Evo-SETI: life evolution statistics on Earth and exoplanets
No full textThis book offers a vision of how evolutionary life processes can be modelled. It presents a mathematical description that can be used not only for the full evolution of life on Earth from RNA to modern human societies, but also the possible evolution of life on exoplanets, thus leading to SETI, the current Search for ExtraTerrestrial Intelligence. The main premise underlying this mathematical theory is that the Geometric Brownian Motion (GBM) can be applied as a key stochastic process to model the evolution of life. In the resulting Evo-SETI Theory, the life of any living thing (a cell, an animal, a human, a civilization of humans, or even an ET civilization) is represented by a b-lognormal, i.e., a lognormal probability density function starting at a precise instant (b, birth) then increasing up to a peak time, then decreasing to senility time and then continuing as a straight line down to the time of death. Using this theory, Claudio Maccone arrives at remarkable hypotheses on the development of life and civilizations, the possibility of extraterrestrial life, and when computers will take over the reins from us humans (Singularity). The book develops the mathematical Evo-SETI Theory by integrating a set of articles that the author has published in various journals on Astrobiology and Astronautical Research
"La vida en el universo": The Oxford templeton visiting fellowship to Peru about SETI and bioastronomy
No full text"La vida en el universo: su origen, su naturaleza, su sentido" ("Life in the universe: its origin, its nature its meaning") is a Peruvian project about SETI and Bioastronomy which has been awarded one of the six Oxford Templeton Visiting Fellowships to Latin America offered by the Ian Ramsey Centre for Science and Religion at the Oxford University and the John Templeton Foundation for the year 2017. The project, which was both research, teaching and dissemination, has been proposed by two Universities of Lima, the UCSS (Universidad Católica Sedes Sapientiae) and the UNIFÉ (Universidad Femenina del Sagrado Corazón), and has been developed by the Visiting Fellow (i.e. Dr. Paolo Musso) from 20 February to 30 April 2017 in the Peruvian cities of Lima and Atalaya. The main topics to be investigated were: a) the relationships between the conditions required for the origin of life and the conditions required for the origin of universe; b) the philosophical and religious implications of the possible existence of life in other parts of the universe; c) the problem of the universality of reason, with a special focus on intercultural communication. The main activities of the project were: 1) a course of specialization for professors and students about the search for life in the universe; 2) a seminar about the origin of the universe and the origin of life; 3) a research work on interculturality to be developed in the UCSS Amazonian seat of Atalaya (called UCSS Nopoki); 4) an international congress about all the topics of the project with the participation of distinguished experts of SETI and Bioastronomy, who were to be put in touch with the local researchers in these fields. The present paper will account for the main outcomes of the projects and the future perspectives

No full textAstrobiology and SETI in Peru: recent and future advances
No full textIn a previous paper presented at the IAC 2020 we spoked about a Peruvian project about Astrobiology and SETI. Unfortunately, the project was stopped for two years by the Covid pandemic, but we are now resuming it. The project is carried out by a group of professors of the Faculty of Physical Sciences of the San Marcos National University in collaboration with the InCosmiCon research center, and it moves along three main lines: 1) creating the first Peruvian School of Astronomy at the San Marcos National University in Lima, where Astrobiology will be one of the programs of the school; 2) activating the first Peruvian Optical SETI program at the new astronomical observatory that the San Marcos National University is currently building in Cusco; 3) carrying out a series of studies about some crucial topics of Astrobiology and SETI, like the extension of the galactic habitable zone, the encoding of advanced mathematics in interstellar messages, and the ongoing experience of intercultural dialogue at the Amazonian University UCSS-Nopoki of Atalaya as a possible model for interstellar communication. In this paper we will account for the recent advances already made and those expected in the next future

No full textA Peruvian project about astrobiology and optical SETI
No full textThe Peruvian SETI group effort in the study of extraterrestrial intelligence is reported. This effort is twofold, namely the optical SETI Observatory and the theoretical implications for the life of the recent discovery of earth-like exoplanets. The work focuses on the development of astrobiology, especially in the study of the stellar and galactic habitable zone and dynamics of the universe appropriate for the development of life, and as part of these activities, in 2017 we organized the astrobiology school. As part of IAA SETI, our main objective is to present a project to the Peruvian funding scientific institution (CONCYTEC) for the acquisition of a medium-sized optical telescope to be part of a global network of modest-sized Optical SETI observatories. Furthermore, we will continue with our theoretical investigation in astrobiology, focusing not only on extension of the galactic habitable zone but specially, on the importance of the recent discovered earth like exoplanets
Deep Space Flight and Communications: Exploiting the Sun as a Gravitational Lens
No full textThe majority of books dealing with prospects for interstellar flight tackle the problem of the propulsion systems that will be needed to send a craft on an interstellar trajectory. The proposed book looks at two other, equally important aspects of such space missions, and each forms half of this two part book. Part 1 looks at the ways in which it is possible to exploit the focusing effect of the Sun as a gravitational lens for scientific missions to distances of 550 AU and beyond into interstellar space. The author explains the mechanism of the Sun as a gravitational lens, the scientific investigations which may be carried out along the way to a distance of 550 AU (and at the 550 AU sphere itself), the requirements for exiting the Solar System at the highest speed and a range of project ideas for missions entering interstellar space. Part 2 of the book deals with the problems of communicating between an interstellar spaceship and the Earth, especially at very high speeds. Here the author assesses a range of mathematical tools relating to the Karhunen-Loève Transform (KLT) for optimal telecommunications, technical topics that may one day enable humans flying around the Galaxy to keep in contact with the Earth. This part of the book opens with a summary of the author’s 2003 Pešek Lecture presented at the IAC in Bremen, which introduces the concept of KLT for engineers and ‘newcomers’ to the subject. It is planned to include a DVD containing the full mathematical derivations of the KLT for those interested in this important mathematical tool whilst the text itself will contain the various results without outlines of the mathematical proofs. Astronautical engineers will thus be able to see the application of the results without getting bogged down in the mathematics
