7. Astronomy & Our Lives
What could learning about the planets and stars possibly have in common with my life now??

8. What have we learned? Facts:
Seven Days/Week, “Moonths” and “Dis-asters”
You most likely aren’t an Aries (or whatever sign you thought you were!)
Distance ≠ Seasons!
Orbits are just controlled, continuous falling!
The world will not end in 2028 (at least because of Asteroid XF11)
There are thousands of planets orbiting other stars…

9. What have we learned? Ideas:
We humans live for an “eye-blink” of time relative to the stars

10. What have we learned?

11. What have we learned?
Ideas: We humans live for an “eye-blink” of time relative to the stars
But in that blink of an eye, we can imagine infinity

12. What have we learned?
Ideas: We humans live for an “eye-blink” of time relative to the stars
But in that blink of an eye, we can imagine infinity, visualize black holes

13. What have we learned?
Ideas: We humans live for an “eye-blink” of time relative to the stars
But in that blink of an eye, we can imagine infinity, visualize black holes, and explain how the Sun shines for a billion years.

15. What have we learned? Ideas:
If the Earth was a grain of cream of wheat….
The Sun would be an orange ~12 steps away

Pluto would be at Hesperian & Depot roads

18. What have we learned? Ideas:
If the Earth was a grain of cream of wheat….
The Sun would be an orange ~12 steps away
Pluto would be at Hesperian & Depot roads
The next nearest star would be 1000 miles away, in El Paso Texas

19. What have we learned?
Nearest Star
1000

20. What have we learned? Ideas: If our Milky Way Galaxy …
was the size of the Bay Area….

21. What have we learned? Ideas:
If the Milky Way Galaxy was the size of the Bay Area….
The Solar System (to Pluto!) is a grain of Cream of Wheat
The nearest stars would still be ~25 feet away
Around Chabot would be ~120,000 other grains of Cream of Wheat representing other solar systems!

22. How big is the universe?
The Milky Way has as many stars as grains of sand on all Earth’s beaches
This slide gives our favorite way of giving students a sense of the size of the observable universe; be sure to note we are talking about the OBSERVABLE universe, since we do not know the extent of the ENTIRE universe. . 22

24. What have we learned? Ideas: Science is not about certainty
Many hypotheses start out wrong!
“We are trying to prove ourselves wrong as quickly as possible, because only in that way can we find progress.”
― Richard P. Feynman

25. What have we learned? Ideas: Science is not about certainty
Many hypotheses start out wrong!
But …
Science is self-correcting
Multiple tests
Independent Experiments by others

“But, soft! what light through yonder window breaks? It is the east, and Juliet is the sun.”  ―  Romeo and Juliet
“Doubt thou the stars are fire; Doubt that the sun doth move; Doubt truth to be a liar; But never doubt I love.”  ― William Shakespeare, Hamlet
The Falling Star
  by Sara Teasdale I saw a star slide down the sky, Blinding the north as it went by, Too burning and too quick to hold, Too lovely to be bought or sold, Good only to make wishes on And then forever to be gone.

29. Stars
Alone in the night On a dark hill With pines around me Spicy and still,

30. And a heaven full of stars Over my head, White and topaz And misty red;

31. Myriads with beating Hearts of fire That aeons Cannot vex or tire;

32. Up the dome of heaven Like a great hill, I watch them marching Stately and still,

33. And I know that I Am honored to be Witness Of so much majesty.

34. Who will I have been when I am gone?

“Nobody ever figures out what life is all about, and it doesn't matter. Explore the world. Nearly everything is really interesting if you go into it deeply enough.”
