Black holes are predicted by the General theory of relativity. In this video, I have covered the basics of a black hole and the spacetime curvature, and how it is measured by Einstein's general relativity. I have explained the fundamental idea behind the formation of black holes, the types of black holes, what is a Schwarzschild radius and rotating and nonrotating black holes, frame dragging, and other important concepts. Finally, I have shown what is meant by time travel around the black hole.
