Dyson Sphere hype.

Scientists , Astronomers are still trying to decipher  a strange astronomical anomaly .   A Dyson sphere or Dyson swarm may have been sighted in orbit of star KIC 8462852 .  Whatever it is be it natural or of intelligent design it is big enough to dim the star’s light by 22%, and is not orbiting periodically. When I read online the many articles posted on the subject , I find that not a single scientist made any critical judgement before saying that "they" found something of  (***)>>>intelligent design in outer space. It's important to note that the actual scientists studying the star aren't the ones screaming "ALIENS!" - that's the journalists who misreport and distort things to make them "sell better".Actually these are the actual scientists studying the star, they aren't screaming aliens but they do seem to be saying something like "we can't figure out how to model this with any natural phenomena so lets see if non-natural hypothesis fit".Is this as in like that star trek episode,where they build a wall around a solar system and it's sun? and capture all the energy let out? I really don't think this could happen.Your looking at creating matter out of nothing to make the panels....I thought the Dyson sphere was pretty much laughed about as a possibility There certain criteria that many have missed on this concept , so in this paper I will try to clear a few things.

The Criteria :
1st . A Dyson Sphere would require it's designers to be "humanoid" . It means that would have to have two arms , two legs , etc . 
2nd. Darwinian Evolution tells us,  that evolution can take many paths . "intelligent life"  may not look like us .
3rd. The Concept of a Dyson Sphere is a totally Human Concept .
4th.  ( ***)>>  We would detect radio signals , radiation .

The "problem" :
Completely impossible for the thing they discovered to be a Dyson sphere. A Dyson sphere envelops the entire star so we would not have seen the star If they had a Dyson sphere. If they have a Dyson sphere like this picture the whole ide of the sphere is useless since it would not capture the entire energy of a star. Now a Dyson ring or a Dyson Web is something else which is more likely.

KIC 8462852 is 1.480 light years away, that image the telescope is having was the light produced by that star 1.480 years ago, literally that happened when we haven't even discovered the new continent and we were still fighting with swords and arrows, I just imagine how would it look in the next 1.480 years?....

What The  Theorists are saying :
Many readers have openly questioned why the behavior of the light from the star KIC 8462852 is so unusual, and they centered on the sci-fi theory of a Dyson Sphere of alien superstructures encircling the star in order to harness its energy. But if anything, a Dyson Swarm—a loose collection of a structures rather than a solid sphere—is far more likely, given the immense amount of material needed to encapsulate a star from an immense distance. And while some are saying that this star could be harboring a giant structure built by an advanced alien civilization, the scientists behind the hype are saying otherwise. Right now, the only scientific information astronomers have for star KIC 8462852 is its light curves, which is an estimate of how much light Earth receives from the star over a given period of time. Right now, the only scientific information astronomers have for star KIC 8462852 is its light curves, which is an estimate of how much light Earth receives from the star over a given period of time. These light curves reveal that something giant, about half the width of the star, is blocking the light but in bizarre bursts that are anything but periodic. If the obstruction were a planet eclipsing the star, it would block the light with a predictable pattern as the planet orbited the star.But "the eclipses have very strange shapes in the sense that whatever is blocking it is not a circular object," And there's lots of them — lots of things blocking the star. When you put all that together, there's nothing like that [anywhere else] in the sky. It's unique and very very strange." If it were a literal Dyson’s Sphere, then the stars light would be blocked entirely, or constantly. If it were a Dyson “swarm,” the objects collecting solar energy would likely be too small and too few in number to obfuscate the star’s light in a manner detectable 1480 light years away. Also, Dyson’s “swarm” would cause the star to blink in a recognizable pattern due to the uniform spacing of each satellite in orbit.

