Twin Paradox

One is in a gravitational field. The other is in an accelerated frame. How does relativity say ?

Imagine three atomic clocks. Problem U-turn will vanish.

Perhaps, the above had been mentioned by someone.

It is my opinion there is no U-turn problem because the time differences occur anytime the ship moves faster than the earth through space.

The ship had to accelate to leave the planet and again to return to it.

Here is my essay, "The Time and Motion Relationship" at

Anytime, anyywhere, only Newton’s time flows, i believe. So, problem twin paradox doesn’t exist. See the following.

Two fiber-optic cables are laid between the north pole and the equator. A laser beam (frequency is constant) emitted from the equator is reflected at the north pole and is coming back. Frequency at the three points (and every optional point of the cable) is the same. Relative motion or difference of gravity will not cause time dilation.

There are a few other proofs.
