Well, from what little I've been able to ascertain, Goodland is more than likely a pocket universe that is able to change locations at will, with the villa in the metaphorical eye of the storm, which explains why we don't get flung to the far corners of the multiverse every time this place changes. Or home.
And the multiverse, or the manyverse, is the existence of infinite universes that comprise everything that exists, and each universe within the multiverse is a different Earth, and the reason why we're usually not aware of each other or able to interact with each other, is because each Earth vibrates at different speeds. We thought there were 52 different Earths, although later calculations estimate at 1900, and now with [...] this, it's fair to say it's infinite.
