A more current view of white holes takes into consideration a revision to the standard model of the
big bang theory which states that the big bang is an explosion that happens within a black hole, with the
expansion that follows the traditional interpretation of the big bang, expanding into infinite space inside the black hole. In other words, a miniature universe is created at the core of the black hole, which expands into extra dimensions outside of this universe. The expansion taking place in this new miniature universe, if it could be perceived from an observer from this universe, could be looked at as a white hole. Matter that could not escape the intense gravitational pull of the black hole in this universe is instead sent speeding into the newly expanding baby universe. Using that logic, one could assume that our universe itself is a white hole. Hypothetically, this model could be used to explain the increasing rate of expansion of this universe: as matter from our parent universe is engulfed by our parent black hole (the black hole that created our universe), our own universe is fed this matter which could possibly have something to do with
dark matter and
dark energy, which currently is thought to contribute to the increase in the rate of our universe's expansion.
