A new mathematical model suggests that any alien life in our galaxy is likely very young. That’s because of the high likelihood that intelligent civilizations “self-annihilate.” Oof! This research adds the dimension of relative age to an ongoing discussion about alien life.
In a new study, researchers suggest the answer to the Fermi paradox could be pretty bleak: Maybe all the intelligent civilizations have annihilated themselves. Jeez, 2020, that’s a little on the nose.
You love searching for the truth. So do we. Let’s find it together.
This is the Fermi paradox stated at its most succinct: The universe is unfathomably gigantic, but so far, we’ve never seen any sign that there’s intelligent life anywhere else.
We’ve never observed an extraterrestrial living thing, or uncovered any evidence for extinct ones. As we peer further out into our corner of the universe using more and more powerful telescopes, for example, people continue to hold out hope that we’ll find evidence of a civilization, Dyson sphere, or anything just around the next corner.
But there’s a problem with that line of thinking. A civilization that we’d see from this far away, let alone one that could have built something like a Dyson sphere, is likely to be peering back at us.

Why aren’t they sending telescope satellites through our part of space? And how can it be that out of all the planets and systems we’ve peeked into so far, we’ve seen nothing?
There are as many individual theories as there are theorists, and these run a huge gamut.
