One Tiny Speck ... If you step outside on a night that is clear, you will agree with what this lesson talks about. Which is "We are only but a mere tiny piece of this vast universe, but what we do and learn can affect all things in the places that we go." On that clear night you most likely will see hundreds and hundreds of stars that are uncountable.There are about 6,000 stars we can see with the naked eye alone. Even though those are the stars we see, there are millions of billions more out there that we can't see but can sense with radio telescopes. There are also other objects out in the depths of space (e.g. asteroids, comets, neutron stars, etc.). Although you are but a mere piece, you can do and change many things that happen here on Earth.
