1. The Big bang and the universe

2. The Beginning 10-20 billion years ago There was nothing Singularity-thought to be origin Appearance of a ball of mass Hydrogen and a little helium

3. The big bang Expansion NOT Explosion Trillionth-Trillionth of a second Imagine balloon expanding instead of popping First proposed by George Lemaitre

4. What happened next Slower expansion Cooling, appearances of forces and particles Radiation, x-rays, radio waves Packets of gas Formation of galaxies and planets

5. Evidence Background microwaves Universe still expanding Universe had beginning Theory of Relativity being proven Abundance of lightest elements

6. If expanding, must have a beginning Nothing can travel faster than light Gravity distortion of space and time Theory of Relativity

7. Road trip Scale of universe based on light years

8. Structure is a hierarchy Voids Sloan Great Wall Dark Matter Structure

9. What we still don’t know Where the singularity came from What caused initial expansion What will happen? Big Rip Big Crunch

10. Our solar system

11. Got gas 4.56 Billion years ago Explosion of supernova Collapse of nebula Nebular hypothesis

12. The sun Gas from collapse of nebula concentrates Conservation of Angular Momentum Becomes hotter and denser as spins Start hydrogen nuclear fusion White Dwarf

13. Terrestrial planets Mercury, Venus, Earth & Mars Gases condense into rocky material Rock and metal debris come together Become larger and increase gravitational pull

14. Jovian Planets Jupiter, Saturn, Neptune, & Uranus Gases condense into ices Ices come together Capture leftover gases

15. Motion Tilted 90 degrees “Bouncing” through the galaxy 217.215 k/s 226 Million years

16. You are here Milky way galaxy Spiral arm Solar system located on Orion arm It’s difficult to tell exactly where Constant expansion Instead, described as when
