Black hole modeling and
simulating
Paul Maynard
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
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]
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.
Example of forces of a star
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.
Gravitational orbit equations
[5]
Einstein's Equation
More precise equations

Red shift
C=4(pi)G(Mh)/c^2
Rc = Em (1-Ch/C)^(- ½)
