(34,138 posts)Seriously, I have had people give directions with landmarks that no longer exist. "Watch out for the corner where the house collapsed thirty years ago."
Now that I am getting older and have lived in the same place for decades I find myself having to fight that tendency. But in my case my memory of a route is much more likely to include landmarks that have been torn down and replaced by something completely different.
Where I used to say "Turn right just past the old Bradfordville School Building" for a while I had to say "Turn right at the seafood restaurant" and now it is "Turn right just before the Target store." Plus the number of street lights keeps growing. It used to be almost ten miles from the last street light to the turn to get to our farm. Now there are several street lights on that same route and they have added a turn since they re-routed the road!

(11,175 posts)The misshapen asterisk on the left is an attempt to tell where we are, when the hypothetical viewer doesn't know any Terran language. It's keyed to 14 known pulsars. The pattern of dots and dashes gives the period of each pulsar, using the hydrogen spin-flip transition frequency as the unit (as made clear, it is hoped, by the little hydrogen atoms above it). The length of each line is the distance from that pulsar to here. See this Wikipedia page for further information.
As you said, the diagram at the bottom shows that we live on the third planet of the system.
The image at the right shows what we look like. This image was on plaques attached to the Pioneer 10 and 11 spacecraft, so the outline of the spacecraft, at the same scale as the images of the humans, enables the hypothetical alien viewer to know how big we are.
