## Main Question or Discussion Point

If we add a third observer to the twins paradox at the turnaround point (at rest with earth), and with a clock that was synched with the other two when the ship left earth, what will that clock read when this third observer sees the ship turn around?

Assuming v= 0.8c, distance = 8 ly.

Also, since this third observer and the ship's twin could look at each other's clocks (locally), what would each observe the other's clock to read?

Thanks,

Al
