Our universe is a large and unimaginable expanse of dust, gas, stars, clouds, galaxies, and life. If you could look at the entire universe at once it would look like a giant spider web, made up of billions of galaxies, and trillions and trillions of stars. http://www.kidsastronomy.com/universe.htm Astronomical observations indicate that the universe is 13.73 ± 0.12 billion years old and at least 93 billion light years across. The Big Bang is a cosmological model of the universe that has become well supported by several independent observations. The big bang theory proposes that the universe was once extremely compact, dense, and hot. Some original event, a cosmic explosion called the big bang, occurred about 13.7 billion years ago, and the universe has since been expanding and cooling. The balance between gravity compression and outward thermal pressure controls the rate of the nuclear fusion reactions.
I don't realy know how this will be helpful in the future. Just allows you to know more about where you live.
