The 7 Least Plausible Solutions To The Fermi Paradox

One of the greatest conundrums to face humanity is the question of extraterrestrial life. Many explanations have been posited over the years to explain why we have yet to make first contact, some better than others.

And in fact, some astrobiologists theorize that all advanced civilizations hit the same insurmountable developmental wall we have. They call… » 12/21/12 11:00am 12/21/12 11:00am

Does a galaxy filled with habitable planets mean humanity is doomed?

Last week, we reported on the astounding confirmation that all solar systems in the Galaxy probably have planets, and that Earthlike planets are more common than previously thought. While this seems like good news for SETI-enthusiasts, the revelation is actually quite disturbing. » 6/18/12 2:20pm 6/18/12 2:20pm
