Body 2 leaves point A 33 years after Body 1 and travels the 48 light years to point B at 99.99995% of light speed.

What I think I know:

- Body 1 takes 58 years to reach point B according to an earth observer.
- Body 1 takes 33 years to reach point B according to an on board observer.
- Body 2 takes 48 years to reach point B according to an earth observer.
- Body 2 takes 14 days to reach point B according to an on board observer.

- If Body 2 sends a message to Body 1 on their departure date
- When will Body 1 receive it (on board elapsed time)

- According to Body 1, how much time will elapse between their arrival at point B and the arrival of Body 2?
