Science literacy is being plugged into the forces that power the universe. There is no excuse for thinking that the Sun, which is a million times the size of Earth, orbits Earth.

If the whole world shared such experiences, we would then have common dreams and everybody could begin thinking about tomorrow. And if everybody thinks about tomorrow, then someday we can visit the sky together.

We are in the universe and the universe is in us.

In life and in the universe it's always best to keep looking up.
