A civilisation billions of years more advanced than us should surely be putting out some sort of signal, intentionally or not, that they exist, right? And yet we've never seen any kind of signal like that. Space is incomprehensibly large and empty, and while I also absolutely believe that there is some other kind of life in the universe, the fact that we've never detected any means they've probably never detected us either, so there's no reason they would be coming here
- johnisgood 2y ago> the fact that we've never detected any means they've probably never detected us either I do not think that your conclusion necessarily follows. They could easily be much more advanced than us, just as we are much more advanced than we were 500 years ago.
- rbanffy 2y ago50 years ago we wouldn’t be able to detect today’s ourselves from Proxima Centauri. 500 years ago we would barely be able to do so from the Moon.
- johnisgood 2y agoI am just saying that there could be a more advanced whatever you may call it that could detect us while we cannot. Much more advanced to us than we are today.
