I have multiple reasons why white holes do not exist. But first let’s go over what a white hole is. It is: the same as a black hole, but in reverse. Instead of sucking up matter and light, it spits it out. This spit out matter and light are said to have been from a black hole, transported to the white hole by a wormhole or inter-space bridge. This is not true because: first, it violates thermodynamic law number 2. Second, the wormhole cannot be produced by a black hole because the gravitational sheer that a black hole produces would be too great for a formation of a wormhole, meaning it would be impossible for it to form because of all the gravity produced by the black hole. Third: we know that it takes a significant amount of gravitational energy or force in order to reshape the fabric of space and form wormholes, but is that amount equal or less than the amount generated by black holes? Not even close. As we know, black holes are sort of shaped like funnels. They suck up matter and light and channel it into the core of their singulaty, where it is pretty much destroyed. Well, because a black hole channels all of its energy forward instead of backward or any other direction, no energy is going past the core to make a wormhole, therefore, not transmitting their matter and light to a white hole, thus rendering white holes nonexistent.
