I got the impression matter can't be created or destroyed, it is interchangeable with energy.  In which case, could it be that matter is drawn in to a black hole, somehow converted in to energy then ejected from a white hole? 

So purely on a speculative idea

So how do we find these white holes, perhaps we have already found them as we can detect things like gamma ray bursts or neutrino emissions but can't always explain them,  perhaps these are related to white holes and we are observing the release of energy in to space as these or similar phenomenon
