The planet I live on, Earth, is one of eight planets that rotate around a star that we have named the Sun.  The Sun and these eight planets make up our solar system. My solar system is only a small part of my galaxy, the Milky Way, which has been measured to be 1,000 light years in diameter and looks like a spiral with two major arms. To be more specific about my planet’s location in terms of the Milky Way, you can find Earth on Orion which is the minor arm that connects to Perseus, a major arm. My galaxy is one of 67,000 galaxies and is part of a cluster of galaxies known as The Local Group. The Local Group is part of a supercluster known as the Virgo Supercluster. The galaxies in my universe are clumped together in various groups and they all rotate very slowly and it is theorized that because our galaxies rotate, our entire universe rotates as well. In terms of location, the Milky Way galaxy is to the far right of the universe.
            The origin of my universe, as explained by the Big Bang Theory, was essentially protons and neutrons fusing to form hydrogen which then fused to become helium leaving the majority of nuclear matter in my universe to be composed of hydrogen and helium. The beginning of the universe there was just dark matter and over time stars began to form and as more stars were formed and evolved, galaxies formed which got us to where we are now at 13. 7 billion years old. My universe is very exciting because everything is always moving and changing. The galaxies in my universe are moving away from each other (with the exception of one galaxy, Andromeda, which is actually moving toward the Milky Way!). It is fairly universally (no pun intended) understood that the universe will continue to expand forever as the galaxies will continue to move away from each other but it is also theorized that if there is not a lot of dark matter than the universe will have to stop expanding and will begin to shrink until nothing is left.
