- jcims 8y agoExactly. The 'L' term at the end (length of time advanced civilization is transmitting detectable signals) may be a very small window for most civilizations. Energy is precious. If you have the technology to put the signal where you want it to be, why would you spew it all over the universe?
- pattisapu 8y agoGood points--but you might still spew out your signal out all over the universe if you were still searching for advanced life.
