We all know Signal, Matrix, Telegram, SimpleX, etc... But if you can't access the internet you can't communicate. Pretty logic. But would it be possible, at least theoretically, to create an app that permits to message people even if the internet goes down?

It might be a dumb question I really have no idea to be honest.

SSB can use the internet to share encrypted messages via hubs/servers, but it also can share the same messages peer to peer in a mesh sort of setup without the internet using a 'gossip' protocol within a local network. It was invented by a sailor who was regularly away from WiFi due to being at sea.
