Black Holes Explained: What Is a Black Hole? How They Form?

The video explores the concept of black holes, starting with their prediction by John Mitchell and later observations. It explains star formation, the lifecycle of stars, and the formation of white dwarfs and neutron stars. The video delves into the concept of singularity, black holes, and the event horizon. It discusses evidence for black holes, focusing on Cygnus X1, and introduces Hawking radiation. Finally, it touches on the Theory of Everything, combining relativity and quantum mechanics.
