I found the tooth fairy, but it turned out to be my dad. ;)
Perhaps my dad is a white hole. As far as I know, white holes are a pheno of math only. They haven't been found because they may not actually exist in real life, but to catch the phrase here, they said that about black holes as well. As for a white hole being against the 2nd law of thermodynamics, that law only applies to this universe. If a white hole did exist, they may not actually exist in this dimension so there would be no contradiction. The white hole probably only exists in mathmatics.
