how might the universe end? cold or heat or expansion?
Let Me Tell You If you are not a Space Lover that there are Multiverse.. So what happened for the end here will not happen at the another.. quite seems same and huhhh…. Time paradox…. Well there no is no end and no start its in loop because there are multiverse so a single theory or idea ( Not even mine) will lead to a proper answer. All Answers can just give path to another question and the present answers are just a relief as like siting on a Sofa and we try to find new one before it get too old.
