Well, we just have to take it as it is since the series doesn't delve that much in how things happen literally.

It isn't like other series which uses science to explain phenomenons and stuffs like Mahouka and TMnT (Although I haven't read it personally but I think explanations are given using scientific principles on how things happen ).
