Imagine a world whose sun is swinging like a pendulum above a flat surface. This is a sketch of the diagram.
- A complete cycle lasts twenty-four (24) hours (from an end to the other and back again to the start point).
- The pendulum deviates one degree in each cycle, so after 360 days it would finish a full rotation (a year).
- There is no other celestial body in the sky to interfere with the motion of the pendulum.
- This world is flat and yet gravity attracts objects only from top to bottom, large bodies (like the pendulum sun) can affect this gravity.*
What would be like the gravitational pull over the oceans? I assume this Sun has enough mass to affect tides just as the Moon does in real life. I have made another diagram of what I think it could be like:
Black arrows represent the direction of the pendular movement and blue arrows represent the gravitational pull.
Summing up, my question is: is this gravitational pull model plausible or am I missing something? Also, I'm not sure how would this affect winds, so if you have any idea about that feel free to comment.
I hope everything is clear, but please let me know if you need more details. Thank you.
EDIT: I haven't thought about the mass of the Sun and the distance between the pendulum and the surface, but I think these numbers may vary as long as human life on this "planet" is possible. Maybe the mass of the pendulum Sun is similar to real life Moon's, and the distance is approximately the same between Moon and Earth. But as I was saying, it's not important as long as life is possible.
*It might be that, since gravity works in an unidirectional way (from top to bottom), the pendular Sun does not affect tides at all...?
