Black Holes Classical approach Escape velocity: as M increases or R decreases, v esc increases at some point v esc = c for M = 1 M sun R = 3 km this object is a black hole nothing, not even light can escape its gravity Schwarzschild radius (event horizon) point at which v esc = c R GM 2 v esc =
Black holes in general relativity gravity is enormously strong near a black hole must use GR where space-time curvature becomes infinite is the Schwarzschild radius the black hole is a singularity inside this space and time become very complicated here

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
