**New Theories / What is non-returning twin paradox? **

« **on:**17/09/2023 08:30:13 »

This is a slightly modified twin paradox to distinguish the effects of relative speeds and acceleration.

Twin A started a journey to Alpha Centauri 4 light years away in a space ship moving at 0.4c. He is expected to arrive 10 years later, according to earth observer.

Twin B stayed home to improve the space ship, so he can go to Alpha Centauri 5 years later at 0.8 c.

Classical physics calculation predicts that they'll arrive at Alpha Centauri simultaneously. Does special theory of relativity predict the same?

How old are they when they meet up at Alpha Centauri?
