Brain cell

On the left is a picture of a single brain cell. On the right is an image of the universe.

Are we in someone’s brain? Are the planets that we are familiar with just atoms for another, much larger, universe?

That Pale Blue Dot in the image above is earth. This image was shown by Carl Sagan in 1994. It was taken by Voyager 1 when it was floating away from earth.
