I'm very new to the understanding of Hawking Radiation. I don't know much about this theory, but I do know that Hawking radiation works on a Quantum scale. I know that with black holes this theory proposes th idea that over time black hole lose mass because of "Spontaneous appearing positive and negative energy particles Affect the black hole". Negative takes the mass away whil positive manages to escape the black hole resulting in the category of radiation (energy). But how does this all work? And how can particles appear from nothing? I thought "no matter can be created" nor destroyed.
