No, there is no scientific evidence or credible calculations that support the existence of places on Earth where the moon's rotational position correlates with unusual gravitational effects, such as rivers flowing uphill or cars rolling uphill. These claims are often associated with various pseudoscientific or supernatural phenomena.
Gravity is a fundamental force that acts uniformly on all objects on Earth, regardless of the position of the moon or any other celestial body. The gravitational pull of the moon does cause tidal effects, but these are relatively small and have no significant impact on the everyday experiences of gravity on Earth.
Any claims of specific locations where gravity behaves unusually or contrary to established scientific principles are generally based on optical illusions, magnetic anomalies, or misinterpretations of natural phenomena. They are not supported by scientific research or calculations.
It's important to approach such claims critically and rely on scientific evidence and explanations when it comes to understanding the behavior of gravity and the natural world.
