By putting forward hard formulae that can be used to calculate hard numbers like those above, the duo from Griffith University could provide a jumping off point for real, useful applications. If, for instance, the interaction of different universes could influence the speed of a chemical reaction, then knowing the mechanics of how those universes interact could help with virtually any area of modern science. A more precise and far-seeing way to predict how quantum phenomena will proceed could impact everything from industrial processes to quantum cryptography.
