The slope of gravity hills is an optical illusion, although sites are often accompanied by claims that magnetic or supernatural forces are at work. The most important factor contributing to the illusion is a completely or mostly obstructed horizon.
What is a gravity hill?
Water appearing to run uphill at Magnetic Hill in New Brunswick A gravity hill, also known as a magnetic hill, mystery hill, mystery spot, gravity road, or anti-gravity hill, is a place where the layout of the surrounding land produces an optical illusion, making a slight downhill slope appear to be an uphill slope.
What is an anti-gravity hill?
A gravity hill, also known as a magnetic hill, mystery hill, mystery spot, gravity road, or anti-gravity hill, is a place where the layout of the surrounding land produces an optical illusion, making a slight downhill slope appear to be an uphill slope. Thus, a car left out of gear will appear to be rolling uphill against gravity.
How do gravity hills form?
Thus, the explanation that gravity hills are the result of a difference of gravitational pull between the top and the bottom of the slope is perhaps not quite feasible after all. Poured water running "uphill", this photo is of a cultural heritage site in Canada.
How many gravity hills are there in the world?
There are hundreds of recognized gravity hills around the world. The slope of gravity hills is an optical illusion, although sites are often accompanied by claims that magnetic or supernatural forces are at work.
Why do cars go uphill on gravity hill?
Gravity Hills: An Optical Illusion Also known as spook hills, gravity hills are, at their core, an optical illusion. The landscape of an area can make a small downhill slope appear to be going uphill. Cars can be seen rolling uphill against the perceived gradient of the road, stunning drivers and spectators alike.
What causes Magnetic Hill?
The Magnetic Hill is an example of a gravity hill, a type of optical illusion created by rising and descending terrain. It is located at the northwestern edge (in the Magnetic Hill Area) of the city of Moncton in the Canadian province of New Brunswick.
How do things roll uphill?
Usually it is a stretch of road in a hilly area where the level horizon is obscured. Objects such as trees and walls that normally provide visual clues to the true vertical, may be leaning slightly. This creates an optical illusion, making a slight downhill look like an uphill slope. Objects may appear to roll uphill.

How does gravity hill works?
A gravity hill is a place where a slight downhill slope appears to be an uphill slope due to the layout of the surrounding land, creating the optical illusion that water flows uphill or that a car left out of gear will roll uphill.
Can a car roll uphill in neutral?
At the peak of the road, just as the pavement appears to decline, a car stopped in neutral will roll backwards uphill. Many believe it's just an optical illusion or Earth's magnetic forces at work. But, others think the cause could be more supernatural in nature.
Is there a gravity hill in England?

What is gravity hill?
Gravity hills are a type of slope where things seem to move against gravity on their own accord. For instance, if water is poured onto the surface of the hill, it would seem to move upwards, instead of in the opposite direction, as one might expect it to. Gravity hills are also known as magnetic hills and mystery hills , ...
What happens when an object is placed on a slope?
If an object, for example, a ball, is placed on a slope, it should naturally be pulled downwards by gravity. On gravity hills, the opposite appears to occur, i.e. the object appears to move upwards instead. Numerous explanations have been suggested to account for the existence of these hills. Sometimes, these are reflected in the names ...
What is the name of the chipalope in Confusion Hill?

What is the theory of gravity?
Among other effects this had on the existing body of physics knowledge, it called into question the assumption built into Newton's concept of gravity, which is that gravity in effect operated instantaneously between objects regardless of the vastness of their separation. After Einstein's calculations established that the speed of light, 3 × 10 8 m/s or about 186,000 miles per second, placed an upper bound on how quickly anything could be propagated through space, Newton's ideas suddenly looked vulnerable, at least in certain instances. In other words, while Newtonian gravitational theory continued to perform admirably in almost all imaginable contexts, it was clearly not a universally true description of gravity.
How does gravity affect the attraction between objects?
One way to think of the gravitational attraction between objects, expressed by the late theoretical physicist Jacob Bekenstein in an essay for CalTech, is as "long range forces that electrically neutral bodies exert on one another because of their matter content." That is, while objects may experience a force as a result of differences in electrostatic charge, gravity instead results in a force owing to sheer mass. Technically, you and the computer, phone or tablet you're reading this on exert gravitational forces on each other, but you and and your Internet-enabled device are so small that this force is virtually undetectable. Obviously, for objects on the scale of planets, stars, whole galaxies and even clusters of galaxies, it is a different story.
What dimension did Einstein propose?
But Einstein had thus transformed gravitational theory from something rooted purely in physical forces into a more geometry-based theory: It proposed a de facto fourth dimension, time, to accompany the three spatial dimensions that were already familiar.
What objects were physically bound to one another?
They discerned that faraway objects such as planets and stars (the true distances from Earth of which, of course, the observers had no way of knowing) were, in effect, physically bound to one another despite presumably having nothing like cables or ropes connecting them together.
What is gravity in science?
Most people, scientifically oriented or otherwise, have at least a vague idea that some quantity or concept called "gravity" is what keeps objects, including themselves, tethered to Earth. They understand that this is a blessing in general, but less so in certain situations – say, when perched on a tree branch and a little unsure ...
Do physicists know what causes gravity?
And in truth, physicists have little idea of what ultimately "causes" gravity, any more than they can tell any of us why the universe exists in the first place. Physicists have, however, produced equations that describe what gravity does exceptionally well, not just on Earth but throughout the cosmos.
What are gravity hills?

What does it mean when a ball rolls on a gravity hill?
A ball rolling on a gravity hill appears to stop and roll back up the hill. Without a true horizon in sight, objects such as trees and walls — which your eyes use as visual clues to determine perpendicularilty — can play tricks on you.
What could cause the laws of physics to unravel into backwards chaos?
A glitch in spacetime could cause the laws of physics to unravel into backwards chaos. An army of angry ghosts could be muscling your car to the top of the hill with nothing but their bare ghost hands. Or maybe it’s just an optical illusion.
What could break the laws of science?
There are many possible explanations for what could make an object break one of the sacred laws of science: Mysterious magnetic sources beneath the earth’s surface could be slowly pulling you towards them. A glitch in spacetime could cause the laws of physics to unravel into backwards chaos. An army of angry ghosts could be muscling your car to the top of the hill with nothing but their bare ghost hands.
