To learn about black holes, a foundational understanding of relativity is essential, requiring knowledge of physics and mathematics. Beginners can start with qualitative resources before moving to more complex texts. Recommended books include "General Relativity from A to B" by Robert Geroch and "Spacetime Physics" by Taylor and Wheeler, which cover essential concepts without heavy mathematical requirements. For those interested in Hawking radiation, further simplifications and explanations can be found in online physics forums. A solid grasp of calculus will enhance understanding and problem-solving related to black holes.
