Gravity Hill: Explained

Many people and organizations have experimented to try and find out what makes your vehicle roll up the gravity hills and they have all seemed to come to the same conclusion. It is the logical explanation that I also believe to be true.

    Physicist Brock Wiess for Science Daily looked into the gravity hills. He concluded that the hills are just an illusion, and when surveyed, the end -or top- of the hill is actually lower in elevation than the start -the bottom- (The Mysterious Gravity Hill). "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" 
(The Mysterious Gravity Hill). These are found all over the world and I believe that they are too common to all be caused by the same paranormal phenomena.

Here is a video of  a reporter and Brock Wiess Explaining this phenomenon:

This next video is another investigation, but it is longer and more in depth showing the actual investigation instead of just talking about the results.

The actual main experiments can be found from 1:45 to 6:18.

    In any investigation (as previously displayed) of a gravity hill, there was always a perfectly logical explanation for rolling "up hill": it is an optical illusion. The mind is a powerful thing, but it can be fooled in many ways as well. I understand that it is an experience to go see for yourself and that it can seem really cool even if you know the 'secret' behind it. I think it is all good fun that can still be enjoyed after the truth is revealed. It is just an optical illusion to thrill the senses and make the impossible seem to be possible!

    "An optical illusion does not generally exist physically but it is difficult in some cases to explain the cause. Certainly there are many cases of errors of judgment" (Optical Illusions are Everywhere).

    More Simply: "Optical illusions, more appropriately known as visual illusions, involves visual deception. Due to the arrangement of images, effect of colors, impact of light source or other variable, a wide range of misleading visual effects can be seen" (Kendra).

    Although it is quite fun to fantasize about possible explanations as to why cars seems to drift uphill, the mind is just easily tricked into believing it is a hill when in fact it is a slight downhill. Even with that knowledge it is still a very odd experience.
