DEFINATION OF MULTIVERSE AND AN EXPLANATION OF MANY EARTHS ETC The World according to DC and Marvel Comics is not a Universe but a Multiverse. What is a Multiverse? One may define a Multiverse as some thing which consists of finitely or infinitely many Universes. Eeach Universe in the Multiverse consists of atleast four space Dimensions and atleast three Dimensions. The possibility of more than than 4 dimensions in Space and more than three dimensions in time cannot be ruled out. There are different types of Universes in a Multiverse. 1] Identical Copy. In this type of universes each and every thing of the universes are same including living and non living things ,events acts, etc. They occur simultanously. 2] Similar Copies. 2.1] Less Identical Copy. In this types of universes an event in present might be past or future in an other universe. 2.2] Further less Identical Copy. In this type things are same yet acts are different. If a person is good in one universe he might be bad in an other universe. A thing be destroyed in one but continues to exist in other. Yet each thing must have a analogue either in present or future. 3]Semi Similar Copies. Earth may be habitant in one universe and be not habitant in some other universes. Krypton may still exist in one and earth may be destroyed in it ,while Krypton may be destroyed in an other while earth may exist in it, or both still continue to exist yet both are not suitable for life forms in one, and both exist and both are suitable for life forms. 4] Semi Dissimilar Krypton may exist in one but do not exist in other, yet earth exists in both. Or earth exist in one but Krypton in both.
