The study concludes that less than 1-5 technoemissions are expected per century across the entire galaxy. This implies a significant probability that the Earth occupies a “void zone” devoid of alien signals. There is a 50% probability Earth will not be illuminated by any technosignals for 60-1800 years.
The analysis makes simplifying assumptions about isotropy and spatial distributions of emissions. It also focuses only on electromagnetic signals like radio waves, not physical artifacts. But the study provides an interesting perspective using the lack of SETI detection as evidence.
A depressing answer can be found in the Fermi Paradox. Somehow, despite the billions of years of existence of this universe, no technological civilisations have emerged to send transmissions, despite the maths saying we should be seeing something out there. And with how we’re backsliding to a political model that the entire world had to fight a hundred years ago, there may be an answer to that. The most strangest of games: Global Thermonuclear War. Remember, the only winning move in that game is not to play.
