• What is a Black Hole?
• A black hole is a region of spacetime from which
  nothing can escape
• Tennis ball example

Process of creating a black hole Nuclear Fusion
stops? Stars Gravity pulls material inward and
compresses core? heat? supernova explosion?
Neuron star? Continues to shrink Black hole
