I can’t believe that all of you are missing the whole point of this fantastic image! But then, I am an expert UFOlogist and the rest of you are not. This is obviously the work of at least a Type II civilization that is capable of harnessing the energy of multiple stars. The diagram at the top is clearly a schematic showing a gigantic black hole (on the right) sucking a stream of energetic matter and photons from a triple star system on the left. The distortion of spacetime caused by the tremendous gravitational force of the black hole has bent the stream of matter into the rainbow-shaped form meant to represent an accretion disk, and the multiple colours are meant to represent the intense broad-spectrum radio emissions due to the highly energetic particles streaming through it. The strange device on the left is obviously the energy generator itself, seen to be connected into the matter stream, and probably capable of producing the energy of a thousand suns.
The rest of this extraordinary image, below the accretion disk and energy generator, is probably a schematic intended to show how the energy system works. Sadly, this civilization is millions of years more technologically advanced than we are, and it is doubtful that we’ll ever understand what they’re trying to tell us. We can only hope, should they visit us again, that they are kind and benevolent beings who will wield their coloured chalk in peace. I am trying not to think about that strange image on the lower left, which looks disturbingly like a planet exploding. I would suggest that if we come across any strange-looking creatures with an unusual number of limbs and antennae coming out of their foreheads, we should be extra nice to them, just in case. If they express a wish to take you to their saucer and examine you, just go along with it. You’re probably overdue for a colonoscopy anyway.
