[QUOTE="BrownArmy, post: 4182347, member: 18225"] It’s not necessarily about climate change (although that’s our problem)... The question is, where is everyone else in the Universe? Just in our own Milky Way galaxy, a reasonable projection is 10-20 spacefaring civilizations. But there are 100,000,000,000 galaxies. The odds that we are the only sentient beings to have ever evolved are scant. In our own galaxy, if other planetary civilizations didn’t leave their planet, at least there would be radio waves that we’d pick up. Yet, nothing. The question is, why? It’s entirely possible that spacefaring civilizations did or will exist in our own galaxy, but they died out or haven’t been born yet (after all our sentient time on the Earth hasn’t been all that long). So, the ‘Great Filter’. Either we’re truly special (unlikely), or we’ve not heard from anyone because they are displaced from us in time, or no civilization has been able to leave their planet. Look at Earth, do we seem poised to concur our own Solar System, or move beyond? Sadly, no. The answer to ‘Fermi’s Paradox’ is that everyone who could have possibly contacted us died in their own political/environmental filth. Sad. [/QUOTE]
