Black Hole

• Idea First Proposed in 1783 by John Mitchel

• Modern Name “Black Hole” invented by John Wheeler in 1952

  • Idea follows from Einstein’s General Relativity
  • Space time is curved in the presenceof matter
  • If there is enough mass, one solution of equations is a singularity: Spacetime is curved on itself to form a “Black Hole”
  • A Black Hole means that the effects of gravity are so strong that nothing, not even light, can escape
  • If an object falls toward a black hole, time slows down until it ceases at the “edge” of the black hole
