One of the terms is literally “L = the length of time for which such civilizations release detectable signals into space”. Which is to say that no alien civilization is expected to last forever and maybe not even for that long (barring any mitigating factors of course).
I wonder how many alien civilizations also died slap-fighting each other as their planet burned down.
Our data currently shows 100%
Tell the Lieutenant Commander to double check that.
This is actually a part of the calculus that goes into figuring out “where the hell are all the interplanetary civilizations at?”
