Abstract: This presentation, aimed at the undergraduate audience, will look at the hypotheses offered by the famous theoretical physicist, Stephen W. Hawking concerning radiation that might come from Black Holes. If this radiation occurs, it would mean that Black Holes are not so black after all. The talk will be a qualitative discussion (mathematics kept to a minimum) about Professor Hawking’s main ideas that come from General Relativity and Quantum Physics. Using these ideas, he creates the notion that Black Holes might radiate energy away like a hot object and evaporate! This hypothetical phenomenon is called: “Hawking Radiation.” It is also fascinating to see how Newton’s Classical Physics, Einstein’s General Relativity, and Quantum Physics each treat the idea of “vacuum” differently.
