A new model shows how the spread of ET civilisations can undergo phase changes, providing a deeper insights into the Fermi Paradox
The result gives a new insight into the Fermi Paradox. Bezsudnov and Snarskii say that for certain values of these parameters, the universe undergoes a phase change from one in which civilisations tend not to meet and spread into one in which the entire universe tends to become civilised as different groups meet and spread.
The Fermi paradox is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence for, or contact with, such civilizations.
The Fermi Paradox is the apparent contradiction between the high probability extraterrestrial civilizations' existence and the lack of contact with such civilizations. In general, solutions to Fermi's paradox come down to either estimation of Drake equation parameters i.e. our guesses about the potential number of extraterrestrial civilizations or simulation of civilizations development in the universe. We consider a new type of cellular automata, that allows to analyze Fermi paradox. We introduce bonus stimulation model (BS-model) of development in cellular space (Universe) of objects (Civilizations). When civilizations get in touch they stimulate development each other, increasing their life time. We discovered nonlinear threshold behaviour of total volume of civilizations in universe and on the basis of our model we built analogue of Drake equation.
Scientists celebrated Sunday after finding more than 700 suspected new planets -- including up to 140 similar in size to Earth -- in just six weeks of using a powerful new space observatory.
Early results from NASA’s Kepler Mission, a small satellite observing deep space, suggested planets like Earth were far more common than previously thought.
Past discoveries suggested most planets outside our solar system were gas giants such as Jupiter and Saturn -- but the new evidence tipped the balance in favor of solid worlds.

Well, you are assuming(perhaps sarcastically) that advanced aliens would have destructive technology... when perhaps this is not the case. IMO it would be more logical to assume that they have since rid themselves of such technology otherwise they wouldn't have made it to the intergalactic level.
And, you are also assuming that they have never been here. IMO that is highly debatable and one of the most intriguing topics that will be answered someday in the not-so-distant future.
What if 'they' are behind what we call religion? I know, that sounds just like the History channel, but it is a good point, no?
