THIS is fascinating. Of course, the naysayers will immediately try to "debunk" it, but then again they insisted the earth was flat at one time as well...

Surely, we humans are not the only intelligent life forms in the universe. The universe is very very big. Billions of galaxies. And even in our own galaxy there are hundreds of billions of stars. And the number of habitable planets? More than you can imagine. Anyone who thinks the universe has no other intelligent beings needs to rethink things. They have to be out there.

The big problem is this: is interstellar travel possible? In 1977 two space probes were launched. They're just now reaching the edge of our solar system. And to reach the nearest star system? Thousands of years. So we can't even visit the solar neighborhood with out present technology.

Someone needs to get to work on a warp drive....

Most likely there's a natural explanation, but we can always hope. It sounds like the kind of signature we might see for a star surrounded by a Dyson swarm:

When pulsars were first discovered, the possibility of their being interstellar beacons was discussed. But the presence of a pulsar at the heart of the Crab Nebula proved otherwise:

So the weird pulsing of the pulsars turned out to have a natural explanation - the aftermath of supernovas. Regarding warp drive, there are people in NASA thinking seriously about it and running experiments;

You have to take in to account the experts said it MAY be a mega-structure. Until we develop a way to cross the mass expance of space we wont know one way or the other. All speculation at this point.

Did anyone notice the magnitude of the stars dimming? We're not talking 0.005% or something (Jupiter would cause about a 1% dimming). The dimming of KIC 8462852 was a staggering 22%! (15% the first time).

Whatever the cause, the objects that are crossing the star appear to be enormous. Hard to reconcile that with a cometary swarm or the other hypotheses being put forth.

Regarding the need to physically go there, they're pushing to get radio telescope time to investigate; if they detect the alien equivalent of I Love Lucy, case closed. If they don't, that either says no aliens or the aliens no longer use radio waves for communication.

Which doesn't exactly fit with the many posts in this forum that claim science and the government are in collusion to hide the real truth from the public.

However, I don't think the article is particularly useful or accurate:

the author confuses hypothesis with theory (something I wouldn't expect from a "futurist" who claims to be qualified to speak on SETI and has proposed we take apart Mercury to create our own Dyson sphere);

Lowell's mistake was I think understandable given the state of technology at the time, since seasonal changes were observed on Mars and the human vision system tends to seek patterns like lines in ambiguous data;

the pulsar, Wow! signal, and peryton observations were thought to be interesting and worthy of further investigation at the time but as Jocelyn Burnell said, "we did not really believe that we had picked up signals from another civilization, but obviously the idea had crossed our minds" -- that is, there was a possibility of a non-natural explanation which in two of these cases was shown to be the case -- proof that science works (the Wow! signal is still unexplained, and will remain so, since science doesn't deal with non repeatable events).

finally, the author throws UFOs into the mix -- how are UFOs an example of "The Many, Many Times Astronomers Mistook Mundane Phenomena for Aliens"? When exactly did one or more astronomers mistake UFOs for aliens?

Is it not possible that an object in our own solar system passed in front of the star in question? Or even a piece of space junk in the earth's own space junk cloud?

There have been hundreds of dimmings at irregular intervals, some blocking 15-20% of the star's output or more. Not just one event. None of the other 150,000 stars observed have shown this behavior. So that would have to be one selective cloud of earth orbit space junk.
