Suppose there are two muons. In view of muon A, muon B is moving to it. And vice versa.

Is there still shorter distance?

I am really confused with the shorter distance.

One of the reasons is length contraction is a reciprocal effect. And length of an object is supposed to measure two points at one instant.

For the distance, it is not a reciprocal effect in the example above. And distance is measured by two points at different time.

To find out "Is there still shorter distance?", how do I solve it?

Using Spacetime?
