Insignificant or small?
Here's a hint, if you mean small:
heasarc.nasa.gov - Cosmic Distance Scales...
.......The Earth is then about 1.3 cm in diameter (the size of a grape). The Moon orbits about a foot away. The Sun is 1.5 meters in diameter (about
the height of a man) and 150 meters (about a city block) from the Earth.......A human on this scale is the size of an atom; the nearest star would
be over 40,000 km away!
So the clue is: If everything was reduced in size by a factor of a billion a human would be the size of an atom.
So divide the rough dimensions of a human by 1,000,000,000 and we're close to the size of an atom?
Another clue: A human hair is about as thick as 500,000 carbon atoms stacked on top of each other.
And I read if an atom was the size of a marble then our hand would be the size of Earth. That's a big
This is a start!
Ok, so we've just picked a few clues. We need to find more. Another one I find by googling the size of the observable universe. (Since the
non-observable universe may be infinite, we'll just focus on the observable) Apparently it's a sphere and it's 92 billion light years across. 1
light-year is 5.878625 trillion miles. So the sphere is 92 billion X 5.878625 trillion miles across, or 5.878625x1000x1000x1000x1000x1000x1000x1000x92
Here's a very cool interactive scale graphic for small objects starting with a coffee bean and going down to a carbon atom:

EDIT: If I recall right, the relative distances between stars - versus their size - is more dramatic than the distances between galaxies.
