The Fermi Paradox
A few weeks ago, I began a discussion about the Kardashev scale. The Kardashev scale builds levels of technology that represent advanced civilizations, mostly beyond our own. Given the technology scale, and speculation from science fiction, we can scale possible galaxy crossing times.
The galaxy crossing times can also be connected to a civilization’s colonization time for the galaxy. Once we get those numbers, it becomes apparent that the colonization time is small compared to the age of the universe. Enrico Fermi noticed that the galaxy crossing time is small compared to the relative age of the universe. Hence the paradox. We should be in contact with aliens, but we aren’t. There’s more to the paradox, but at the most general — this is it.
In my article on the subject, It Starts With A Paradox, I discuss this in more depth.
Elizabeth Howell wrote an extensive article Is anybody out there? for space.com in December of 2021, that I highly recommend.
Another good article appears recently in Big Think, Where is Everybody? A new hope for solving the Fermi Paradox. It discusses the Square Kilometer Array (SKA) radio telescope, that may provide us a useful tool in answering this interesting science question.
Finally, this week. I’d like to leave my readers with an interesting question: In science fiction where faster than light (FTL) travel is the norm, what is the most plausible means of discovery of other FTL capable civilizations?
