Reductionism is seen in cases like puzzles. We can break puzzles into pieces and then remake the entirety. So if we have all the pieces of the puzzle, we can remake the puzzle even if we take some of those pieces to another side of the Earth. If we can transport those pieces back, that allows us to remake the puzzle. But that is possible only if those pieces are not destroyed. Reductionism can explain the whole universe. The idea in this thing is this: all systems have a limited number of particles, or some other actors. That means if we turn the system into turbulence or entropy, we might not recognize the system the same as it was before the process started. But the particles that create the system are the same. So theoretically, we can remake and reorder those particles into the same form and order that they were before the process started, without depending on the size of the system. The requirement is that the system is stable. If we think of a situation, a tornado takes our ...
