The Universe is both infinite and eternal growth, but the amount of particles contained in a given volume of this space is finite, also the number of possible ways to arrange these particles is also finite. So we have a finite number of ways to arrange a universe, but infinitely many universes to arrange – so, says the mathematics that all possible arrangements will occur, not just once, but an infinite number of times. And, therefore, that even you with your newspaper, and I with my computer, will exist in more than one copy.
Not just you and me entire world can be found in far away in this space time.
These worlds are thought to be located in parts of space that because of the room’s expansion moving away from us faster than the speed of light, so that it would be impossible for us to reach them even if we traveled at the speed of light forever .
