Wadi e Jin, Cars rolling upward on downward slopes everything Explained. . .


The Story of Prpohet Muhammad (PBUH) related to wadi-e-jin is true but this is not that the cars move upward on a downward slope or downhill because of Jinnnat.

Its Scientific Explanation is;

A gravity hill, also known as a magnetic hill (and sometimes a mystery hill or a gravity road), is a place where the layout of the surrounding land produces the optical illusion that a very slight downhill slope appears to be an uphill slope. Thus, a car left out of gear will appear to be rolling uphill due to gravity.
There are hundreds of gravity hill locations around the world.
In bicycle racing, such roads are known as "false flats".

The slope of gravity hills is an optical illusion, although sites are often accompanied by claims that magnetic or even supernatural forces are at work.
The most important factor contributing to the illusion is a completely or mostly obstructed horizon; without a horizon, judging the slope of a surface is difficult as a reliable reference is missing. Objects one would normally assume to be more-or-less perpendicular to the ground (such as trees) may actually be leaning, offsetting the visual reference. The illusion is similar to the well-known Ames room, in which balls can also appear to roll against gravity.



The Mysterious Gravity Hill

Physicists Show "Antigravity" Mystery Spots Are Optical Illusions

June 1, 2006
At several hilly locations around the U.S., know as "gravity hills," objects such as cars left on neutral supposedly roll uphill, driven by unknown forces and against the force of gravity. Physicists say -- and GPS measurements confirm -- that the effects are illusions caused by the landscape. The position of trees and slopes of nearby scenery, or a curvy horizon line, can blend to trick the eye so that what looks uphill is actually downhill.


BACKGROUND: Visit Gravity Hill in New Paris, Pa., and you will see cars that appear to roll uphill, while water flows the wrong way. Don't worry -- gravity hasn't really gone haywire. It's simply an optical illusion, one that can be found in hundreds of similar areas around the world.

HOW IT WORKS: The human eye and brain can be easily fooled into thinking the laws of physics are being defied -- but it's all distortions in perspective and odd angles. What such "mystery sites" all have in common is a completely or mostly obstructed horizon, which makes it difficult for human beings to judge the slope of a surface. They lack a reliable reference point, and this can override the body's sense of balance, especially if the slope is shallow. In the case of Gravity Hill, the layout of the surrounding landscape produces the illusion of a very slight downhill slope, when in fact it is a slight uphill slope. So a car left out of gear will appear to be rolling uphill.
WHAT IS GRAVITY? In the 17th century, Isaac Newton came up with the law of universal gravitation, but he couldn't explain the underlying mechanism behind gravity. In 1917, Albert Einstein proposed his theory of general relativity. This attributes the force of gravity to the unseen warping of the fabric of spacetime, caused by the presence of mass (or energy). The earth always travels in a straight line. The presence of the sun curves space and thus the earth appears to be moving in an elliptical orbit. Imagine a rubber sheet stretched out tightly. If a bowling ball is placed in the center, the ball's mass will cause a depression in the sheet. If you then place an apple on the edge of the sheet, it will roll down the slope towards the center. The depression can't be seen by someone looking straight down at the sheet from above, so it appears that the apple was pulled by an invisible force.

List of Gravity Hills through out the World:-
(from wikipedia)
This is a list of gravity hills and magnetic hills around the world. A gravity or magnetic hill is a place where a slight downhill slope appears to be an uphill slope due the layout of the surrounding land, creating the optical illusion that water flows uphill or a car left out of gear will roll uphill, among others. Many of these sites have no specific name and are instead often simply referred to as 'Gravity Hill' or 'Magnetic Hill'.

Mystery Spot in Santa Cruz, California
  • Placer County: Highway 20 about 4 miles west of the Interstate 80 junction. A Pacific Gas & Electric company canal crosses under the highway and appears to westbound travelers to flow uphill to the left[48]
  • Devore: On Glen Helen road pass two consecutive train tracks and end up at a stop sign. Make a U-Turn and head back towards the tracks, but stop the car at the beginning of a chain link fence on the left hand (driver) side.[49][50]
  • Whittier: Site at cemetery in Whittier, on Workman Mill Rd., near Rio Hondo Community College[51]
  • San Diego: The exit ramp in Mira Mesa/Sorrento Valley while going 805-S is a gravity hill. Testers should be cautious, considering it is a freeway exit.[52]
  • Santa Cruz: Mystery Spot at 465 Mystery Spot Road is a spot about 150 feet in diameter located in a redwood forest.[53]
  • Petaluma: (Located in Sonoma County) From US 101 Freeway, take Rohnert Park Expressway east to Petaluma Hill Road. Petaluma Hill Road south to Roberts Road. Roberts road east to Lichau Road. At an iron gate with the words, "Gracias San Antonio," is the start of the gravity hill section (on the western slope of *Sonoma Mountain near the Fairfield Osborn Preserve).[52]
  • Oak Glen: A magnetic hill is founded 10 miles or so down Oak Glen Road passed Riley's Farm. The hill is located two turns passed Riley's.

  • Mooresville: Head west out of town on High Street (2 blocks South of Main), which becomes State Road 42. Take the first right onto Keller Hill Road, and go approximately 1 mile over a few small hills. Stop at the big hill, there is a silo right before arrival at Gravity Hill. Line up the front with the large old tree on the right.[59]

  • Salt Lake City: A few blocks northeast of the Capitol building in Salt Lake City. Driving up past the capitol building, with the capitol to the driver's west, there is a small road (Bonneville Blvd.) that loops around a park in lower City Creek Canyon called Memory Grove. It appears that the car is going downhill while actually gaining in elevation from the valley floor.[83]

  • Prosser: Near a small farm on North Crosby Road, approximately 10 miles northeast of Prosser. Set vehicle into neutral at the word "start" that is written across the surface of the road and car will start rolling "uphill." [84]
