The discussion centers on the concept of different structures of the universe as illustrated by the interaction of two objects, A and B, with specific reference to their world lines. The scenario suggests that due to relativistic effects, particularly length contraction, observers may perceive different structures. However, the consensus in the thread is that despite these perceptions, there remains a singular underlying structure of the universe. Repeated inquiries on the topic have yielded consistent responses, leading to the closure of the thread. The conclusion affirms that there is not more than one structure of the universe.

(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.

Thread 'Am I understanding the concept of proper frame of reference?'

MOVING CLOCKS In this section, we show that clocks moving at high speeds run slowly. We construct a clock, called a light clock, using a stick of proper lenght ##L_0##, and two mirrors. The two mirrors face each other, and a pulse of light bounces back and forth betweem them. Each time the light pulse strikes one of the mirrors, say the lower mirror, the clock is said to tick. Between successive ticks the light pulse travels a distance ##2L_0## in the proper reference of frame of the clock...
