Hi Everyone,
I've managed to confuse myself with a mutilated thought experiment. A half twin paradox. Imagine a twin, Paul travels away from Earth at 8/10c while peter stays at home. Because of time dilation paul reaches a planet by his clock, in one year. Peter registers Pauls arrival at around 1 and a half years. Now if Paul does not change reference frames and continues in steady motion, peter moves at the same speed relative to Paul as Paul does relative to peter. So when Paul arrives at the planet he reads 1 year on his clock, and Peter reads 1.5 years for Pauls arrival, and yet when Paul arrives he reads Peters clock as just short of one year.
Basically I am just not sure what happens in the case of the twin paradox where the twin that leaves Earth neither stops nor changes direction. Is there some kind of simultaneity involved or are they each (relative to the other) in a range of times for each instant.
Many thanks
