Topic	Hmm...I suppose we are the only developed life in our galaxy

It's impossible to know what's happening in the near half a trillion stars spread over 100k light-years. It's stupid to even say anything final like that. I get that, my point is that when you put it that way you it is easy to say of course the galaxy is littered with life and civilizations. When you take another moment, and think through the biology that happened here and the probability of that happening bumped up against the likely number of other planets like us...you realize it may not be littered with life at all...in fact it may contain no life at all....then you look at the lack of evidence for life and complete and total improbability of a lack of evidence if life were common...and you realize we are likely alone. No, you're still underestimating here and making tons of assumptions, many bordering on science fiction much like Fermi and others. We are on the outer arm of the galaxy, pretty isolated from the center. There's no guarantee anything sent out on the other side would even reach us even given a million years because there's no guarantee a civilization would make Stargate-esque replicators to roam the galaxy because there's no guarantee we ourselves will reach that level, so why would other intelligent life? The Voyager 2 will reach the nearest star in 80k years. Civilizations could flourish and crumble in that time period. 14 billion years doesn't guarantee replicators. What's more likely is the the sheer distance keeps everyone isolated in their bubbles. Maybe some civilization colonized a few star systems. We would never know about it because we have no realistic way of knowing. You can't detect objects outside the solar system, so there could be bunch of shit floating around, and you have to be looking at signals/have to be aimed at you. Super advanced life is likely rare, but just intelligent life could be all around the galaxy without actually knowing the presence of the other. --- It all just disappears, doesn't it? Everything you are, gone in a moment, like breath on a mirror. - The Doctor <cite>DoctorVader posted [p:888826126] in Hmm...I su...
