There’s a star called KIC 8462852 ( Tabby’s Star ) that the light from the star isn’t doing what a normal star of that age is supposed to be doing. It’s blinking, dipping and randomly getting brighter and dimmer. Over the past 100 years (data was found going back to the year 1890) showing the star dimming over time. As if something was slowly over the course of the past 100 some years blocking it’s light.
Due for a lack of reasonable explanation gives us the **remote** possibility of what appears to be a partially constructed Dyson Sphere or Dyson Swarm.
Several competing theories on why this is happening, with the primary one being a huge mass of comets blocking the star. This fell apart however due to the historical and recent data suggested it would need 648,000 giant state sized comets orbiting the star to cause these dips over the course of the 100 year period. This is something that is deemed impossible. The next possible solution would be a Dyson sphere or Swarm. A hypothetical megastructure that completely or partially encompasses a star and hence captures most of its power output (source Wikipedia).
The reason for someone to build such as massive structure would be to capture a huge portion of the output of a star. The energy production from a project like this would be massive.
It would be interesting to say the least that our first view of an extraterrestrial would be the construction of a type II Civilization. If that was the case (which is unlikely) it means that this object that we are seeing is at 1,500 light-years away means that this was built at least 1,500 years ago, for all we know we’re looking at ruins of a civilization a million years old or a bunch of dirty comets that just happened to make it look like it was artificially built.
Assume against all probability assume that this really is a Dyson Sphere. We are looking at a Dyson Sphere orbiting their star in the year 515 AD. I don’t know, I doubt we savages would have anything in common with them. To put something in Solar orbit like that, you’d assume it wasn’t put up overnight. This structure most likely was built (if it was built in the first place) at least thousands of years ago.
This really is a mystery. If this proves to be true (and honestly I’m not sure if it will ever be proven in our lifetime) it would be an amazing thing to know we are not alone in the universe.
Most likely the universe is teeming with life. We already found evidence of ancient microbes from the planet next door (Mars, image below)
But the image above most likely isn’t like whatever built that Dyson Sphere .. .again if it’s proven to be true. That is a huge jump from some random bacteria like alien compared to the engineering skills needed to build such a massive structure orbiting a star.
Who knows what is going on up there, but whatever it is it’s amazing.
