Black Hole for Dilettante ： 2020.3 [newly written 2024.6]
This short note is intended for readers to understand the physics of Black Hole. In particular, I have included the short discussion of Defect of Einstein's General Relativity for reference. This proof that Einstein's General Relativity is physically meaningles is quite simple but is exact.
Also some Appendix should be added in order to help young physicists understand physics in depth.
