First the traveling twin needs to slow down.

Then it needs to change direction...

maybe slowing down to make a uturn...

after the uturn it needs to speed up again..

then when it reaches the earth...

it needs to slow down again.

A lot of time is lost with all dis

uturns and slowing down.

But whp bothers to measure it?
