  1. Our Space Time Coordinates: Time, Distances, and Sizes http://www.cs.wright.edu/~tkprasad

  2. Universe • Milky Way Galaxy • Solar System (including the star Sun, the planet Earth,the moonMoon(!), etc) • Planet Earth • Seven Continents and Four Oceans • North America, South America, Europe, Africa, Asia, Australia, Antartica • Pacific, Atlantic, Indian, Arctic • Countries, States, Cities • United States of America, Ohio, Dayton • Russ Engineering Center, Wright State University, 3640, Col. Glenn Highway

  3. Measuring Distances • Average Distance between Sun and Earth = 93 million miles (1 Astronomical Unit) (Speed of light = 186000 miles per second) (1 light second = 186000 miles ) = 500 light second = 8.33 light minutes

  4. Visualizing Distances • If 1 inch is the distance between sun and earth, • then 1 mile is equivalent to 1 light year. • 1 parsec = 3.26 light years

  5. Solar System scaled to Football field

  6. Distances to nearby objects

  7. Distances to Stars

  8. Age vs Distance
