But nothing at all is really known about "length of time for which such civilizations release detectable signals into space". It's somewhere between a few decades or so and 10 billion years?
- OscarCunningham 8y agoSure, which is one of the reasons why we don't currently have a Fermi paradox.
- EthanHeilman 8y agoTo me the Fermi Paradox isn't really a paradox it is framework for thinking about the problem. This research fits into that framework and provides an interesting new argument that the great filter is more likely to be in our past rather than our future.
- bena 8y agoIIRC, we're already going dark. The amount of "noise" we broadcast into space is diminishing. If other civilizations roughly follow the progress of our own, that could mean that the window a civilization has to be detected is something like 100 - 200 years.