Dyson Spheres : More Fiction than Fact.
 Freeman J. Dyson first explored this idea as a thought experiment in 1960. Dyson’s two-page paper in the journal Science was titled Search for Artificial Stellar Sources of Infrared Radiation because he was imagining a solar-system-sized solar power collection system not as a power source for us earthlings, but as a technology that other advanced civilizations in our galaxy would, inevitably, use. Dyson proposed that searching for evidence of the existence of such structures might lead to the discovery of advanced civilizations elsewhere in the galaxy, and indeed, in 2013, several groups of astronomers have begun a search for the telltale signs of Dyson spheres.  (2)>>Star Trek : TNG episode, "Relics" was large enough to support the life of 4 million earth sized planets, if you do some rough math, that's billions upon billions of people (potentially 24 quadrillion people), and 3,999,750 more planets than all the member planets of the federation, yet, they find it uninhabited, abandoned, and somehow have no clue who built it, or where they went. You could have literally fit the entire population of the federation of planets inside this sphere (if the star inside the sphere had not been unstable and emitting deadly amounts of radiation), and they would only have occupied about 0.0000375% of it's surface area. How is it possible that no one in the known galaxy knows about this megastructures history, or it's former inhabitants? The starship Enterprise, responding to a distress call, drops out of warp to discover a nearby Dyson sphere. They trace the distress call to the USS Jenolen, a Federation transport ship that has been reported missing for 75 years, and which has crashed intact on the sphere's outer hull. Commander RikerChief Engineer La Forge, and Lt. Worf transport to the Jenolen while the Enterprise investigates the sphere. La Forge discovers that the Jenolen‍ '​s transporter has been jury-rigged to sustain two life signals within its pattern buffer indefinitely, though one has degraded too far to be recovered. La Forge reverses the process and restores the remaining life form, which turns out to be former Starfleet officer Captain Montgomery ScottOriginally, some envisioned a Dyson sphere as an artificial hollow sphere of matter around a star, and Dyson did originally use the word shell. But Dyson didn’t picture the energy-collectors in a solid shell. From an engineering perspective, a Dyson Sphere sounds pretty wild. And it is: As an immense, hollow ball, the structure is impossible. "An actual sphere around the sun is completely impractical . Another problem: The Sphere would not gravitationally bind to its star in a stable fashion. This is perhaps counterintuitive; you might think that a perfect sphere around a star would be stable. But if any part of the sphere were nudged closer to the star—say, by a meteor strike—then that part would be pulled preferentially toward the star, creating instability.

So what "really" is KIC 8462852 ?

