I've always loved this graphic. How far out into the galaxy have our radio broadcasts traveled in the last 100 years? The yellow dot is the extent of it.

Yeah, it’s pretty mind boggling. You think “100 light years, clearly our signals should have gotten somewhere” then you look at that picture and it kind of shuts that down. And of course the punchline is we MIGHT have actually made contact, and they MIGHT have answered, and it hasn’t gotten here yet. If somebody got our signal 25 years ago and sent a reply we’ll get it in 50 years.
