Piloto de Podcast

Ainda não temos nome. Ainda não temos formato. Nem assunto temos. Mas no último domingo, Antônio Carlos Roque, Luciano Bachmann, George Cardoso e eu fizemos um piloto, regado a muita comida e vinhos na casa do Roque.
Conversamos das 11h às 21h, Ufa! Mas só gravamos duas horas e meia. Vou colocar alguns pedaços para degustação. Se alguém tiver ideia para o nome do Podcast, deixe no comentário por favor!

Paradoxo de Fermi e ETs

Persistence solves Fermi Paradox but challenges SETI projects

Osame Kinouchi (DFM-FFCLRP-Usp)

Persistence phenomena in colonization processes could explain the negative results of SETI search preserving the possibility of a galactic civilization. However, persistence phenomena also indicates that search of technological civilizations in stars in the neighbourhood of Sun is a misdirected SETI strategy. This last conclusion is also suggested by a weaker form of the Fermi paradox. A simple model of a branching colonization which includes emergence, decay and branching of civilizations is proposed. The model could also be used in the context of ant nests diffusion.