My Possible explanation of the
KIC 8462852 phenomenon .
This is a artists rendition to
the object I believe is being
called a "Dyson" sphere.
KIC 8462852 is a  F-type main-sequence star located in the constellation Cygnus approximately 454 parsecs (1,480 ly) from Earth. In September 2015, several astronomers published a paper, as part of the Planet Hunters project, analyzing the unusual light fluctuations of the star as measured by the Kepler space telescope, which observes changes in the brightness of distant orbiting stars in order to detect exoplanetsKIC 8462852 is likely just a pair of eclipsing binaries stars in a very eccentric orbit. In the original article they assume these dips are a periodic, Another possibility is the self-emission of disk material from the star itself, as in the case of Be-stars. Be stars are rapidly rotating (almost near breakup) stars that are usually of spectral class O and B, but sometimes A, and exhibit irregular episodic outbursts. Usually these outbursts are in emission, but in some cases it can also result in dimming (see Hubert & Floquet 1998). Be stars also often exhibit quasi-periodic oscillations in the range of ∼ 0.5−1.5 days. This also fits the bill for what we see in the FT of KIC 8462852 (§ 2.1). It has been hypothesized (e.g., Rappaport & van den Heuvel 1982) that most, if not all, Be stars
Another artist concept that matches
KIC 8462852
have a binary companion which originally transferred mass to the current Be star to spin it up to near breakup (the remnant of that star is sometimes found to be a neutron star). The periods of these binaries range from a couple of weeks to thousands of days (perhaps longer). If KIC 8462852 is a Be star, we would get an unprecedented look into the inner disk behavior, and that in fact might explain the broad peak in the FT at frequencies just below the 0.88 d periodicity. This could be ejected material in a so-called “excretion disk” that is moving outward but with roughly Keplerian velocity. The lack of observed IR excess does not support the existence of an excretion disk. There is also an absence of Hα emission in the star’s spectrum, however, as noted above, Be star Hα emission is known to be variable and turn off and on with timescales from days to years. However, the temperature of KIC 8462852, Teff = 6750 K, is too cool to be a Be star. It is also unlikely to have been spun-up by a close donor star because an RV shift is absent between our two spectra. This likely rules out most remnant stars of a progenitor donor, but not necessarily a progenitor in a very wide orbit where mass transfer occurred while the companion progenitor was a giant. It is also worth noting that the imaged companion star. 
l armchair astronomer on you but there is a section in the paper that mentions the possibility of a companion. In the into to the paper they say:"We discover a wide M-dwarf companion to the system and argue that with the data sets we have in-hand, we can exclude the presence of an additional gravitationally bound companion nearby."The section where they actually discuss that is pretty dense beyond my armchair astronomy knowledge but it seems convincing to me  (See : ) . THERE ARE CONVINCING CLUES that KIC 8462852 is orbited by at least 5 small sub- stars , or "brown dwarf" star which could explain the 22 % dip in KIC 8462852's light . The Answer is vary similar to this star called J1407b , The planet orbits star J1407, located approximately 434 light-years from Earth. Astronomers first identified the ring system – the first of its kind to be found outside our solar system – in 2012. A new analysis of the data, published in the Astrophysical Journal, shows that the ring system consists of more than 30 rings, each of them tens of millions of kilometers in diameter. Furthermore, the analysis found gaps in the rings, which indicate that satellites (“exomoons”) may have formed. 
One is that perhaps a wandering star pulled foreign comets into orbit around the star. Such a phenomenon is probably rare. "It's a bit of a stretch," says Andrew Siemion, a scientist with Berkeley's SETI center. The mysterious object(s) are blocking up to 20 percent of the star's light, which is much, much more than even a Jupiter-sized planet would block. Siemion and two other astronomers have suggested an alternate explanation that may be even less likely than comets, but still very intriguing: Perhaps the star's light is being blocked by huge pieces of alien architecture. It’s important to note that Tabby’s Star ie: KIC 8462852 is 1480 light years away- which means that the light that we are observing is 1480 years old. Essentially, what we see in 2015 using telescopes and radio arrays is what was happening at Tabby’s Star during 535 CE on Earth.

(***)>>What radio signals could be expected from KIC 8462852 assuming a best reasonable case scenario?  To be brief, not much.  What we should look for is even a hint of non-thermal spectrum radio noise.  A thermal noise profile would be randomly distributed.  If it is detectably nonrandom then maybe there MIGHT be/have been intelligent life behind the anomalous light curves from that star. There is reason to be optimistic.  A simple assumption is that the amount of radio noise produced by a civilization would increase with the amount of energy it has available.  With at least 22% of the output of a star at their disposal whoever could be living around KIC 8462852 could be putting out exponentially more radio noise than a civilization on our level.  The hardest part may be knowing just what we are seeing if we see it. (2)>> STAR TREK. A small footnote: The researchers estimate that a Dyson sphere surrounding a white dwarf would be roughly 10 ^6 kilometers in radius. As pointed out by an astute commentator, this puts the newly proposed Dyson sphere within an order of magnitude of the one featured in Star Trek: The Next Generation. It may be new to science, but it seems Star Trek figured this all out loooong ago. Now let’s have a care here. The paper doesn’t mention aliens, and it doesn’t even imply aliens. Not directly, at least. But the astronomers found a star so odd, with behavior so difficult to explain, that it’s clear something weird is happening there. And some of the astronomers who did the work are now looking into the idea that what they’ve found might (might!) be due to aliens. Straight away, we know we’re not dealing with a planet here. Even a Jupiter-sized planet only blocks roughly 1 percent of this kind of star’s light, and that’s about as big as a planet gets. It can’t be due to a star, either; we’d see it if it were. And the lack of a regular, repeating signal belies both of these as well. Whatever is blocking the star isbig, though, up to half the width of the star itself!
