But they haven't been falsified, yet. You're welcome to try. Back when quantum mechanics was new, some people who only knew the popularizations thought along these lines: If everything is "waves" then we could have two different sets of waves, superposed - filling space and time and each set would define a world, but the worlds would know nothing of each other. Some great old science fiction and fantasy was based on that premise. I particularly remember "The Ship of Ishtar". But quantum physics doen't really say that, and neither does superstring theory. The nearest thing I know is one of the superstring attempts to explain the "Dark Matter". In this variation one of the hidden dimensions is just a line segment, a finite piece of line with two ends. Then there are two worlds, one at each end, but really it's like the two faces of a board. Our universe is one face, and the dark matter universe is the other, and what is in between is not wood, but the void, across which only gravity can pass. So we - that is our galaxies - feel the gravity, but we don't see the matter.
