From SEO Theory: SERP-based Communication Protocols https://t.co/YcAuoCdh3h #contenttheory
Recent astronomical discoveries make it seem more likely there are life-bearing planets within only a few hundred light-years of the Sol system, but if there are any intelligences on those planets we have discovered or will soon discover in nearby star systems, communicating with them would still take a very long time. One of the most likely planets to be capable of sustaining Earth-like life (which might communicate in ways similar to the myriad ways creatures on Earth do) is located less than 15 light-years from us. Theoretically, most of us might be able to hear a reply to any communication we attempt to send that planet — if it has an intelligent civilization on it.
