Presentation Transcript

  1. Black hole modeling and simulating Paul Maynard

  2. Information about stars • Stars tend to be very massive • The sun contains 99.85% of all the matter in our solar system[3] • Nuclear fusion occurs in center of the star • Which produces light and gives of electromagnetic force

  3. What is a black hole? • An object whose gravitational force is so strong not even light can escape it • Black holes are formed from dead stars Picture from [2]

  4. Black hole formation • A star is composed mainly of hydrogen • The hydrogen atoms combine with each other • This is called fusion • Fusion causes a great amount of outward force. Which counter acts the force of gravity.

  5. Example of forces of a star

  6. Black hole formation cont. • When all of the hydrogen is burn off the outward force stops. • If the star is big enough it will collapse into a black hole.

  7. Gravitational orbit equations [5]

  8. Einstein's Equation

  9. More precise equations • Minkowski space-time • Schwarzschild metric • Schwarzschild radius • Curvature

  10. Rotating Black holes

  11. Red shift

  12. C=4(pi)G(Mh)/c^2 Rc = Em (1-Ch/C)^(- ½) [7]
