The real giveaway for me is the area of black underneath the engine.
The "hole" in the front of the engine is black because light is not reflected out of it. If this were a real picture, then the black hole would not produce a black reflection, but the image of water under ambient light, similar to other parts of the water.
The black reflection of the black hole appears because the computer program has, in it's own rather dumb style, just taken the colour values from the area above.
But I still think it is fun!
