 Speaking of relative size. How about the following images... Our Galaxy is in a group of galaxies they call the "local group." There are said to be about 45 galaxies in this group.

Our group of galaxies is just a part of clusters of groups of galaxies. They pointed the Hubble telescope into deep space in an area they thought was relatively empty and were surprised to see thousands of galaxies.

As of now we don't have instruments powerful enough to see out even further but they have used computers to extrapolate what they think it would look like. The following image is what they call our "local universe" made up of strings of clusters of galaxies.

And the following image is what the computer extrapolates think it would look like even farther out.

And even farther yet.

Looking out across unimaginable distances at things that are unimaginably large it amazes me how much it resembles the subatomic universe of electrons and protons that we can see with our most powerful electron microscopes. See Molecular Expressions It also amazes me that with such an astounding world we live in we allow ourselves to be consumed with so many petty things.

 All the water in the world contained in a sphere.

This picture shows the size of a sphere that would contain all of Earth's water in comparison to the size of the Earth. The blue sphere sitting on the United States, reaching from about Salt Lake City, Utah to Topeka, Kansas, has a diameter of about 860 miles (about 1,385 kilometers), with a volume of about 332,500,000 cubic miles (1,386,000,000 cubic kilometers). The sphere includes all the water in the oceans, seas, ice caps, lakes and rivers as well as groundwater, atmospheric water, and even the water in you, your dog, and your tomato plant.


interesting facts....

In fact, there is a hundred times more water in the ground than is in all the world's rivers and lakes.

The air sphere measures 1999 kilometres (about 1242 miles) across and weighs 5140 trillion tonnes (about 5059 trillion tons). As the atmosphere extends from Earth it becomes less dense. Half of the air lies within the first 5 kilometres (about 3 miles) of the atmosphere.

Earth seen from 4 billion miles away, photographed by Voyager 1 on June 6, 1990.

Of the “pale blue dot,” astronomer Carl Sagan said, “That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every ‘superstar,’ every ‘supreme leader,’ every saint and sinner in the history of our species lived there — on a mote of dust suspended in a sunbeam.”
