This is my first post and i must apologize for my extreme lack of knowledge of physics compared to your average poster here. I feel compelled to post here because about a year ago it suddenly occurred to me that we might be in an eternal loop and I would like to understand better whether is possible or not. My original thought was, although likely incorrect, if time is infinite (which i now believe that to be debatable) and matter in the universe is finite (I don't have a good understanding if this is true or not), then wouldn't at some point the state of the universe necessarily repeat itself? And if there is one single repetition in the state if the universe wouldn't that mean that all events in matter would unfold as it did the first time creating an endless loop? In talking to a friend about this, I was directed to research multiverse theory which I did to an extent. What I learned about the theory is that it primarily has to do with the existence of an infinite number of universes that exist if traveling enough distance in space. But can that same idea of infinite universes be applied if just looking at time? Or? would the "looped" universe make an infinite number of universes virtually impossible (just looking at time), because a repetition of a state of the universe is much more likely to happen before all imaginable universes gets played out over time. In trying to figure some of this stuff out , I learned a little about the big bang , big crunch theory, but I have a real hard time understanding some the stuff that gets written here because of my lack of knowledge of physics. I'm not even sure if i read some of the answers to my questions or not! lol. One question that I have that are related to my thoughts on this...Is matter finite or infinite? If matter IS infinite, how can empty space exist? what if a rock suddenly appeared in this universe out of nothingness wouldn't we have a larger amount of matter than before and if so how could we call the lesser amount of matter infinite? Also, if both matter and time are infinite would a looped universe even be possible? I would like to add on a personal note , I have never before experienced something like the feeling of excitement that I had when thinking up this possible looped reality. The implications would be interesting. All things that happened in my life happened an infinite number of times in the past and will happen an infinite number of times in the future. Which would bring to question...Would the matter that is my body in the other universes be me? Are the eastern religions somewhat onto something very large (if so probably by luck) in their cyclical view of the world? I have been an atheist all my life and I felt how I imagine a born again christian might feel...I had to "tell the news" so to speak..all my friends heard of my new thoughts. The difference between me and the Christians, however, is that I am truly interested in the truth no matter where the truth takes me and i fully understand that my idea is pretty unlikely, especially given my lack of knowledge of physics. I know that I brought up a lot of questions here, but even the slightest insight to give me a better understanding of my currently unresolved thoughts on this would be greatly appreciated. And again, I am sorry for my low level of knowledge of physics. Thank you.
