Tabby's star - source of some alien civilization's daily power or something about which we don't know yet?

If you already don't know, I'm talking about a star known as Tabby's star or Boyajian's star which goes by the code name KIC 8462852 and is approximately 1,280 light years away from us. ## What's so special about it? The fact that unlike any other well-known star, its light is fluctuating abnormally or you can say unusually. This unusual light fluctuation was discovered by citizens scientists as a part of the Planet Hunters project and in September 2015 an article was published on it describing the data and possible interpretations. It dimmed in ways nobody could really explain and among all the interpretations one was that some alien civilization has build a mega structure to draw power from this star and as they draw the power the light decreases. Intriguing, isn't it? In 2011, its light was dimmed by 15%. Here's a graph which demonstrates this drop: ## That's almost impossible (with respect to what we've known yet). A sudden drop

Is it possible for aliens living millions of light years away to see the dinosaurs walking alive on Earth?

This is an amazing theory and idea which was put forward by an astrophysicist named Matt on his website QuarksandCoffee.com It is a common and well established theory that light takes time to travel. When we see the Sun, we are actually seeing it as it was 8 minutes ago and not in it's present form. So, if for some reason, the Sun gets disappeared at this moment, nobody here on Earth would be able to figure this out for another 8 minutes. ## So, as the sun is just 149.6 million km (0.00001581 light years) away from us, it takes light 8 minutes to reach us and we see the Sun as it was before 8 minutes and not as it currently is. Similarly, what if an alien civilization living millions of light years or let's say 65 million light years away (as dinosaurs were present on Earth at that time) take out their telescopes and point it towards Earth? What would they see? Would they be able to see dinosaurs walking around? Interesting, isn't it? ## Well, if we ta
