It is easy to confuse multiverse proposals because many divergent models exist. This overview defines the characteristics of ten popular multiverse proposals. The characteristics which are compared to our universe are: initial conditions, values of constants, laws of nature, number of space dimensions, number of universes, and fine tuning explanations. Multiverses are predictions based on theories. Focusing on each theory’s assumptions is key to evaluating a proposed multiverse. Future scientific experiments may validate selected assumptions. Using intuition as perspective, theories supporting multiverses have “strange” assumptions, but nature is not always intuitive.
