I have to write an essay up on two ways how black holes both support the modern laws of physics, and two ways how they defy the modern laws of physics. I'm looking at newton’s law of gravity, and general relativity, though i bet theres loads more of laws i could look at, i reckon some quantum stuff may come up but I'm not sure what law that would go under. I know ways black holes follow the laws of physics but I still need two ways they break laws of physics. I know there's still many things unknown about black holes and physics in general really, but I am focusing on just two direct laws they break. I've tried researching but I am having a hard time looking for answers.
