<br><br>Here's the photo:<br><br><a href="http://www.space.com/17755-farthest-universe-view-hubble-space-telescope.htm">http://www.space.com/17755-farthest-universe-view-hubble-space-telescope.htm</a><br><br>>…Doesn't this photo make the Fermi paradox even more problematic? Given the ginormous number of stars out there, and given that, once you achieve interstellar capability, extragalactic adventure is not that far away (i.e. the distance to Andromeda is only 20x the diameter of our Milky Way, and what's an order of magnitude between friends?), why don't we see even a damned single photon out there that even remotely smells artificial? The more we know about the cosmos, the more puzzling this problem becomes…Alfio<br>
<br> <br><br>Alfio, how many postcards have you written to Aboriginal pen pals in the Australian outback? Neither have I. During Extro5, I kept starting one, but more interesting immediately adjacent conversations kept distracting me, and furthermore I kept being overwhelmed by the fact that I don’t know where to send the card, I don’t know their language, I don’t know their customs, I have no clue how to even start to explain to them the very basics they must understand to even vaguely grok what it was we were doing there. Even I only vaguely grok what we were doing there, with decades of preparation. The Australian aboriginals have never received a single postcard from me, even though the cost to send one would be minimal.<br>

The problem is not only radio silence, but also the lack of artifacts or any sign that, at the stellar scale and over, things do not simply follow the laws of entropy. A telltale sign of life on Earth is chemical disequilibrium: something is actively keeping the atmosphere out of balance, filling it with oxygen. Skyscrapers and airplanes are the same: someone is working to hold them up, and they would revert to their "natural" state quite readily if the upkeeping ceased.</div>
<div>It seems quite obvious that, for some reason, technology does not reach megascale proportions. I don't know, maybe when you get to the scale at which self-gravity is significant, it might be hard to go on. Or the intervention is subtle enough that what we think is an untouched landscape is in fact a byproduct of it. Or maybe there's no general need for such wide scale activity, for reasons we still have to discover. Who knows.</div>
