Why was only KIC 8462852 affected? Your hypothesis is a non-starter.

Hey all the space stuff--we're kidding.
We all know the world's flat right guys? (you can call off the battle fleet now.)
https://en.wikipedia.org/wiki/Cygnus_(constellation)
A list of potential causes effecting KIC 8462852:
1. Cygnus X-1 : home to a binary system containing a SuperGiant and an unseen massive companion that was widely held to be a black hole.
https://en.wikipedia.org/wiki/Cygnus_X-1
Cygnus X-1 was the subject of a friendly scientific wager between physicists Stephen Hawking and Kip Thorne in 1975, with Hawking betting that it was not a black hole. He conceded the bet in 1990 after observational data had strengthened the case that there was indeed a black hole in the system.
The black hole could be siphoning off small amounts of surface matter from KIC 8462 depending on how close KIC 8462 is to Cygnus X-1. After locating and comparing the distances between KIC 8462 and Cygnus X-1 the distance is great as well as other stars being the direct path of the black hole that would also be affected and would have a decrease in their light curve as well.
2. In addition, most of the eastern part of Cygnus is dominated by the Hercules–Corona Borealis Great Wall, a giant galaxy filament that is the largest known structure in the observable universe; covering most of the northern sky.
Galaxy Filament - https://en.wikipedia.org/wiki/Galaxy_filament
In the standard model of the evolution of the universe, galactic filaments form along and follow web-like strings of dark matter.[4] It is thought that this dark matter dictates the structure of the Universe on the grandest of scales. Dark matter gravitationally attracts baryonic matter, and it is this "normal" matter that astronomers see forming long, thin walls of super-galactic clusters.
KIC 8462852 in Cygnus[22] is located roughly halfway between the major visually apparent bright stars Deneb (α Cyg, α Cygni, Alpha Cygni) and Delta Cygni (δ Cyg, δ Cygni) to the eye as part of the Northern Cross.[23] KIC 8462852 is situated south ofOmicron¹ Cygni (ο¹ Cygni, 31 Cygni), and northeast of the star cluster NGC 6866.[23]While only a few arcminutes away from the cluster, it is unrelated and closer to the Sun than it is to the star cluster.
I would have to say that the reason for the decrease in the light of KIC 8462852 would be because the sun is being veiled by Dark Matter.

Surely all these objects are sitting at the same distance on the celestial sphere, which is only 20,110 Earth radii away. Well, that's what Al-Farghani reckons, although Al-Battani estimates 19,000 Earth radii. I think we should base all our discussion on the knowledge of the cosmos in the 10th century.

Could fluctuations in space-time at the Quantum level be responsible for the decrease in light of KIC 8462?
Another question I had about stars is this. A few weeks ago I was looking at the stars on clear crisp morning at around 3:30 am. One star seemed to flicker very happy oddly as did another to the left. The stars in between however were not flickering the same way.
The flicker looked like the Iights of an airplane flickering but once I realized the way objects were not moving that they were stars.
Here is video of another star that flickered in the same manner over Canada.
What the heck is this flickering blue, red, white…:
I was reading about why stars twinkle in this article.
https://astrobob.areavoices.com/2011/09/04/why-stars-twinkle-and-sputter-in-color/
Could it possible that a thick atmosphere is passing in front of KIC 8462?
Possibly oxygen isotopes given off by another star or even the fact that something might have happened to Super Gas Giant that caused the gas giant to lose its gas that is now passing between KIC 8462 and Kepler?

That's why we need additional spectroscopic observations of the dimming to determine whether the transiting matter is opaque or translucent, and if translucent, determine its composition. The KST instruments do not provide that information.
The flickering or scintillation of stars can vary across the night sky because the amount of air in the line of sight varies and contains air in turbulent motion, downdrafts, updrafts, water vapour, ice crystals and other matter. KST, of course, is well outside the atmosphere and none of the other stars examined have light curves at all similar to KIC 8462852.

There are a lot of stars in the same approximate direction as KIC 8462852. See, for example:

It doesn't mean that the stars in the same field of view are at the same distance, of course. By the way, your chart isn't very clear on the position of KIC 8462852 relative to the open cluster NGC 6866. Here's a couple of links that are clearer:

Oh, and by the way, if there were a very large black hole present, one might expect to see gravitational lensing of light from background stars in the Milky Way. However, a black hole of, let's say, ten solar masses would have a Schwarzschild radius (r = 2GM/c^2) of only 30 km and would be difficult to detect by gravitational lensing -- it would more likely be detected by its gravitational pull on nearly objects or by radiation emitted from its accretion disc.

Yeah, another mysterious light curve that isn't readily explainable. However, the estimated age of this star (< 11 My) seems to imply that the cause might be an edge-on, clumpy protoplanetary disc.
The researchers report that over 78.8 days of observations, EPIC 204278916 displayed irregular dimming of up to 65 percent for around 25 consecutive days.
There either has to be an alien mega-structure orbiting EPIC 916 or there is a black hole close by that has not been observed.
I doubt a swarm of comets would block out 65% of EPIC 916's light for 25 consecutive days.
It might sound very odd but what about several Huge Gas Giants orbiting very closely to EPIC 916 and to each other where their planetary rings might be overlapping each other causing a much larger area to be covered causing less light to be viewed?

You forgot to mention the mutant star goat.

Or . . . or, developing, or partial accretion disk (or nivanringdysonswarmblackhole).
Or . . . or, developing, or partial accretion disk (or nivanringdysonswarmblackhole).
A black hole would be detectable by its gravitational effects and by X-rays emitted by matter falling on to its accretion disc. Also, if the dimming is due to orbiting matter, it should recur at regular intervals. All this guy has done is contrive something that mimics the dimming. For example, he adjusts the coefficient φ to be different on the left and right sides of the structure without offering a physical explanation. The guy may be a good software programmer but he's not impressive as an astronomer/physicist/astrophysicist. I doubt this "paper" would pass peer review.

This image shows a comet breaking apart. Would it be possible for a comet to constantly break apart to create a continued decrease in light from KIC 8462852?

It's a stretch to make comet breakup or multiple comet breakups produce transits that match the light curve dimming, as mentioned in the link provided by @psCargile.
It needs a lot more data gathered over more wavelengths and for a lot longer than one or two earth years.
I looked through Jason Wright's blog, and watched a presentation of his, odd indeed. Once you rule out what it's not, you're not left with much. Unique stellar process? Dark matter? Stardam?
Dark Matter is another exotic choice. Dark Matter is still elusive and is not fully understood.
http://www.sciencealert.com/researchers-just-found-a-second-dyson-sphere-star - EPIC 916
Two stars experiencing dramatic light curves.
I think that by connecting KIC 8462 and EPIC 916 together in a three dimensional computer animation with a line and then map how the line between the two stars fluctuates, twists, curves, ebbs, etc. as both stars move through space. We might have a better understanding of what is taking place with both stars and possibly between both stars as the fluctuations in the line curving and twisting between both stars might unveil hidden interactions paralleling the line fluctuations as both stars complete their movements through space.
What is the distance between EPIC 916 and KIC 8462? Is the distance observable with the naked eye or is a telescope required?
I am going to have to say that another star with light curve fluctuations comparable to EPIC and KIC is present to create the "Three-Holed Wonder" Constellation.
So far we have two stars that have light curve fluctuations:
KIC - up to 22%
EPIC - up to 65%
Based on the numerical curve between the two stars there should be other stars that have light curve fluctuations taking place before and between the 22% and 65% range as well as above the 65% to the 99% range of light curve fluctuations that might reveal an influence of Dark Matter.
