Is there only one structure of the universe?

In summary, Object A is moving towards Object B on the x axis at a high speed and they meet at (0,0). Two rocks are shown as world lines, one for each observer, with a length contraction of 1/2 for Object A. It appears that there are two different structures of the same thing in the universe, but this is not correct. This question has been asked before and the answer remains unchanged.

(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.

FAQ: Is there only one structure of the universe?

What evidence supports the idea that there is only one structure of the universe?

Scientists have observed that the laws of physics and the fundamental constants of the universe are consistent throughout all regions of space and time. This suggests that there is only one underlying structure to the universe.

Can there be multiple structures within the universe?

While it is possible that there are multiple structures within the universe, there is currently no evidence to support this idea. The laws of physics and the observed consistency of the universe suggest that there is only one structure.

How do scientists study the structure of the universe?

Scientists use a variety of tools and techniques to study the structure of the universe, including telescopes, satellites, and computer simulations. They also analyze data from observations of cosmic microwave background radiation, galaxies, and other celestial objects.

What are some theories about the structure of the universe?

There are several theories about the structure of the universe, including the Big Bang theory, the Steady State theory, and the Inflationary theory. These theories attempt to explain the origin and evolution of the universe and its overall structure.

Could our understanding of the universe's structure change in the future?

As with any scientific theory, our understanding of the universe's structure is subject to change as new evidence and technologies become available. It is possible that future discoveries could challenge our current understanding and lead to new theories about the structure of the universe.
