Sally and her brother on earth are both ten earth revolutions older by the time Sally gets back to earth, correct?

Clocks run a bit faster in the attic than in the basement, which is closer to the center of Earth and therefore deeper down in a gravitational field. Similarly, clocks run faster in space than on the ground.
so my old timex is what determines the global "time" ?

gimme a break. time is an abstract concept, and to think the just by taking a timex to outter space (or in a plane for that matter) makes time pass faster? how does the watch know to run faster? the little gears go "whoa we need to move faster now"?

even with an atomic clock, the little electrons go "move faster dude"

even if in some way they do talk to each other and move faster, that would have no effect on the passage of an abstract concept.

whoever wrote that is absurd.
I don't know what to put here yet.

Time is not an abstract concept: it's a relative concept, that's the whole point of this thread.

i love this stuff!   personally 10 earth years in space (@high velocity) should = 10 earth years here (as far as aging is concernd)

im no physic guy but, if said sally had the scope and wa traveling at such  a velocity of near/at or beyond light speed (wise guys keep an open mind) woudnt the earth slow down or go in a backward direction as she traveled ? the light from the earth the she see's is gonna take longer for her to see it and the father she goes and faster she goes it seems to me logical that the earth from her prosective would stop and rewind, if she passed the SOL (Speed Of Light)

this is a nice read for us laymans as an idea to supass the speed of light.................the old German Jew dont believe it could have been done but new ideas spark thought............http://www.hbccufo.org/modules.php?name=News&file=article&sid=1042

Nuke and Boxboy:

Time is not consistent in the universe, it depends on the speed you are going and the amount of gravity you are experiencing.

Both effects are proven in many experiments.  

For example it hs been proven that time runs at different speeds when two identical nuclear clkocks are seperated, one being left on earth surface and the other flown on a jet. The one on a jet runs slower because of the jets speed. The clocks are accurate enough to record the difference.
 
Nuclear clocks work by "timing" the decay of radioactive materials. The decay rate (in earth time) is known for such materials so counting the decay gives the most accurate time measurments possible.  

Now here's the kicker.  The clock on the jet registered a slower time because the rate of decay changed due to the time changing effects of speed. Its actually decaying slower, in other words its aging slower than the radioactive material left on earth.

Thats 100% like the twin paradox, its a proven effect. This also mrans time travel into the future is a proven effect.

As for gravity.  Gravity slows time. It has been proven. A clock at ground level runs slower than a clock 100 ffet higher.

Global Positioning Sysatem GPS actually takes this into account. If the clocks in the satelites in space were not adjusted for thie effect GPC would be totally innacurate.

Pretty wild stuff, speed and gravity have a phyisical real world effect on time.

Hmmm... the clocks in the GPS satellites are not adjusted. If so, we wouldn't have to account for the error that increases at each leap year. GPS is about 14 seconds off of UTC today.

Time simply goes slower at higher speed and higher gravity.

It's aproven phyisical fact.

The reason your timex would speed up or slow down is because it reports to yoiu the amount of time that is going on. The clock does not create time, it maesures it.  Its like a water flow gague, it doesnt create the water flowing throughh it, it just says how much is flowing. And the flow rate is time.

TIME IS NOT AN ABSTRACT CONCEPT

If you think it is, then do explain how time is affected by gravity?

Because it's proven fcat that clocks run slower in high gravity.

How is an " abstract concept" effected by a physical force such as gravity.

All I'm saying is that GPS does take into effect the time difference of runjing at reduced gravity.

Thanks Grun, I have been aware of the atomic clock experiment since I was a very young kid. It's a proven fact, you are right.

Gotcha... the clocks are set to account for this phenomena before they are launched. I'm with ya.

Yep Nuke it's very cool stuff.  

For more cool stuff see these free internet videos, allready posted here, but worth showing again:
