I don't understand the focus of the article being on sending a physical probe. Why not just send a radio message? Something like "Is there anybody out there?"

I've heard the argument that we shouldn't advertise our existence in case there are hostile beings. But can't we assume that all intelligent life is constrained by the same rules of physics? And why assume hostile?
- scott_karana 10y agoThe round trip time for such a message would be 9.0 year, so getting our signal discovered, and getting it mutually intelligible, could easily never happen, even if there was life there.
- dredmorbius 10y agoClearly, part of the trick would be to figure out what to send, and to keep sending it. Well, that, and figuring out how to send it. Though when you've got the resources of a habitable planet at your back, generating strong signals seems more viable.
