Introduction

Max Tegmark makes the bold assertion that not only do we live in a multiverse, but many different kinds and that base reality is mathematics. These are two metaphysical claims. Max describes four levels of the multiverse. The first is distinguished by being the universe of regular space we can observe - other cosmologists just call this regular space. Another purported solution to this is therefore God did it which God and where they are is another matter. This third level of multiverse is the Evertian quantum multiverse. It's no insult to be called non-science unlike pseudoscience.
