Where are the space aliens? Don't worry, they are here!
Maybe the big natural activities of those beyond Earth just happens to look exactly as if they are not there. Hanson said it seems rather unlikely, as it would be a “remarkable coincidence” if advanced artificial processes were actually responsible for all the astronomical phenomena we do explain from natural occurrences,- from pulsars to dark matter
In before the Ancient Aliens memes!
I’d imagine we will eventually run into aliens that have visited many planets and we will find out that they are ardent anti-communists because they found so many extinct civs that became communist right before they went extinct...
I always thought there should be a multiplying factor to the Drake equation, whose value is 1 or 0. And the factor is if God wanted their to be life elsewhere. 1 if yes, 0 if no.
Maybe there simply aren’t any alien civilizations. I personally don’t doubt there’s life but would prefer that they weren’t intelligent.
The ET’s saw our politicians and immediately put a quarantine around earth so we can’t contaminate them. That’s your Great Filter.
I’m skeptical on the existence of alien civilizations. Fermi’s Question “where are they?” is compelling. My big laugh is the “contactee.” Here one has a civilization investing their wealth in developing and manufacturing a space ship, training a crew, then embarking on the extremely dangerous journey across interstellar space all to contact Joe Shlunk in a cornfield at 3:00 A.M. Joe Shlunk’s local time.
Maybe if half the astrophysics community didn’t take the approach of global warming ‘scientists’ we might have an answer. Instead, they play the same games, politics ect with their papers/journals, backbite each other and do little actual science.
Only recently could the mere IDEA that aliens ‘could’ exist be spoken in public without the entire community coming down on itself.
Lastly, Scientists aren’t as smart as they think they are. 500 years ago they were putting each other in jail for hersey. They only barely grasp the generalities of the big things they can see on a cosmological scale, much less fully understand them. Overall, they are like a kid with his first copy of Guitar World thinking he can play Steve Vai solos after reading the interview.
The “great filter” is distance. It’s a long way from here to anywhere, our radio traffic (the most distantly traveled part of our civilization, going relatively fast and starting early) has traveled through an insignificant percentage of our galaxy.
Here’s the scale to really get it:

And of course that’s one way, if somebody near the edge of that heard us recently and sent a reply we’ll find out around 2100. And that’s with all kinds of assumptions about them having the technical specs to do it (we only use a fraction of the possible carrier wave spectrum), were actually listening, or care about the implications.
If there are billions of galaxies, and the distance between most of them are hundreds of millions of light years then two things are fairly certain. 1)There no doubt are many civilizations out there.2) Given the laws of physics and the fact that the speed of light is the universal speed limit, there is no way any biological entity or mechanical construction from an alien civilization has ever or ever will visit earth. However Earth has been transmitting data in analog form for over one hundred years and in algorithmic digital form for over thirty. It is quite possible that alien civilizations have linked up with one another by relaying data (with long travel times) to each other. Perhaps in thirty years or so some computers on earth will be “infected” with a truly wondrous virus.

Far too many speculations based on wrong assumptions about the universe in that article...
I think we were already visited by aliens from outer space. They didn’t like what they saw so they don’t come back anymore.
The Berserker Theory was interesting but the problem I see with that is that a psychotic killer race of beings couldn’t cover the distances to stamp out life everywhere in the galaxy. Then there are other galaxies we might see signs of artificial phenomena from. Unless the theory is that every galaxy has a Berserker race in it that manages to extinguish all other advanced cultures before they produce an identifiable trace of themselves. Sounds extremely unlikely.
How about we are just in a crappy location. We are all alone (as opposed to being in a nebula) at the edge of spiral Arm, 2/3 on the way out.
Essentially, in Galactic terms, we are in the middle of nowhere in South Dakota.
The whole galaxy could be filled with life that talks to each other, but we are just so far away from it all
