This picture shows the over all structure of our universe. This is just a small piece, but it is enough to see that matter is organized in strands, or strings.
Lets start from the beginning.
-
The Earth revolves around the Sun.
-
The Sun in turn revolves or circles the center of the galaxy.
-
Our galaxy is part of a group of galaxies called the Local Group.
-
The Local group of galaxies are all part of a bigger cluster of galaxies called the Virgo Cluster.
Now here is where it gets fun.
If you could look at the entire universe at once it would look like a giant spider web, made up of billions of galaxies, and trillions and trillions of stars. |
|
The areas between strands of galaxies are completely empty. You would have to travel Hundreds of miles to find just one atom. |
