The popular story of Sir Isaac Newton states that he was sitting under an apple tree when an apple fell on his head, and he pondered for a bit before he thought of the universal law of gravitation. According to the universal law of gravitation, any two bodies attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. But is it true that there are places on the Earth, where this law doesn't apply? What's going on here?
Gravity hills.. all places that are optical illusions. The terrain and environment creates the illusion, making it appear to contradict gravity.. when it never actually does. As for the guy asking why people feel weird or why animals are scared of said places.. it is because our brains evolved to take in our surroundings how we normally do. So when you go somewhere where all the trees are slanted one way with the ground slanted the other way.. your brain is going to try (and fail) to make sense of it. It is known that optical illusions can trick and stress your brain out. I remember when those magic eye illusions were a fad.. they can really make your brain feel weird and woozy. To an animal, that is going to freak them out.
