What is Gravity?
Isaac Newton presented to the world, his law of universal gravitation in the 17th century, without actually being able to explain how and why this force operates. Later came Albert Einstein, who, in 1917 attempted to explain this phenomenon by proposing his theory of general relativity. This theory attributes the force of gravity as “the unseen warping of the fabric of space-time, caused by the presence of mass.
In other words, Einstein sees Space as a sheet, the sun (the cause of the warping or curve) as a basket ball, and the earth as a tennis ball. First, imagine that the sheet is spread out tightly. Now, place the basket ball (the sun) into the middle of the sheet. This would naturally cause a slight dent. Then, put the tennis ball on the edge of the sheet and what happens?
It rolls towards the basket ball!
What does this have to do with my article? Probably nothing more than to demonstrate my satisfaction at being able to explain one of Einstein's theories.
Anti-Gravity Hills
Anti-gravity hills seem to defy all rules of gravity. In some cases, water is reported to have rolled up-hill. Generally, on hills like these all over the world, people are intrigued enough to stop and put their cars in neutral, just to watch them spookily roll up the hill.
All this is fascinating stuff, but at the cost of being a spoil sport, I have to mention here that some scientists have explained this seemingly spooky anti-gravitational "pull" as an optical illusion. They say that in areas such as these, the horizon has been obstructed partially or completely, which results in the human eye seeing an upward slope for a downward one.
Here are some pictures for you to make up your own minds.

The Hummingbird Highway in Belize, is one of the four major highways in that country. People here, even the locals, stop their cars and put them in nuetral so that they can watch them roll up-hill.

These above two pictures are of a Magnetic hill in Los Banos, which is south of Calamba, heading away from Manila in the Philippines. Notice that the water on the surface of the road, seems to be rolling up-hill.

Spook Hill, Lake Wales in Florida is a popular destination for locals and tourists alike. As you can see, tourists are encouraged to stop and let their cars roll up-hill.

Mt. Yashmina, Takumatsu City, Japan. The incline you see, is actually where the cars stop and roll up instead of down.
Gravity is not the same all across the earth. Apparently, there are highs and lows where the gravitational field of the earth is either strong or weak. This could mean that many people aren't as heavy as they think they are (which is good news for those travelling to Asia, as it is reported that there are several low spots around India).
Joking aside, this phenomenon, has not yet been explained in its entirety, but whatever you believe, this is just one of the many spooky occurrences on our planet, for which we don't have all the answers.
