Scientists use atomic clocks to show that time moves faster at altitude, even on Earth
This is for the deep thinkers here. Think outside the box.

Scientists use atomic clocks to show that time moves faster at altitude, even on Earth

By Steve Connor, Science Editor

Albert Einstein proposed that time is a relative concept and the higher you live above sea level the faster you should age

The world's most accurate clock has neatly shown how right Albert Einstein was 100 years ago, when he proposed that time is a relative concept and the higher you live above sea level the faster you should age.

Einstein's theory of relativity states that time and space are not as constant as everyday life would suggest. He suggested that the only true constant, the speed of light, meant that time can run faster or slower depending on how high you are, and how fast you are travelling.

Now scientists have demonstrated the true nature of Einstein's theory for the first time with an incredibly accurate atomic clock that is able to keep time to within one second in about 3.7 billion years – roughly the same length of time that life has existed on Earth.

James Chin-Wen Chou and his colleagues from the US National Institute of Standards and Technology in Boulder, Colorado, found that when they monitored two such clocks positioned just a foot apart in height above sea level, they found that time really does run more quickly the higher you are – just as Einstein predicted.

"These precise clocks reveal the effects of gravitational pull, so if we position one clock closer to a planet, you also increase the gravitational pull and time actually runs slower than for another, similar clock positioned higher up,"
Dr Chou said. "No one has seen such effects before with clocks which is why we wanted to see if these effects are there. We would say our results agree with Einstein's theory – we weren't expecting any discrepancies and we didn't find any," he explained.

YVW, time is not a constant. It is affected by gravitational pulls.

if you live in the center of earth you will not age?

time stops so it can never be desrtoyed?

Is there gravity at the center of the Earth? Remember, Nasa is now inferring gravity isn't what originally assumed. Magnetics are now playing a larger part in the study of the gravity theory. 2cents and SS may be able to expound on this.

Earth's gravity, denoted by g, refers to the attractive force that the Earth exerts on objects on or near its surface. Its strength is loosely said in terms of the acceleration produced by it (accelaration due to gravity), which in SI units is measured in m/s² (metres per second per second, equivalently written as m·s−2). It has an approximate value of 9.8 m/s², which means that, ignoring air resistance, the speed of an object falling freely near the Earth's surface increases by about 9.8 metres per second every second.

There is a direct relationship between gravitational acceleration and the downwards weight force experienced by objects on Earth. This is explained at weight; see also apparent weight.

The precise strength of the Earth's gravity varies depending on location.
The nominal "average" value at the Earth's surface, known as standard gravity is, by definition, 9.80665 m/s² (32.1740 ft/s²). This quantity is denoted variously as gn, ge (though this sometimes means the normal equatorial value on Earth, 9.78033 m/s²), g0, gee, or simply g (which is also used for the variable local value). The symbol g should not be confused with G, the gravitational constant, or g, the abbreviation for gram (which is not italicized).

The change in gravitational strength per unit distance (in a given direction) is known as the gravitational gradient. In the SI system this is measured in m/s² (strength) per metre (distance), which resolves to simply s−2 (inverse seconds squared). In the cgs system, gravitational gradient is measured in eotvoses.

In this dimension, AnyTHING you observe is in the past since it takes time to travel to your eye, atomic clocks also show this, hence why time is an illusion.

What a great post, I have never thought about it that way, but that's true.
