Gravity Hill is a popular phenomenon where a slight downhill slope appears to be an uphill slope due to the surrounding landscape. When vehicles are parked in neutral, they seem to roll uphill, creating an optical illusion that confuses many visitors. This unusual effect is caused by the horizon and terrain, which trick the brain into misinterpreting the slope. Many locations around the world claim to be Gravity Hill sites, attracting tourists and curious explorers. These places often have local legends or stories associated with them, adding to their allure. Despite the mystery, the science behind the phenomenon is well understood, rooted in the principles of perspective and visual perception.
