Some new observations surrounding Boyajian’s star, or KIC 8462852, might provide the information we need to know with certainty whether Aliens are involved or not.
Boyajian’s Star, previously referred to as Tabby’s star, is named after the astrophysicist who first studied the star’s inexplicable behavior. Boyajian’s star is a bit larger than Earth’s Sun, and the star is roughly 1,300 light-years away.
And the star displays behavior that scientists just can’t figure out. The star’s behavior is actually the most unusual dimming of a star ever observed—its brightness dips in erratic and unpredictable ways and the dimming is much too substantial to be caused by an orbiting planet, because even planets as big as the biggest ones in our solar system would only make a tiny blip in the brightness of Boyajian’s star.
Plus, if it were a planet, we should be seeing the same dip in brightness at regular intervals as the planet runs rings around that star…but no.
And it is this lack of convincing explanation that led to the idea of an energy-generating alien technology, like a Dyson sphere, being behind Boyajian’s star’s dimming.
And while it might be tempting to think the unpredictable behavior of Boyajian’s star is due to some sort of alien megastructure—Columbia University recently provided a new model that might give us an answer that does not rely on an alien civilization, and the theory has to do with a stolen exomoon.

There Are Gravity Pulses Hiding in the Universe’s Most MASSIVE Stars
Orphaned exomoons: Tidal detachment and evaporation following an exoplanet–star collision
“Gravitational perturbations on an exoplanet from a massive outer body, such as the Kozai–Lidov mechanism, can pump the exoplanet’s eccentricity up to values that will destroy it via a collision or strong interaction with its parent star.”
Astronomers Have Found Another 21 Stars Dimming as Erratically as Tabby’s Star
“When KIC 8462852 – affectionately known as Tabby’s Star – arrived on the scene in 2015, it made one heck of a bang. We’d never seen a star like it before.”
Planet Hunters IX. KIC 8462852 – where’s the flux?
“Over the duration of the Kepler mission, KIC 8462852 was observed to undergo irregularly shaped, aperiodic dips in flux of up to ∼20 per cent.”
