Time and Relativity

The fact that the clock on the second floor is futher from the Earth’s center of gravity means that the clock on the second floor will move faster. The same principle works with anything. If a human stood on the second floor of a house he would age faster than when he stood on the first floor of his house because he would be further from the Earth’s center of gravity. The person would also weigh less on the second floor of his house than the first floor of his house. The further a person goes above the surface of the Earth the less he weighs and the faster he ages. This works on different planets and stars too. If you go underground like in a Subway you will age slower and you will weigh more. If you go to the mountains or on an airplane you will weigh less and age faster. When you go to space you age much more rapidly and are much lighter than when you are on Earth. I just don’t know how much of a difference there is in weight and age acceleration for every feet, or mile you go above the Earth’s surface. Does anybody know a certain equation that I could use to find out how much time accelerates for the distance you are above the Earth’s surface?
