The Milky Way could be teeming with interstellar alien civilizations — we just don't know about it because they haven't paid us a visit in 10 million years.

A study published last month in The Astronomical Journal[$] posits that intelligent extraterrestrial life could be taking its time to explore the galaxy, harnessing star systems' movement to make star-hopping easier.

The work is a new response to a question known as the Fermi paradox, which asks why we haven't detected signs of extraterrestrial intelligence.

    I'm not assuming it's unbounded. I am assuming that it's no worse than it was in the prior century. You're absolutely right we aren't monitoring every possible angle constantly. But there are a large number of observation points and there have been for 40 years or more. And there should be a nearly infinite number of signals for them to detect. Yet not a single signal has been detected. You don't need to assume anything near perfect observation for this to seem odd.

    Wrong track again. Verify your 'capabilities of detection' assumptions some more.

    (not gonna involve myself in this argumentation anymore until you do your homework)
