Could The Theoretical White Hole Actually Exist?
You may know that a black hole is said to suck matter into a single point of entry. But what if you reversed that formula? White holes are the theoretical opposite of black holes, thought to expel matter from a single point with no entryway. White holes almost certainly do not exist-there would need to be not even a single speck of matter within the event horizon for one to form. White holes break the second law of thermodynamics, because where black holes increase entropy, white holes would decrease entropy.
