Reply to comment by ChrisARippel in If the Milky Way is located in the middle of a void, does this explain why we see no aliens? by [deleted]
Would u say that the possibility of a galactic wide civilization is not fully ruled out in our own milky way then. Their technology would have to be way more advanced then us to be able to cover a good portion of a galaxy so it very well could go undetected by our standards. There's a part of me that feels it's impossible for a civilization to colonize a galaxy, they are just so mindboggingly huge and vast. I just think by the time a race got to that point they were capable of doing it they would probably fit our description of a god like bejng and they wouldn't even be interested in doing something like that anymore.

I don't rule out the possibility of advanced civilization in the galaxy. The idea of a galactic civilization seems silly to me. Vastness of the galaxy you mentioned is one point. My point is why?
The Europeans looked for India and China because that is where the good stuff was and they wanted it. I think we imagine aliens would be explorers like Europeans.
The way more advanced Chinese had an earlier age of exploration in giant ships. They were generally unimpressed with what they found. Everywhere else was poorer and less advanced. They halted further exploration. An advanced alien civilization might be like Chinese and see little point in exploring the entire galaxy. The knee-jerk answers are more resources or curiosity.

How many planetary systems would an advanced civilization actually need?

How many planetary systems does an advanced civilization need to explore before it's been there, done that?
