Information about stars

• Stars tend to be very massive
• The sun contains 99.85 of all the matter in our
  solar system3
• 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.
