Hi All,(adsbygoogle = window.adsbygoogle || []).push({});

I was recently trying to understand the Special Theory of Relativity and my understanding of the resolution of the twin paradox is that the person who has accelerated away from the observer and accelerates again to join the observer is the person that grows older. I understand the reasoning behind this.

However, what if I accelerated with respect to a stationary observer and then, after several years, the stationary observer accelerated to get back to me. Or vice-versa.

What is the explanation under those circumstances?

Thanks in advance.
