Have you ever wondered how big the universe was? Assume we are traveling at the speed of light (186,000 miles/sec) from the sun to the end of our solar system. At the SOL and 5 hrs 31m later we have traveled 3.5 billion miles to the end of our solar system. Now we travel in the direction perpendicular to our galaxy. Behind us the planets and sun quickly vanished. The emptyness of space has broken only by the light of stars so distant they don't yet appear to move. Finally on April 5th of the 5th year traveling at the speed of light we reach Alpha Centauri A, the neareast star to our solar system. We have now traveled over 25 trillion miles. 100 lt years from the sun gas and nabulas material from the arms of the milky way fill our view. At 1000 lt years the galaxys arms and disks become more defined. But it is not until we have traveled at the speed of light for 100,000 light years do we recongnize the entire Milky Way Galaxy. From this point forward every point of light you see is not a star but an entire galaxy. If you add 22 zeros behind 10 and whatever figure it is, that is how many stars are in each galaxy. 5 million years after traveling at the speed of light the Milkyway seems part of the 30 galaxies cluster known as a local group. 50 million light years out we enocunter the Large Burger cluster containing more than 2000 galaxies. And so it goes as our journey takes us deeper into the cosmos. Finally after 10 billion years we stop to look at a theoritcal view of the universe. Now think that we are just this one star out of 1,000,000,000,000,000,000,000 10x22 in one galaxy out of billions.

Are we alone?
