 That's clearly not Minkowski's diagram (did he have suitable drawing software in the 19th century?), but someone's interpretation of it. I hope you're not adopting Thomas Heger's habit of lying about who wrote what.

this wasn't my diagram, but looks actually correct.
My own explanation for the so called twin paradox was a bit similar, but based on the idea, that acceleration causes the relativistic effects and not velocity.
Such a travel would cause a situation, where a spaceship gets accelerated from - say- Earth, to reach a certain travel velocity to a distant star and a planet there.
Then the spaceship gets decelerated in order to land there.
Then the spaceship starts from there, travels back to Earth and needs to decelerate here.
This requires four instances of acceleration (two positive and two negative), which should cancel the effect.
