Currently reading a book about the science behind scifi. It’s a great book and I’ll give it a good write up once I finish it.
Anyway, while reading a chapter on search for extraterrestrials, I got curious about the history of radio and tv signals and how far they’ve made it so far. A Google search led me to two websites with really amazing information.
The first was a link on the Planetary Society’s webpage, which demonstrated with a map of the Milky Way how far Earth signals have made it into space. Emphasis on the Milky Way there because even within our own galaxy, signals haven’t gone very far.
The second was a website called ETTV. ETTV is Extraterrestrial Television. Using today’s date as a starting point, it maps out radio signals from Earth and demonstrates with examples what tv programs would reach some of the planets in our galaxy that are projected to support life.
The book is fantastic and started out as a library book that I felt was a must own for anyone interested in scifi writing. I rushed out to buy my own and am working my way through it.
