Let there is a triplet of A, B, and C on an asteroid initially. A stays on an asteroid while B and C set out for a long space journey with high speed (say 0.5c and 0.9c) at the same time in the same direction relative to A. Assume each 10 years old at the time of departure. B and C are gone for 60 years relative to A. Afterward, B and C return home at the same time and reunited with A on an asteroid.

What would be the age of A relative to B and C?

What would be the age of B relative to C and A?

What would be the age of C relative to A and B?

For person c, relative to a they are gone for 60 years

This works out to be a time dilation factor of 2.29

So for person c only 60/2.29 years have passed ~ 26 years

Person b has a time dilation factor of 1.15

so 60 / 1.15 ~ 51 years has passed

Person A is 70,

Person B is 61,

Person C is 36
