How The Universe Began

       How The Universe Began: Big Bang Theory
     The universe started out as a tiny little dot. That little dot had alot of energy inside it. One day,  that dot released it's energy. Astronomers called this the Big Bang Theory, which explains how the universe began. Right this moment, the universe is expanding. Because of the expansion, the constant movement of spreading, galactic objects are also moving along. This constant moving of the universe is powered by an energy called the dark energy. Astronomers say that the universe's expansion is accelerating, expanding faster than before. Think of this expansion like an air conditioned room except that the walls of that room is endless and the cool, invisible air is flowing in at an accelerating rate. The air fills the empty room like the universe filling in the empty space that has yet to be occupied. The universe is about 13.8 billion years old. 
     The universe is mysterious. Our present technology hasn't been able to crack this mystery, yet. Whether the universe is infinite or not and what is outside the universe are questions that astronomers still not know. The universe is like a code and our future generations of astronomers may be able to crack it with their knowledge and advanced technology.
