To my knowledge, it is still a mystery if the universe is finite or infinite in size. Assume the universe is infinite in size. Does it imply that there exist an infinite number of copies of our solar system in the whole infinite universe? I presume that the answer depends whether the solar system can be defined by discrete or continuous data. If there exists only a finite number of states to describe the solar system, I would guess that the same pattern is repeated an infinite number of times in an infinite universe. If a continous model is needed to describe the solar system, I would guess that there exists somewhere in an infinite universe planetary systems as close as possible to the solar system, but not exactly equal to it. Is that right? Thank in advance for your answers.
