Keep in mind I am a complete layman when it comes to physics. Is the Poincare recurrence time the time it will take for the universe to be exactly in the state again as it is now or the time before the universe will even begin to be able to starting producing basic patterns from chaos? What is to keep the rearrangement of patterns being like the show sliders where there would be alternative histories(but in are own reconstructed universe rather than parallel ones) before we return to the history we are familiar with? Or is it just or own history that we just experienced that can repeat? What would keep things from being weirdly out of order like people from different eras being born together?
