Gravity hills, also known as magnetic hills or mystery hills, are areas where the layout of the land creates the illusion that objects, such as cars, are rolling uphill instead of downhill.
This is because the slope of the land appears to be uphill, but in reality, it is actually downhill.

How does the Gravity Hill Illusion work?
Gravity hills are typically found in areas with a pronounced slope, where the horizon is obscured by a rise in the land, trees, or other obstacles. This can create the illusion that objects on the slope are rolling against gravity, when in reality, they are following the natural slope of the land.
The illusion of a gravity hill is created by the distorted perception of the landscape caused by the slope of the land and the position of surrounding objects. It is a fascinating optical illusion that has been the subject of many myths and legends. Some people attribute the illusion to supernatural forces or mysterious magnetic fields, but it can be easily explained by the science of visual perception.
Gravity hills work through the distorted perception of the landscape caused by the slope of the land and the position of surrounding objects. The illusion is created when the slope of the land appears to be uphill, but in reality, it is actually downhill.
This optical illusion occurs when the horizon is obscured by a rise in the land, trees, or other obstacles. This can create the illusion that objects on the slope are rolling against gravity, when in reality, they are following the natural slope of the land. The illusion can be so convincing that it appears as though a car left in neutral on the slope will roll uphill, even though it is actually rolling downhill.
The exact mechanism that causes the illusion of a gravity hill is not fully understood, but it is believed to involve the distorted perception of the slope of the land and the position of surrounding objects, as well as the position of the observer. The phenomenon is an example of how our visual perception can be easily misled, and it highlights the importance of using scientific measurements and observations to accurately understand the world around us.

Illusions like the Gravity Hill Illusion
A gravity hill is a type of optical illusion caused by the distorted perception of the landscape. It is a phenomenon where the slope of the land appears to be uphill, but in reality, it is actually downhill, creating the illusion that objects, such as cars, are rolling uphill instead of downhill.
This illusion is created by the slope of the land and the position of surrounding objects, such as trees or hills, that obscure the horizon. The distorted perception of the landscape can be so convincing that it appears as though a car left in neutral on the slope will roll uphill, even though it is actually rolling downhill.

Some similar illusions are as follows:
The Ponzo illusion is a type of visual illusion in which a pair of parallel lines, or a horizontal bar, appear to be of different lengths based on the presence of a converging or diverging set of lines, often resembling the converging parallel lines of a road or railway track, placed above and below them.
Forced perspective is a technique used in photography, architecture, and other visual arts to manipulate the perception of the size and distance of objects.
It creates the illusion of a larger or smaller object, or of one that is closer or farther away, by carefully controlling the angles, proportions, and placement of objects in the scene.
The Ebbinghaus illusion: This illusion is similar to the Delboeuf illusion but in this case the central circle appears larger when surrounded by smaller circles and smaller when surrounded by larger circles.
The Delboeuf illusion is a perceptual illusion in which the perceived size of a circle is affected by the size of the surrounding circles.
The Occlusion illusion is a visual illusion where an object that is partially obscured by another object appears to be farther away than it actually is. This illusion is caused by the brain’s interpretation of the relative depth of the objects based on their relative size and position. This phenomenon is based on the visual cues that the brain uses to perceive depth, such as relative size, position, and overlap.
The Müller-Lyer illusion is a classic example of size-contrast illusion, in which two lines of equal length appear to be different due to the presence of arrowheads or fins at the end of the lines.
The moon illusions involves the perception of the Moon appearing larger when it is near the horizon compared to when it is high in the sky.
The Kanizsa triangle is a visual illusion that was first described by the Italian psychologist Gaetano Kanizsa in 1955. The illusion consists of a white equilateral triangle that appears to be surrounded by three Pac-Man-like shapes, which are black and have white crescents facing inwards.
All these illusions demonstrate that the perceived size of an object can be influenced by the context in which it is presented, and that the brain uses the size of the surrounding objects as a reference point to judge the size of the central object.
Discovery of the Gravity Hill Illusion
The discovery of gravity hills, or magnetic hills, is not credited to a specific person as it is a natural phenomenon that has been observed and documented by various cultures for many years.
People have been aware of the optical illusion created by gravity hills for a long time and have attributed the phenomenon to a variety of causes, including supernatural forces and mysterious magnetic fields.
In recent times, scientists and geographers have studied the phenomenon and explained it through the science of visual perception and the distorted perception of the landscape caused by the slope of the land and the position of surrounding objects.
However, there is no specific individual credited with discovering gravity hills.
