I think I'll have a go at explaining this in as simple terms as I can, as if I'm talking to a child.
As the spacecraft with Space Twin accelerates towards light speed, Space Twin will experience and perceive time as normal. A 3 minute egg will still take 3 minutes to cook, his heart will still beat at ~45 beats per minute (he's an astronaut so he must be physically fit, right?).
Time, as he perceives it has not changed.
Back on Earth, Earth Twin will age as normal, his 3 minute egg will still take 3 minutes to cook, his heart will still beat at its normal rate.
Time, as he perceives it has not changed.
When Space Twin returns to Earth after his mission to boldly go where no Space Twin has gone before, his body will have aged no more or less than the mission lasted from his perspective. If the spacecraft's clocks says it was a six month mission, his body will have aged 6 months, but to an outside observer (in this case, Earth Twin) the mission would have lasted much longer.
The space craft may have been away for many years in Earth time, but only a few months according to the spacecraft's onboard clocks. Hence, Earth Twin would have aged at the normal Earth rate but Space Twin would seem much younger.
I really hope this explains it for you (and that I got it right, I'm no expert).
If you don't get it now you are either thick or a troll. I'm going with thick, mainly because you can't spell astronaut correctly (there is no 'g' if you were wondering what error you had made).FCN 3: Raleigh Record Ace fixie-to be resurrected sometime in the future

Would the astronaut be paid six months salary or paid for the duration of the journey in 'earth time'?“New York has the haircuts, London has the trousers, but Belfast has the reason!0

lets not get into relativistic economics, that sounds like a mine field of confusion and bad punsi ride a hardtail0

How about six month pay, but paid in advance into a high interest savings account for when he returns. Everyone wins (assuming the bank still exists when he returns).FCN 3: Raleigh Record Ace fixie-to be resurrected sometime in the future

yes but according to the finance office frame of reference he would be getting much much less than minimum wage :S How much do astronauts get paid anyway?i ride a hardtail0

astronomical amounts.

I was wondering about something..
Do we keep referring to twins 'cos it's the theory of relativity?

I don't think so - in spaceflight, relative to Earth, the astranought twin will experience time in slow motion A 3 minute egg will boil slower, his heart will beat in slow motion . Time will go by more slowly as indicated by the clock on board.
If CCTV is fitted in the spacecraft the Eartbound twin will watch everything in slow motion from his monitor on Earth0 -

Check this out with your physics teacher if you have got one.0

Hmm, who should I trust. 'Astronought' here or my physics degree. Tricky one.i ride a hardtail0

Come on Will, with a physics degree you know I am right -work it out like I worked it out0

no it was aimed at you. Ive had enough of your intelligent, well researched posts. Obviously antontordy is right, despite the fact he has been proven wrong by many experiments, and cannot cite any references.

Original ideas comes from the ability to think thoughts that haven't been thunk before and the bravery to march to the beat of a different drummer.
antontordy's drummer is in the middle of an epileptic fit and no one has thunk those thoughts before because they are stupid!FCN 3: Raleigh Record Ace fixie-to be resurrected sometime in the future

Kings new clothes. Anything einstein says must be right until someone points out that the kings got no clothes on.
Must Go - see you again folks.0 -
all of relativity is based on the OBSERVABLE FACT that the speed of light in a vacumn in constant regardless of inertial frame of reference. What Einstein said has been picked at and modfied loads of times.
So why do you think you are right, and have pointed out a flaw in relativity that no other scientist has ever thought of?i ride a hardtail0 -
Will, call it quits. You can't win and even if you do, what have you won?

Will, are you deliberately trying to open a can of worms. I get the feeling antontordy might be a creationist, or even worse, a believer in 'intelligent design'.FCN 3: Raleigh Record Ace fixie-to be resurrected sometime in the future
