Here’s a question: what if we flipped the whole “search for alien life” on its head and asked How Far Away Could We Detect… Ourselves?
A fledgling space-travelling civilization similar to ours may be out there somewhere in the Milky Way. Maybe they have their own fledgling SETI program, complete with radiotelescope arrays scanning the sky for the telltale signs of another technological civilization.
If there is, and if they do, from how far away could they detect our technosignatures? New research is asking that question.
Answer? Very far away!
Better check my work for typos again, because you never know who might see this! 😉
