  1. IN THE BEGINNING…….

  2. EVERYTHING!

  3. EVERYTHING!

  4. STARTS EXPANDING….. EVERYTHING! ENERGY INCREASING, BECOMING LIKE A BOMB…….

  5. Tick tick tick……

  6. BOOM!

  7. The Big Bang • Not really an ‘explosion’ • Universe expanded rapidly as a whole • (Universe is still expanding today as a result of the Big Bang) • Matter was created in the form of tiny particles (protons, neutrons, electrons) • Too hot for normal ‘stuff’ to form (eg atoms, molecules)

  8. COSMIC ‘SOUP’

  9. COSMIC ‘SOUP’ PROTON NEUTRON ELECTRON

  10. 300,000 Years Later….. • Universe much cooler, atoms start to form….. • Hydrogen, Helium, normal ‘stuff’

  11. Universe is now a GAS HELIUM HYDROGEN

  12. GRAVITY!

  13. Gravitational Collapse • We started with a uniform gas • Small regions became more dense • The denser regions had larger gravity and started to pull other particles towards them • The gaseous Universe began to look ‘clumpy’

  14. What have we learnt? • The Universe started with a BIG BANG • Gradually the particles were drawn together under GRAVITY to form STARS and GALAXIES • Many stars have planets around them • The fate of the Universe is uncertain…

  15. THE END
