The hills that defy gravity: the explanation of a mysterious phenomenon

the mysterious gravitational hills or magnetic hills, represent one of the strangest natural phenomena that exist. Therefore, for many they do not find an explanation, scientists have revealed their explanation.

They are not exclusive to any specific place in the world, as these captivating locations exist in the US, UK, Australia, Brazil or Italy, to name countries on different continents.

In these hills one can be amazed to see how the cars circulate on them they seem to go uphill as riders struggle on an apparent descent.

The first thing that scientists clarify is that it is, neither more nor less, a work optical illusion almost impossible to believepoint from Scientific alarm.

“The embankment is inclined so that it looks like it’s going uphill,” explained the physicist Brock Weissof Pennsylvania State University.

And he adds: “In fact, you are going downhill, even if your brain gives you the impression that you are going uphill.”

the British psychologist macintosh robberyfrom the University of Edinburgh, delves into how our eyes deceive us every time we come across one of these gravity hills.

And it raises, perhaps, the key point of the phenomenon: lose sight of the horizon: “We are inside a sloping landmass,” explains in a video a Science Channel.

“The whole landscape slopes like this, and the road slopes in the same direction, but to a lesser extent, therefore relative slope appears to go in the opposite direction“, he says with the idea of ​​clarifying the situation.

Another 2003 study suggests that the absence of a horizon helps vary perspective on these gravity hills by recreating a series of places of “anti-gravity”, divulges 20Minuti.

The researchers, from the universities of Padua and Pavia, Italy, determined that with no real horizon in sight, landmarks such as trees or signs play a trick on the human brain.

“The perceived slope depends on the height of the visible horizon. The slope of the surface tends to be underestimated with respect to the horizontal plane”, begins the research published in Psychological Science.

And he expands: “When it is preceded, followed or flanked by a steep downhill slope, a slightly downhill section is perceived as uphill”.

For those who prefer to be amazed live, they offer two cases from the hills where you can better perceive this incredible phenomenon: hill of confusion, in California, United States; Y Magnetic Hillin Canada.
