They're surely not carbon-copy of our own world because the constellations differ from one land to another (Hook said so in 3x05). So either they're other planets scattered across different portions of the galaxy or possibly the univerrse, or it's other universes altogether, roughly similar to ours but differently shaped. I'd say the latter,  because if magic could be possible in the same universe far across the galaxy, why wouldn't it be possible on Earth?
