re: #463 Hecuba’s daughter

Possible reasons for no detection of other intelligent civilizations:
1. All technological civilizations self-destruct within 100 years. So a lot are created but the evidence of their existence doesn’t overlap with our ability to detect them.
2. After a few years, due to improved technology, planets no longer emit signals that can be detected by others.
3. No reason for intelligent species to be technological.

At one time we thought planetary creation was an extremely rare event.

We’ve been a technological civilization for a few thousand years, unless you mean once we are able to broadcast radio waves.
