Our actual universe expands only once, according to scientific evidence, and has no edge or center. Observers who live in spiral galaxy number 5 at the "bottom" of the universe see all other galaxies moving away. (Place your mouse cursor on galaxy 5.) Conversely, observers in all other galaxies see galaxy 5 moving away.

 

 

 

 

Observers who live in spiral galaxy number 46, above the "center" of the universe, see all other galaxies moving away. (Place your mouse cursor on galaxy 46.) Conversely, observers in all other galaxies see galaxy 46 moving away. No matter which is your home galaxy, you'll see all other galaxies moving away.

 

 

Observers in galaxy 5 measure the distance and velocity of other galaxies, and the results are plotted below along with the best fit line. Notice that this plot is consistent with measurements of real galaxies.
