I wonder how the progress of science and physics and religion would have changed if we had a sun and black hole pair, but otherwise the same earth.
As a matter of fact, many ancient civilizations have “Gods” for the point where moon’s orbit intersects with Earth. https://en.wikipedia.org/wiki/Lunar_node
In Hindu mythology - we have two “shadow planets” and gods called Rahu and Ketu https://en.wikipedia.org/wiki/Rahu these points are no real planets or moons - but are given the same status.
