## Main Question or Discussion Point

Hi All,

Regarding the twin paradox, is it true that if both twins had travelled in opposite directions and turned back, both would be still with the same age?

Tell me if it is right to think like this:

The central points in "aging faster" are 1)the non simmetric set up and 2) the fact that one of them has felt slower time because of being subjected to an acceleration (equivalent to gravitational) field.

And the last one:

Tell me if it makes sense to propose a problem where one of the twins (A) goes to a trip of one year (thus acquiring physical reasons to age slower) while the other (B) stays at the Earth, and the problem asks you to calculate the amount of mass that would have to be added to the Earth when A has left in order to compensate in B the difference in aging between them.

Best Regards,
