I don't think he was wrong, just misunderstood and I don't understand it
either.

The lorenz transform is symmentrical so mesons see the atmosphere contracted
and the earth based observer sees the point where the mesons are coming from
contracted too.

No, as I explained to you when you were signing as "Abonito",
that's completely wrong.
1) That "point" does not move.
2) "points" cannot contract since they have no length.
Before you try to understand the transformation, you should
first understand what the variables in the equations stand for.
Can you try to explain what you think the variables mean?
