Do we live in a multiverse made up of infinite universes?

My fourth novel EMISSARY deals with the possibility that we live in a multiverse made up of an infinite number of universes. For most of its history, the idea of a multiverse was the domain of science fiction and some rare speculation from physicists. In recent years, though, the idea that our Universe may be just one among many has gained traction in two different areas. The string theorists think it may help explain why, if there are a huge number of possible universes, we ended up in one with the properties we see around us. Meanwhile, cosmologists are realising that inflation, which is the only way we know of to get from the Big Bang to our Universe, necessarily implies the creation of other universes.
