This is a basic question regarding Lorentz transformations. Lets say we have two observers - S on Earth and S' which we put on a rocket headed for Alpha Centauri (A.C) =).(adsbygoogle = window.adsbygoogle || []).push({});

If i choose 2 events like this:

- rocket leaves Earth
- rocket arrives on A.C

These two events clearly do not happen on a same place from perspective of an observer S. But what about an observer S'? Would he say that they happen on a same place?

I want to know this so i can use ##\Delta x' = 0## in Lorentz transformations.
