Expanding Advanced Civilizations in the Universe
Yet more catching up:
astro-ph/0501119 Date: Fri, 7 Jan 2005 12:57:15 GMT (124kb) Title: Expanding advanced civilizations in the universe Authors: Claudius Gros Subj-class: Astrophysics; Other Journal-ref: J.Br.Interplanet.Soc. 58 (2005) 108 The 1950 lunch-table remark by Enrico Fermi `Where is everybody' has started intensive scientific and philosophical discussions about what we call nowadays the `Fermi paradox': If there had been ever a single advanced civilization in the cosmological history of our galaxy, dedicated to expansion, it would have had plenty of time to colonize the entire galaxy via exponential growth. No evidence of present or past alien visits to earth are known to us, leading to the standard conclusion that no advanced expanding civilization has ever existed in the milky-way \cite{Webb}. This conclusion rest fundamentally on the ad-hoc assumption, that any alien civilizations dedicated to expansion at one time would remain dedicated to expansions forever. Considering our limited knowledge about alien civilizations we need however to relax this basic assumption. Here we show that a substantial and stable population of expanding advanced civilization might consequently exist in our galaxy. -- Lt.

Very good point, it could well be mans great need for prosperity and
expansion that cause it to be destroyed, if we dont consider the consequences of our actions "Martin 53N 1W" wrote in message ...
