The Twin paradox (I forgot whether this is a true experiment or an assumption made by scientists) basically states that if 2 identical twins, with one launched into space, and one staying on Earth, and after the one, who was launched into space, has travelled a certain number of distance at a particularly high speed (this has to be very fast), comes back into Earth. The one who was launched into space would be younger than the one who stayed on Earth. I do not know in what regard or dimension they went about measuring the difference in age between the twins (whether it is their physical appearance or their chemical compositions that have shown the aging process).

yeah that theory is about light travel but most get it all wrong or at least understand it wrong...
here's an example ... twins are born and one is launched into space. The one launched into space travels at the speed of light going out 5 light years then returning. Amount of time that have pasted is 10 years. the twin that wnt out and came back hasn't experienced the passage of time. the one on earth is 10 years older then the twin that left.
as for how they've proven the theory is the space ship travels at around Mach 20 or so out in space. thats fast. not even close to the speed of light but fast still. they had a nuclear clock on board (you know the extremely acturate ones that use the half life of a readoactive element to determine time) well the clock is also not synced to any one clock. they know the expected amount of error, and the clock came back slower then the expected error every time.
here's a question at the speed of light they predict time stops, if this is the case would the half life of an element also stop? if so think of the possibilities once you get to the speed of light if your fuel is radioactive it'll nevr decay.
