [online]. 2018, vol.40, n.4, e4308.  Epub June 18, 2018. ISSN 1806-9126.  http://dx.doi.org/10.1590/1806-9126-rbef-2017-0325.

This article discusses some aspects related to the concept of life as we know it and explores the relationship between the chemical evolution of the Universe and the production of the basic elements of prebiotic chemistry. Based on the Standard Cosmological Model, the cosmological conditions that led to the appearance of these elements are described and evidences are shown that the Universe, in its primordial stages, had elements capable of producing organic substances. Next section gives a short overview on how chemistry in astrophysical environments leads to the formation of compounds that are part of the chain of reactions that leads to the formation of the "bricks of life." Finally, we mention that the universe could have habitable zones from the first 30 million years and that the habitability condition has a close relation with its chemical evolution, even when one takes into account the hypothesis of different universes.

Keywords : Cosmic Habitability; Astrobiology; Astrochemistry.
