   I think the possibility that an extraterrestrial 👽 civilization might be malevolent is a good reason for us to start thinking about setting up self sustaining colonies on Mars and the Moon 🌙. And about building a mobile colony that could endure for enough time to reach Alpha Centauri and Proxima Centauri. As far as I know, we have not detected any planets 🪐 around either star ⭐️, but if they get there in a century or two and find a habitable planet 🌍, we will have made our species independent from Sol’s lifecycle … and from being obliterated by “greys” attacking earth.

      If Voyager 1 was headed for Proxima Centauri, it would take 73,000 years to reach it. Could we create a mobile and independent colony that could survive that long? Or would it need a boost in speed, so that journey could be shortened?

         How many breeding pairs of humans would be required? https://nu.federati.net/url/292680 [www technologyreviews com] (based on latest technology, so projected time is 6,300 years). Does not discuss the other creatures that would have to be carried.
