Is there only one structure of the universe?

[student34]

(See illustration) Object A is moving, to the right, really fast towards object B on the x axis. At (0,0) they meet. There are two rocks next to each other ahead of the speeding object A. The two rocks are shown as world lines red and green as they would exist for each observer. Assume that the length contraction is 1/2 for object A.

There would seem to be two different structures of the same thing in the universe. Is this correct?

No. You've asked the same question in multiple previous threads, and the answer hasn't changed.

Thread closed.
