I am referring to the usual twin "paradox" where one twin remains on Earth while the other one takes a round trip journey on a rocket. I understand how the experience of the twins is not symmetrical, because one is accelerating, and that the solution involves changing reference frames. What I haven't seen in common answers, and what I am curious about, is what would one twin (on the rocket) see if she could constantly look at the other twin's clock. Imagine that the travelling twin had a super telescope and watched the Earth-bound twin's clock constantly during her trip. This scenario includes the following stages:
- Positive acceleration, +a, away from Earth
- Floating freely for a while at velocity +v
- Negative acceleration, -a, to slow to a stop relative to Earth
- Briefly motionless relative to Earth (v=0)
- Accelerating towards Earth at -a until reaching velocity -v
- Floating freely towards earth at velocity -v
- Final positive acceleration, +a, to land on Earth (v=0).
What would the twin on the rocket see on Earth, looking from afar:
- While accelerating away?
- While floating freely before starting the deceleration?
- While decelerating but still moving away?
- During transition (turn around)?
- While decelerating but now moving back towards Earth?
- While floating freely back towards Earth?
- While accelerating to a stop on Earth?
Imagine the traveling twin constantly looking through the telescope and comparing the Earth clock to her rocket clock. I'm looking for an answer like "...now the Earth-clock appears to be ticking slower than her own clock on the rocket". And "...at this point the clocks are momentarily showing the same time." You can keep the math to the bare minimum, in fact no math is best! Thank you in advance.
