?Alien cliques? may be keeping Earth isolated - study
 

If the idea really is true that aliens are deliberately preventing humans from contacting them, then extraterrestrial civilizations most likely formed a number of cliques rather than a pan-galactic government, a new study suggests.

The Fermi paradox ? named after physicist Enrico Fermi ? says that if sentient life is not unique to Earth, then our galaxy should have plenty of other civilizations, including some more technologically advanced than ours. The paradoxical part is that we have not detected any signs of them.

A supposition called ?the zoo hypothesis? is one possible solution for this conundrum, and states that alien civilizations are for some reason deliberately keeping humans from detecting any extraterrestrial life.

One problem with this answer is that it would require the galactic community to form a united government to agree on and enforce such an information blockade. In a paper published online this week, astrophysicist Duncan H. Forgan used a model which showed that if there are indeed multiple civilizations in the Milky Way, they are much more likely to form a number of cliques than a single galactic club.

The model accounts for a number of factors, including the time when each civilization advances enough to participate in interstellar communication, the distances between their origin worlds, and the lifetimes of the civilizations.

?We find that for there to be only a single group (a ?Galactic Club?), the mean civilization lifetime must be extremely long, and the arrival time between civilizations must in fact be relatively short. This is perhaps an unlikely scenario, as it would require a large number of civilizations to emerge across the galaxy in a very short time frame,? the paper said.

The study also found that a single long-lasting civilization arriving early in the galaxy?s history would still be unlikely to knit all civilizations into a united club. But if all civilizations arrived relatively uniformly and lasted much longer than a million years, then such a club could exist.

A more likely scenario however is that there are multiple conflicting cliques of civilizations that cannot agree on a universal policy.

?One clique attempting to place an interdict on contacting ?primitive? civilizations is likely to encounter significant problems if another clique disagrees,? Forgan said.

?It may well still be the case that the Earth resides in a region of space occupied by a conservative clique bent on non-contact,? the paper added. ?However, as our ability to detect unintentional signals from both living and dead civilizations increases, we should presumably be able to break the deadlock imposed in this scenario.?

The paper was published on the pre-print website arXiv.org.

What a load of shit.

Sure...this proves they exist because we can't contact them.

I am sure that if they did exist they would let us join the cosmic club.

Face it...it is likely that we alone or at least alone as far as intelligent beings. The conditions that lead to the evolution of mammals might never happen again. Sharks have been around for 100 million years and never invented the iPhone. Might well be the case that there is life out there...just putting out a radio signal (sorry but even dolphins can't do that.)

We will never leave this planet. We will go extinct just like 99% of all the species who ever did naturally over time. The only difference is that will be the cause of our own extension either from habitat destruction or biological warfare or simply wiped out by a naturally occurring pandemic that we have no immunity to and can not stop.

The party was fun while it lasted.

That is definitely a pokemon...

Thanks Trump...

I'm absolutely convinced that humankind's brains are in our crotches. Because I'll say it again, the world was far less stupid dumb ass when no one shaved their pubic hair.

I hang my head in shame to have even clicked on this thread! I can't imagine what would motivate some moronic scientist(s) to write this crap. This is pathetic and the people believing this are even more pathetic.

What we need is a total economic meltdown followed by an outright war with China and Russia that brings back the military draft and food rationing. Only then will our brains migrate south of the crotch back into our head.

Its called the "internet" giving world stage to all the crazy conspiracy theorist. Rather than having to keep their idea of crazy to themselves in their basement, they can now spead them every where.

So they're basically the mean girls of the galaxy.

Somehow there were check and balances on the crazies. Hopefully Internet 4.0 sees the app revolution finally kill the web and all the crazies confine themselves to their conspiracy theory app.

I have to say that you hit the nail on the head and I agree with you. :thumbsup

Might get our species back on track at least long enough change the trajectory to extinction that we are on now.
