Hello everybody,

Today in class we learned about atoms and our universe. I find it so interesting that there could be something as small as an atom and something as big a our universe. I I learned that each star we see in the sky is a planet, and when you look at the stars, it is basically like looking at the past because light years (even though they travel super fast) can’t get to us right away all the way from the stars, so the stars that you look at in the sky might not be there anymore and the stars might look totally different. Another thing is that a man sent a machine into space over 40 years ago and it is the fastest moving thing in the world. It only just reached the edge of our solar system last year! Think about how big our solar system is, but then if you look at the size of our solar system compared to the Milky Way galaxy, it looks tiny. We also learned about atoms using a grapefruit as an example. There are tons of atoms in a grapefruit. If you make the grapefruit to be the size of the earth, an atom would be about the size of a blueberry, that’s a lot of blueberries! I find it so interesting and confusing to learn about atoms and to learn about our universe.

Bye!
