I guess it wouldn't get a notice in earlier than 20 hours if Voyager collides into something as antenna would be damaged and signal goes dark.
I kind of wondered if an intelligent lifeform found voyager would it now how to pull down the sounds from a record?
I don't think they left instructions on how to listen to the material.https://www.nasa.gov/content/mementos-of-earth
If they did, is an alien going to know how to read English?
