Star Formation

• Gas clouds come together by gravity
• Then it heats up and gives off light in order to
  cool down
• Then it shrinks and the core heats up until
  fusion starts,which begins the main sequence

Conclusions

• M 13 is about 13.6 billion years old /- 1.5
  billion years, which means that the universe is
  about 13.6 billion years old or older
• This is one of the best methods that scientist
  have used to be able to measure the age of the
  universe
